commit e63ed0d7a98014fdfc2cfeb3f6dada313dcabb59 upstream.
This patch eliminates the reap_ref and replaces it with a proper kref.
On last put of this kref, the target is removed from visibility in
sysfs. The final call to scsi_target_reap() for the device is done from
__scsi_remove_device() and only if the device was made visible. This
ensures that the target disappears as soon as the last device is gone
rather than waiting until final release of the device (which is often
too long).

commit 008208c6b26f21c2648c250a09c55e737c02c5f8 upstream.
Add two trivial helpers list_next_entry() and list_prev_entry(), they
can have a lot of users including list.h itself. In fact the 1st one is
already defined in events/core.c and bnx2x_sp.c, so the patch simply
moves the definition to list.h.

commit 624966589041deb32a2626ee2e176e8274581101 upstream.
Mode setting in the TGA driver is broken for these reasons:
- info->fix.line_length is set just once in tgafb_init_fix function. If
we change videomode, info->fix.line_length is not recalculated - so
the video mode is changed but the screen is corrupted because of wrong
info->fix.line_length.
- info->fix.smem_len is set in tgafb_init_fix to the size of the default
video mode (640x480). If we set a higher resolution,
info->fix.smem_len is smaller than the current screen size, preventing
the userspace program from mapping the framebuffer.
This patch fixes it:
- info->fix.line_length initialization is moved to tgafb_set_par so that
it is recalculated with each mode change.
- info->fix.smem_len is set to a fixed value representing the real
amount of video ram (the values are taken from xfree86 driver).
- add a check to tgafb_check_var to prevent us from setting a videomode
that doesn't fit into videoram.
- in tgafb_register, tgafb_init_fix is moved upwards, to be called
before fb_find_mode (because fb_find_mode already needs the videoram
size set in tgafb_init_fix).

and X1
commit 46a2986ebbe18757c2d8c352f8fb6e0f4f0754e3 upstream.
We expect that all the Haswell series will need such quirks, sigh.
The T431s seems to be T430 hardware in a T440s case, using the T440s touchpad,
with the same min/max issue.
The X1 Carbon 3rd generation name says 2nd while it is a 3rd generation.
The X1 and T431s share a PnPID with the T540p, but the reported ranges are
closer to those of the T440s.
HdG: Squashed 5 quirk patches into one. T431s + L440 + L540 are written by me,
S1 Yoga and X1 are written by Benjamin Tissoires.
Hdg: Standardized S1 Yoga and X1 values, Yoga uses the same touchpad as the
X240, X1 uses the same touchpad as the T440.

commit 5fc68a6cad658e45dca3e0a6607df3a8e5df4ef9 upstream.
The code to handle any length SG lists calls edma_resume()
even before edma_start() is called. This is incorrect
because edma_resume() enables edma events on the channel
after which CPU (in edma_start) cannot clear posted
events by writing to ECR (per the EDMA user's guide).
Because of this EDMA transfers fail to start if due
to some reason there is a pending EDMA event registered
even before EDMA transfers are started. This can happen if
an EDMA event is a byproduct of device initialization.
Fix this by calling edma_resume() only if it is not the
first batch of MAX_NR_SG elements.
Without this patch, MMC/SD fails to function on DA850 EVM
with DMA. The behaviour is triggered by specific IP and
this can explain why the issue was not reported before
(example with MMC/SD on AM335x).
Tested on DA850 EVM and AM335x EVM-SK using MMC/SD card.

commit a9d45396f5956d0b615c7ae3b936afd888351a47 upstream.
The persistent-data library used by dm-thin, dm-cache, etc is
transactional. If anything goes wrong, such as an io error when writing
new metadata or a power failure, then we roll back to the last
transaction.
Atomicity when committing a transaction is achieved by:
a) Never overwriting data from the previous transaction.
b) Writing the superblock last, after all other metadata has hit the
disk.
This commit and the following commit ("dm: take care to copy the space
map roots before locking the superblock") fix a bug associated with (b).
When committing it was possible for the superblock to still be written
in spite of an io error occurring during the preceeding metadata flush.
With these commits we're careful not to take the write lock out on the
superblock until after the metadata flush has completed.
Change the transaction manager's semantics for dm_tm_commit() to assume
all data has been flushed _before_ the single superblock that is passed
in.
As a prerequisite, split the block manager's block unlocking and
flushing by simplifying dm_bm_flush_and_unlock() to dm_bm_flush(). Now
the unlocking must be done separately.
This issue was discovered by forcing io errors at the crucial time
using dm-flakey.

commit d132cc6d9e92424bb9d4fd35f5bd0e55d583f4be upstream.
If the discard block size is larger than the cache block size we will
not properly quiesce IO to a region that is about to be discarded. This
results in a race between a cache migration where no copy is needed, and
a write to an adjacent cache block that's within the same large discard
block.
Workaround this by limiting the discard_block_size to cache_block_size.
Also limit the max_discard_sectors to cache_block_size.
A more comprehensive fix that introduces range locking support in the
bio_prison and proper quiescing of a discard range that spans multiple
cache blocks is already in development.

