-1) Entry point for arch/powerpc
+1) Entry point for arch/arm
+---------------------------
+
+   There is one single entry point to the kernel, at the start
+   of the kernel image. That entry point supports two calling
+   conventions.  A summary of the interface is described here.  A full
+   description of the boot requirements is documented in
+   Documentation/arm/Booting
+
+        a) ATAGS interface.  Minimal information is passed from firmware
+        to the kernel with a tagged list of predefined parameters.
+
+                r0 : 0
+
+                r1 : Machine type number
+
+                r2 : Physical address of tagged list in system RAM
+
+        b) Entry with a flattened device-tree block.  Firmware loads the
+        physical address of the flattened device tree block (dtb) into r2,
+        r1 is not used, but it is considered good practise to use a valid
+        machine number as described in Documentation/arm/Booting.
+
+                r0 : 0
+
+                r1 : Valid machine type number.  When using a device tree,
+                a single machine type number will often be assigned to
+                represent a class or family of SoCs.
+
+                r2 : physical pointer to the device-tree block
+                (defined in chapter II) in RAM.  Device tree can be located
+                anywhere in system RAM, but it should be aligned on a 64 bit
+                boundary.
+
+   The kernel will differentiate between ATAGS and device tree booting by
+   reading the memory pointed to by r2 and looking for either the flattened
+   device tree block magic value (0xd00dfeed) or the ATAG_CORE value at
+   offset 0x4 from r2 (0x54410001).

+			DMA Engine API Guide
+			====================
+
+		 Vinod Koul <vinod dot koul at intel.com>
+
+NOTE: For DMA Engine usage in async_tx please see:
+	Documentation/crypto/async-tx-api.txt
+
+
+Below is a guide to device driver writers on how to use the Slave-DMA API of the
+DMA Engine. This is applicable only for slave DMA usage only.
+
+The slave DMA usage consists of following steps
+1. Allocate a DMA slave channel
+2. Set slave and controller specific parameters
+3. Get a descriptor for transaction
+4. Submit the transaction and wait for callback notification
+
+1. Allocate a DMA slave channel
+Channel allocation is slightly different in the slave DMA context, client
+drivers typically need a channel from a particular DMA controller only and even
+in some cases a specific channel is desired. To request a channel
+dma_request_channel() API is used.
+
+Interface:
+struct dma_chan *dma_request_channel(dma_cap_mask_t mask,
+		dma_filter_fn filter_fn,
+		void *filter_param);
+where dma_filter_fn is defined as:
+typedef bool (*dma_filter_fn)(struct dma_chan *chan, void *filter_param);
+
+When the optional 'filter_fn' parameter is set to NULL dma_request_channel
+simply returns the first channel that satisfies the capability mask.  Otherwise,
+when the mask parameter is insufficient for specifying the necessary channel,
+the filter_fn routine can be used to disposition the available channels in the
+system. The filter_fn routine is called once for each free channel in the
+system.  Upon seeing a suitable channel filter_fn returns DMA_ACK which flags
+that channel to be the return value from dma_request_channel.  A channel
+allocated via this interface is exclusive to the caller, until
+dma_release_channel() is called.
+
+2. Set slave and controller specific parameters
+Next step is always to pass some specific information to the DMA driver. Most of
+the generic information which a slave DMA can use is in struct dma_slave_config.
+It allows the clients to specify DMA direction, DMA addresses, bus widths, DMA
+burst lengths etc. If some DMA controllers have more parameters to be sent then
+they should try to embed struct dma_slave_config in their controller specific
+structure. That gives flexibility to client to pass more parameters, if
+required.
+
+Interface:
+int dmaengine_slave_config(struct dma_chan *chan,
+					  struct dma_slave_config *config)
+
+3. Get a descriptor for transaction
+For slave usage the various modes of slave transfers supported by the
+DMA-engine are:
+slave_sg	- DMA a list of scatter gather buffers from/to a peripheral
+dma_cyclic	- Perform a cyclic DMA operation from/to a peripheral till the
+		  operation is explicitly stopped.
+The non NULL return of this transfer API represents a "descriptor" for the given
+transaction.
+
+Interface:
+struct dma_async_tx_descriptor *(*chan->device->device_prep_dma_sg)(
+		struct dma_chan *chan,
+		struct scatterlist *dst_sg, unsigned int dst_nents,
+		struct scatterlist *src_sg, unsigned int src_nents,
+		unsigned long flags);
+struct dma_async_tx_descriptor *(*chan->device->device_prep_dma_cyclic)(
+		struct dma_chan *chan, dma_addr_t buf_addr, size_t buf_len,
+		size_t period_len, enum dma_data_direction direction);
+
+4. Submit the transaction and wait for callback notification
+To schedule the transaction to be scheduled by dma device, the "descriptor"
+returned in above (3) needs to be submitted.
+To tell the dma driver that a transaction is ready to be serviced, the
+descriptor->submit() callback needs to be invoked. This chains the descriptor to
+the pending queue.
+The transactions in the pending queue can be activated by calling the
+issue_pending API. If channel is idle then the first transaction in queue is
+started and subsequent ones queued up.
+On completion of the DMA operation the next in queue is submitted and a tasklet
+triggered. The tasklet would then call the client driver completion callback
+routine for notification, if set.
+Interface:
+void dma_async_issue_pending(struct dma_chan *chan);
+
+==============================================================================
+
+Additional usage notes for dma driver writers
+1/ Although DMA engine specifies that completion callback routines cannot submit
+any new operations, but typically for slave DMA subsequent transaction may not
+be available for submit prior to callback routine being called. This requirement
+is not a requirement for DMA-slave devices. But they should take care to drop
+the spin-lock they might be holding before calling the callback routine

-Acer Laptop WMI Extras Driver
-http://code.google.com/p/aceracpi
-Version 0.3
-4th April 2009
-
-Copyright 2007-2009 Carlos Corbacho <carlos@strangeworlds.co.uk>
-
-acer-wmi is a driver to allow you to control various parts of your Acer laptop
-hardware under Linux which are exposed via ACPI-WMI.
-
-This driver completely replaces the old out-of-tree acer_acpi, which I am
-currently maintaining for bug fixes only on pre-2.6.25 kernels. All development
-work is now focused solely on acer-wmi.
-
-Disclaimer
-**********
-
-Acer and Wistron have provided nothing towards the development acer_acpi or
-acer-wmi. All information we have has been through the efforts of the developers
-and the users to discover as much as possible about the hardware.
-
-As such, I do warn that this could break your hardware - this is extremely
-unlikely of course, but please bear this in mind.
-
-Background
-**********
-
-acer-wmi is derived from acer_acpi, originally developed by Mark
-Smith in 2005, then taken over by Carlos Corbacho in 2007, in order to activate
-the wireless LAN card under a 64-bit version of Linux, as acerhk[1] (the
-previous solution to the problem) relied on making 32 bit BIOS calls which are
-not possible in kernel space from a 64 bit OS.
-
-[1] acerhk: http://www.cakey.de/acerhk/
-
-Supported Hardware
-******************
-
-NOTE: The Acer Aspire One is not supported hardware. It cannot work with
-acer-wmi until Acer fix their ACPI-WMI implementation on them, so has been
-blacklisted until that happens.
-
-Please see the website for the current list of known working hardware:
-
-http://code.google.com/p/aceracpi/wiki/SupportedHardware
-
-If your laptop is not listed, or listed as unknown, and works with acer-wmi,
-please contact me with a copy of the DSDT.
-
-If your Acer laptop doesn't work with acer-wmi, I would also like to see the
-DSDT.
-
-To send me the DSDT, as root/sudo:
-
-cat /sys/firmware/acpi/tables/DSDT > dsdt
-
-And send me the resulting 'dsdt' file.
-
-Usage
-*****
-
-On Acer laptops, acer-wmi should already be autoloaded based on DMI matching.
-For non-Acer laptops, until WMI based autoloading support is added, you will
-need to manually load acer-wmi.