commit 6b0df6827bb6fcacb158dff29ad0a62d6418b534 upstream.
The functions for data copying copyarea_foreward_8bpp and
copyarea_backward_8bpp are buggy, they produce screen corruption.
This patch fixes the functions and moves the logic to one function
"copyarea_8bpp". For simplicity, the function only handles copying that
is aligned on 8 pixes. If we copy an unaligned area, generic function
cfb_copyarea is used.

commit a585f87c863e4e1d496459d382b802bf5ebe3717 upstream.
The scenario here is that someone calls enable_irq_wake() from somewhere
in the code. This will result in the lockdep producing a backtrace as can
be seen below. In my case, this problem is triggered when using the wl1271
(TI WlCore) driver found in drivers/net/wireless/ti/ .
The problem cause is rather obvious from the backtrace, but let's outline
the dependency. enable_irq_wake() grabs the IRQ buslock in irq_set_irq_wake(),
which in turns calls mxs_gpio_set_wake_irq() . But mxs_gpio_set_wake_irq()
calls enable_irq_wake() again on the one-level-higher IRQ , thus it tries to
grab the IRQ buslock again in irq_set_irq_wake() . Because the spinlock in
irq_set_irq_wake()->irq_get_desc_buslock()->__irq_get_desc_lock() is not
marked as recursive, lockdep will spew the stuff below.
We know we can safely re-enter the lock, so use IRQ_GC_INIT_NESTED_LOCK to
fix the spew.

commit 3b3e0efb5c72c4fc940af50b33626b8a78a907dc upstream.
qi->tqi_readyTime is written directly to registers that expect
microseconds as unit instead of TU.
When setting the CABQ ready time, cur_conf->beacon_interval is in TU, so
convert it to microseconds before passing it to ath9k_hw.
This should hopefully fix some Tx DMA issues with buffered multicast
frames in AP mode.

commit d121f7d0cbb875abce249dbf7eb191f9bafe80b7 upstream.
Crucial/Micron M500 drives properly support queued DSM TRIM starting
with firmware MU05. Update the blacklist so we only disable queued trim
for older firmware releases.
Early M550 series drives suffer from the same issue as M500. A bugfix
firmware is in the pipeline but not ready yet. Until then, blacklist
queued trim for M550.

commit 2cf532f5e67c0cfe38c8c100e49280cdadacd2be upstream.
In multiple MSI mode all AHCI ports (including dummy) get assigned
separate MSI vectors and (as result of execution
pci_enable_msi_exact() function) separate IRQ numbers, (mapped to the
MSI vectors).
Therefore, although interrupts from dummy ports are not desired they
are still enabled. We do not request IRQs for dummy ports, but that
only means we do not assign AHCI-specific ISRs to corresponding IRQ
numbers.
As result, dummy port interrupts still could come and traverse all the
way from the PCI device to the kernel, causing unnecessary overhead.
This update disables IRQs for dummy ports and prevents the described
issue.

commit 8a4aeec8d2d6a3edeffbdfae451cdf05cbf0fefd upstream.
The AHCI spec allows implementations to issue commands in tag order
rather than FIFO order:
5.3.2.12 P:SelectCmd
HBA sets pSlotLoc = (pSlotLoc + 1) mod (CAP.NCS + 1)
or HBA selects the command to issue that has had the
PxCI bit set to '1' longer than any other command
pending to be issued.
The result is that commands posted sequentially (time-wise) may play out
of sequence when issued by hardware.
This behavior has likely been hidden by drives that arrange for commands
to complete in issue order. However, it appears recent drives (two from
different vendors that we have found so far) inflict out-of-order
completions as a matter of course. So, we need to take care to maintain
ordered submission, otherwise we risk triggering a drive to fall out of
sequential-io automation and back to random-io processing, which incurs
large latency and degrades throughput.
This issue was found in simple benchmarks where QD=2 seq-write
performance was 30-50% *greater* than QD=32 seq-write performance.
Tagging for -stable and making the change globally since it has a low
risk-to-reward ratio. Also, word is that recent versions of an unnamed
OS also does it this way now. So, drives in the field are already
experienced with this tag ordering scheme.