-
-acer-wmi creates /sys/devices/platform/acer-wmi, and fills it with various
-files whose usage is detailed below, which enables you to control some of the
-following (varies between models):
-
-* the wireless LAN card radio
-* inbuilt Bluetooth adapter
-* inbuilt 3G card
-* mail LED of your laptop
-* brightness of the LCD panel
-
-Wireless
-********
-
-With regards to wireless, all acer-wmi does is enable the radio on the card. It
-is not responsible for the wireless LED - once the radio is enabled, this is
-down to the wireless driver for your card. So the behaviour of the wireless LED,
-once you enable the radio, will depend on your hardware and driver combination.
-
-e.g. With the BCM4318 on the Acer Aspire 5020 series:
-
-ndiswrapper: Light blinks on when transmitting
-b43: Solid light, blinks off when transmitting
-
-Wireless radio control is unconditionally enabled - all Acer laptops that support
-acer-wmi come with built-in wireless. However, should you feel so inclined to
-ever wish to remove the card, or swap it out at some point, please get in touch
-with me, as we may well be able to gain some data on wireless card detection.
-
-The wireless radio is exposed through rfkill.
-
-Bluetooth
-*********
-
-For bluetooth, this is an internal USB dongle, so once enabled, you will get
-a USB device connection event, and a new USB device appears. When you disable
-bluetooth, you get the reverse - a USB device disconnect event, followed by the
-device disappearing again.
-
-Bluetooth is autodetected by acer-wmi, so if you do not have a bluetooth module
-installed in your laptop, this file won't exist (please be aware that it is
-quite common for Acer not to fit bluetooth to their laptops - so just because
-you have a bluetooth button on the laptop, doesn't mean that bluetooth is

-
-For the adventurously minded - if you want to buy an internal bluetooth
-module off the internet that is compatible with your laptop and fit it, then
-it will work just fine with acer-wmi.
-
-Bluetooth is exposed through rfkill.
-
-3G
-**
-
-3G is currently not autodetected, so the 'threeg' file is always created under
-sysfs. So far, no-one in possession of an Acer laptop with 3G built-in appears to
-have tried Linux, or reported back, so we don't have any information on this.
-
-If you have an Acer laptop that does have a 3G card in, please contact me so we
-can properly detect these, and find out a bit more about them.
-
-To read the status of the 3G card (0=off, 1=on):
-cat /sys/devices/platform/acer-wmi/threeg
-
-To enable the 3G card:
-echo 1 > /sys/devices/platform/acer-wmi/threeg
-
-To disable the 3G card:
-echo 0 > /sys/devices/platform/acer-wmi/threeg
-
-To set the state of the 3G card when loading acer-wmi, pass:
-threeg=X (where X is 0 or 1)
-
-Mail LED
-********
-
-This can be found in most older Acer laptops supported by acer-wmi, and many
-newer ones - it is built into the 'mail' button, and blinks when active.
-
-On newer (WMID) laptops though, we have no way of detecting the mail LED. If
-your laptop identifies itself in dmesg as a WMID model, then please try loading
-acer_acpi with:
-
-force_series=2490
-
-This will use a known alternative method of reading/ writing the mail LED. If
-it works, please report back to me with the DMI data from your laptop so this
-can be added to acer-wmi.
-
-The LED is exposed through the LED subsystem, and can be found in:
-
-/sys/devices/platform/acer-wmi/leds/acer-wmi::mail/
-
-The mail LED is autodetected, so if you don't have one, the LED device won't
-be registered.
-
-Backlight
-*********
-
-The backlight brightness control is available on all acer-wmi supported
-hardware. The maximum brightness level is usually 15, but on some newer laptops
-it's 10 (this is again autodetected).
-
-The backlight is exposed through the backlight subsystem, and can be found in:
-
-/sys/devices/platform/acer-wmi/backlight/acer-wmi/

+MOTIVATION
+
+Cleancache is a new optional feature provided by the VFS layer that
+potentially dramatically increases page cache effectiveness for
+many workloads in many environments at a negligible cost.
+
+Cleancache can be thought of as a page-granularity victim cache for clean
+pages that the kernel's pageframe replacement algorithm (PFRA) would like
+to keep around, but can't since there isn't enough memory.  So when the
+PFRA "evicts" a page, it first attempts to use cleancache code to
+put the data contained in that page into "transcendent memory", memory
+that is not directly accessible or addressable by the kernel and is
+of unknown and possibly time-varying size.
+
+Later, when a cleancache-enabled filesystem wishes to access a page
+in a file on disk, it first checks cleancache to see if it already
+contains it; if it does, the page of data is copied into the kernel
+and a disk access is avoided.
+
+Transcendent memory "drivers" for cleancache are currently implemented
+in Xen (using hypervisor memory) and zcache (using in-kernel compressed
+memory) and other implementations are in development.
+
+FAQs are included below.
+
+IMPLEMENTATION OVERVIEW
+
+A cleancache "backend" that provides transcendent memory registers itself
+to the kernel's cleancache "frontend" by calling cleancache_register_ops,
+passing a pointer to a cleancache_ops structure with funcs set appropriately.
+Note that cleancache_register_ops returns the previous settings so that
+chaining can be performed if desired. The functions provided must conform to
+certain semantics as follows:
+
+Most important, cleancache is "ephemeral".  Pages which are copied into
+cleancache have an indefinite lifetime which is completely unknowable
+by the kernel and so may or may not still be in cleancache at any later time.
+Thus, as its name implies, cleancache is not suitable for dirty pages.
+Cleancache has complete discretion over what pages to preserve and what
+pages to discard and when.
+
+Mounting a cleancache-enabled filesystem should call "init_fs" to obtain a
+pool id which, if positive, must be saved in the filesystem's superblock;
+a negative return value indicates failure.  A "put_page" will copy a
+(presumably about-to-be-evicted) page into cleancache and associate it with
+the pool id, a file key, and a page index into the file.  (The combination
+of a pool id, a file key, and an index is sometimes called a "handle".)
+A "get_page" will copy the page, if found, from cleancache into kernel memory.
+A "flush_page" will ensure the page no longer is present in cleancache;
+a "flush_inode" will flush all pages associated with the specified file;
+and, when a filesystem is unmounted, a "flush_fs" will flush all pages in
+all files specified by the given pool id and also surrender the pool id.
+
+An "init_shared_fs", like init_fs, obtains a pool id but tells cleancache
+to treat the pool as shared using a 128-bit UUID as a key.  On systems
+that may run multiple kernels (such as hard partitioned or virtualized
+systems) that may share a clustered filesystem, and where cleancache
+may be shared among those kernels, calls to init_shared_fs that specify the
+same UUID will receive the same pool id, thus allowing the pages to
+be shared.  Note that any security requirements must be imposed outside
+of the kernel (e.g. by "tools" that control cleancache).  Or a
+cleancache implementation can simply disable shared_init by always
+returning a negative value.
+
+If a get_page is successful on a non-shared pool, the page is flushed (thus
+making cleancache an "exclusive" cache).  On a shared pool, the page
+is NOT flushed on a successful get_page so that it remains accessible to
+other sharers.  The kernel is responsible for ensuring coherency between
+cleancache (shared or not), the page cache, and the filesystem, using
+cleancache flush operations as required.
+
+Note that cleancache must enforce put-put-get coherency and get-get
+coherency.  For the former, if two puts are made to the same handle but
+with different data, say AAA by the first put and BBB by the second, a
+subsequent get can never return the stale data (AAA).  For get-get coherency,
+if a get for a given handle fails, subsequent gets for that handle will
+never succeed unless preceded by a successful put with that handle.
+
+Last, cleancache provides no SMP serialization guarantees; if two
+different Linux threads are simultaneously putting and flushing a page
+with the same handle, the results are indeterminate.  Callers must
+lock the page to ensure serial behavior.
+
+CLEANCACHE PERFORMANCE METRICS
+
+Cleancache monitoring is done by sysfs files in the
+/sys/kernel/mm/cleancache directory.  The effectiveness of cleancache

+FAQ
+
+1) Where's the value? (Andrew Morton)
+
+Cleancache provides a significant performance benefit to many workloads
+in many environments with negligible overhead by improving the
+effectiveness of the pagecache.  Clean pagecache pages are
+saved in transcendent memory (RAM that is otherwise not directly
+addressable to the kernel); fetching those pages later avoids "refaults"
+and thus disk reads.