commit cc6ca3023f2c2bbcd062e9d4cf6afc2ba2821ada upstream.
This reverts commit e3a8786c10e75903f1269474e21fe8cb49c3a670. While
this commit allows to use the mvneta driver as a module on some
configurations, it breaks other configurations even if mvneta is used
built-in.
This breakage is due to the fact that on some RGMII platforms, the PCS
bit has to be set, and on some other platforms, it has to be
cleared. At the moment, we lack informations to know exactly the
significance of this bit (the datasheet only says "enables PCS"), and
so we can't produce a patch that will work on all platforms at this
point. And since this change is breaking the network completely for
many users, it's much better to revert it for now. We'll come back
later with a proper fix that takes into account all platforms.
Basically:
* Armada XP GP is configured as RGMII-ID, and needs the PCS bit to be
set.
* Armada 370 Mirabox is configured as RGMII-ID, and needs the PCS bit
to be cleared.
And at the moment, we don't know how to make the distinction between
those two cases. One hint is that the Armada XP GP appears in fact to
be using a QSGMII connection with the PHY (Quad-SGMII), but
configuring it as SGMII doesn't work, while RGMII-ID works. This needs
more investigation, but in the mean time, let's unbreak the network
for all those users.

commit 43751a1b8ee2e70ce392bf31ef3133da324e68b3 upstream.
This patch fixes the hardware cursor on mach64 when font width is not a
multiple of 8 pixels.
If you load such a font, the cursor is expanded to the next 8-byte
boundary and a part of the next character after the cursor is not
visible.
For example, when you load a font with 12-pixel width, the cursor width
is 16 pixels and when the cursor is displayed, 4 pixels of the next
character are not visible.
The reason is this: atyfb_cursor is called with proper parameters to
load an image that is 12-pixel wide. However, the number is aligned on
the next 8-pixel boundary on the line
"unsigned int width = (cursor->image.width + 7) >> 3;" and the whole
function acts as it is was loading a 16-pixel image.
This patch fixes it so that the value written to the framebuffer is
padded with 0xaaaa (the transparent pattern) when the image size it not
a multiple of 8 pixels. The transparent pattern causes that the cursor
will not interfere with the next character.

commit c29dd8696dc5dbd50b3ac441b8a26751277ba520 upstream.
This patch fixes mach64 to use unaligned access to the font bitmap.
This fixes unaligned access warning on sparc64 when 14x8 font is loaded.
On x86(64), unaligned access is handled in hardware, so both functions
le32_to_cpup and get_unaligned_le32 perform the same operation.
On RISC machines, unaligned access is not handled in hardware, so we
better use get_unaligned_le32 to avoid the unaligned trap and warning.

commit 00a9d699bc85052d2d3ed56251cd928024ce06a3 upstream.
The function cfb_copyarea is buggy when the copy operation is not aligned on
long boundary (4 bytes on 32-bit machines, 8 bytes on 64-bit machines).
How to reproduce:
- use x86-64 machine
- use a framebuffer driver without acceleration (for example uvesafb)
- set the framebuffer to 8-bit depth
(for example fbset -a 1024x768-60 -depth 8)
- load a font with character width that is not a multiple of 8 pixels
note: the console-tools package cannot load a font that has
width different from 8 pixels. You need to install the packages
"kbd" and "console-terminus" and use the program "setfont" to
set font width (for example: setfont Uni2-Terminus20x10)
- move some text left and right on the bash command line and you get a
screen corruption
To expose more bugs, put this line to the end of uvesafb_init_info:
info->flags |= FBINFO_HWACCEL_COPYAREA | FBINFO_READS_FAST;
- Now framebuffer console will use cfb_copyarea for console scrolling.
You get a screen corruption when console is scrolled.
This patch is a rewrite of cfb_copyarea. It fixes the bugs, with this
patch, console scrolling in 8-bit depth with a font width that is not a
multiple of 8 pixels works fine.
The cfb_copyarea code was very buggy and it looks like it was written
and never tried with non-8-pixel font.

commit 06cd7a874ec6e09d151aeb1fa8600e14f1ff89f6 upstream.
Using a notification type mask for the store event information chsc
is unsupported on some firmware levels. Retry SEI with that mask set
to zero (which is the old way of requesting only channel subsystem
related events).

commit af61e27c3f77c7623b5335590ae24b6a5c323e22 upstream.
On suspend, _scsih_suspend calls mpt2sas_base_free_resources, which
in turn calls pci_disable_device if the device is enabled prior to
suspending. However, _scsih_suspend also calls pci_disable_device
itself.
Thus, in the event that the device is enabled prior to suspending,
pci_disable_device will be called twice. This patch removes the
duplicate call to pci_disable_device in _scsi_suspend as it is both
unnecessary and results in a kernel oops.

commit 0c8482ac92db5ac15792caf23b7f7df9e4f48ae1 upstream.
virtscsi_init calls virtscsi_remove_vqs on err, even before initializing
the vqs. The latter calls virtscsi_set_affinity, so let's check the
pointer there before setting affinity on it.
This fixes a panic when setting device's num_queues=2 on RHEL 6.5:
qemu-system-x86_64 ... \
-device virtio-scsi-pci,id=scsi0,addr=0x13,...,num_queues=2 \
-drive file=/stor/vm/dummy.raw,id=drive-scsi-disk,... \
-device scsi-hd,drive=drive-scsi-disk,...