+
+Cleancache (and its sister code "frontswap") provide interfaces for
+this transcendent memory (aka "tmem"), which conceptually lies between
+fast kernel-directly-addressable RAM and slower DMA/asynchronous devices.
+Disallowing direct kernel or userland reads/writes to tmem
+is ideal when data is transformed to a different form and size (such
+as with compression) or secretly moved (as might be useful for write-
+balancing for some RAM-like devices).  Evicted page-cache pages (and
+swap pages) are a great use for this kind of slower-than-RAM-but-much-
+faster-than-disk transcendent memory, and the cleancache (and frontswap)
+"page-object-oriented" specification provides a nice way to read and
+write -- and indirectly "name" -- the pages.
+
+In the virtual case, the whole point of virtualization is to statistically
+multiplex physical resources across the varying demands of multiple
+virtual machines.  This is really hard to do with RAM and efforts to
+do it well with no kernel change have essentially failed (except in some
+well-publicized special-case workloads).  Cleancache -- and frontswap --
+with a fairly small impact on the kernel, provide a huge amount
+of flexibility for more dynamic, flexible RAM multiplexing.
+Specifically, the Xen Transcendent Memory backend allows otherwise
+"fallow" hypervisor-owned RAM to not only be "time-shared" between multiple
+virtual machines, but the pages can be compressed and deduplicated to
+optimize RAM utilization.  And when guest OS's are induced to surrender
+underutilized RAM (e.g. with "self-ballooning"), page cache pages
+are the first to go, and cleancache allows those pages to be
+saved and reclaimed if overall host system memory conditions allow.
+
+And the identical interface used for cleancache can be used in
+physical systems as well.  The zcache driver acts as a memory-hungry
+device that stores pages of data in a compressed state.  And
+the proposed "RAMster" driver shares RAM across multiple physical
+systems.
+
+2) Why does cleancache have its sticky fingers so deep inside the
+   filesystems and VFS? (Andrew Morton and Christoph Hellwig)
+
+The core hooks for cleancache in VFS are in most cases a single line
+and the minimum set are placed precisely where needed to maintain
+coherency (via cleancache_flush operations) between cleancache,
+the page cache, and disk.  All hooks compile into nothingness if
+cleancache is config'ed off and turn into a function-pointer-
+compare-to-NULL if config'ed on but no backend claims the ops
+functions, or to a compare-struct-element-to-negative if a
+backend claims the ops functions but a filesystem doesn't enable
+cleancache.
+
+Some filesystems are built entirely on top of VFS and the hooks
+in VFS are sufficient, so don't require an "init_fs" hook; the
+initial implementation of cleancache didn't provide this hook.
+But for some filesystems (such as btrfs), the VFS hooks are
+incomplete and one or more hooks in fs-specific code are required.
+And for some other filesystems, such as tmpfs, cleancache may
+be counterproductive.  So it seemed prudent to require a filesystem
+to "opt in" to use cleancache, which requires adding a hook in
+each filesystem.  Not all filesystems are supported by cleancache
+only because they haven't been tested.  The existing set should
+be sufficient to validate the concept, the opt-in approach means
+that untested filesystems are not affected, and the hooks in the
+existing filesystems should make it very easy to add more
+filesystems in the future.
+
+The total impact of the hooks to existing fs and mm files is only
+about 40 lines added (not counting comments and blank lines).
+
+3) Why not make cleancache asynchronous and batched so it can
+   more easily interface with real devices with DMA instead
+   of copying each individual page? (Minchan Kim)
+
+The one-page-at-a-time copy semantics simplifies the implementation
+on both the frontend and backend and also allows the backend to
+do fancy things on-the-fly like page compression and
+page deduplication.  And since the data is "gone" (copied into/out
+of the pageframe) before the cleancache get/put call returns,
+a great deal of race conditions and potential coherency issues
+are avoided.  While the interface seems odd for a "real device"
+or for real kernel-addressable RAM, it makes perfect sense for
+transcendent memory.
+
+4) Why is non-shared cleancache "exclusive"?  And where is the
+   page "flushed" after a "get"? (Minchan Kim)
+
+The main reason is to free up space in transcendent memory and
+to avoid unnecessary cleancache_flush calls.  If you want inclusive,
+the page can be "put" immediately following the "get".  If
+put-after-get for inclusive becomes common, the interface could
+be easily extended to add a "get_no_flush" call.
+
+The flush is done by the cleancache backend implementation.
+
+5) What's the performance impact?
+
+Performance analysis has been presented at OLS'09 and LCA'10.
+Briefly, performance gains can be significant on most workloads,
+especially when memory pressure is high (e.g. when RAM is
+overcommitted in a virtual workload); and because the hooks are
+invoked primarily in place of or in addition to a disk read/write,
+overhead is negligible even in worst case workloads.  Basically
+cleancache replaces I/O with memory-copy-CPU-overhead; on older
+single-core systems with slow memory-copy speeds, cleancache
+has little value, but in newer multicore machines, especially
+consolidated/virtualized machines, it has great value.
+
+6) How do I add cleancache support for filesystem X? (Boaz Harrash)
+
+Filesystems that are well-behaved and conform to certain
+restrictions can utilize cleancache simply by making a call to
+cleancache_init_fs at mount time.  Unusual, misbehaving, or
+poorly layered filesystems must either add additional hooks
+and/or undergo extensive additional testing... or should just
+not enable the optional cleancache.
+
+Some points for a filesystem to consider:
+
+- The FS should be block-device-based (e.g. a ram-based FS such
+  as tmpfs should not enable cleancache)
+- To ensure coherency/correctness, the FS must ensure that all
+  file removal or truncation operations either go through VFS or
+  add hooks to do the equivalent cleancache "flush" operations
+- To ensure coherency/correctness, either inode numbers must
+  be unique across the lifetime of the on-disk file OR the
+  FS must provide an "encode_fh" function.
+- The FS must call the VFS superblock alloc and deactivate routines
+  or add hooks to do the equivalent cleancache calls done there.
+- To maximize performance, all pages fetched from the FS should
+  go through the do_mpag_readpage routine or the FS should add
+  hooks to do the equivalent (cf. btrfs)
+- Currently, the FS blocksize must be the same as PAGESIZE.  This
+  is not an architectural restriction, but no backends currently
+  support anything different.
+- A clustered FS should invoke the "shared_init_fs" cleancache
+  hook to get best performance for some backends.
+
+7) Why not use the KVA of the inode as the key? (Christoph Hellwig)
+
+If cleancache would use the inode virtual address instead of
+inode/filehandle, the pool id could be eliminated.  But, this
+won't work because cleancache retains pagecache data pages
+persistently even when the inode has been pruned from the
+inode unused list, and only flushes the data page if the file
+gets removed/truncated.  So if cleancache used the inode kva,
+there would be potential coherency issues if/when the inode
+kva is reused for a different file.  Alternately, if cleancache
+flushed the pages when the inode kva was freed, much of the value
+of cleancache would be lost because the cache of pages in cleanache
+is potentially much larger than the kernel pagecache and is most
+useful if the pages survive inode cache removal.
+
+8) Why is a global variable required?
+
+The cleancache_enabled flag is checked in all of the frequently-used
+cleancache hooks.  The alternative is a function call to check a static
+variable. Since cleancache is enabled dynamically at runtime, systems
+that don't enable cleancache would suffer thousands (possibly
+tens-of-thousands) of unnecessary function calls per second.  So the
+global variable allows cleancache to be enabled by default at compile
+time, but have insignificant performance impact when cleancache remains
+disabled at runtime.
+
+9) Does cleanache work with KVM?
+
+The memory model of KVM is sufficiently different that a cleancache
+backend may have less value for KVM.  This remains to be tested,
+especially in an overcommitted system.
+
+10) Does cleancache work in userspace?  It sounds useful for
+   memory hungry caches like web browsers.  (Jamie Lokier)
+
+No plans yet, though we agree it sounds useful, at least for
+apps that bypass the page cache (e.g. O_DIRECT).
