2012-03-30Documentation: replace install commands with softdepsLucas De Marchi
Install commands should not be used to specify soft dependencies among modules. When loading modules it's much better to have a softdep that modprobe knows what's being done than having to fork/exec another instance of modprobe to load the other module. By using a softdep user has also an option to remove the dependencies when removing the module (and if its refcount dropped to 0) Signed-off-by: Lucas De Marchi <lucas.demarchi@profusion.mobi> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-03-30ACPI throttling: fix endian bug in acpi_read_throttling_status()Dan Carpenter
Using a u64 here creates an endian bug. We store a u32 number in the top byte which is a larger number than intended on big endian systems. There is no reason to use a 64 bit data type here, I guess it was just an oversight. I removed the initialization to zero as well. It's needed with a u64 but with a u32, the variable gets initialized properly inside the call to acpi_os_read_port().

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs Pull btrfs fixes and features from Chris Mason: "We've merged in the error handling patches from SuSE. These are already shipping in the sles kernel, and they give btrfs the ability to abort transactions and go readonly on errors. It involves a lot of churn as they clarify BUG_ONs, and remove the ones we now properly deal with. Josef reworked the way our metadata interacts with the page cache. page->private now points to the btrfs extent_buffer object, which makes everything faster. He changed it so we write an whole extent buffer at a time instead of allowing individual pages to go down,, which will be important for the raid5/6 code (for the 3.5 merge window ;) Josef also made us more aggressive about dropping pages for metadata blocks that were freed due to COW. Overall, our metadata caching is much faster now. We've integrated my patch for metadata bigger than the page size. This allows metadata blocks up to 64KB in size. In practice 16K and 32K seem to work best. For workloads with lots of metadata, this cuts down the size of the extent allocation tree dramatically and fragments much less. Scrub was updated to support the larger block sizes, which ended up being a fairly large change (thanks Stefan Behrens). We also have an assortment of fixes and updates, especially to the balancing code (Ilya Dryomov), the back ref walker (Jan Schmidt) and the defragging code (Liu Bo)."

The acpi_processor_cst_has_changed() function is invoked from a CPU_ONLINE or CPU_DEAD function, which might well execute on CPU 0 even though the CPU being hotplugged is some other CPU. In addition, acpi_processor_cst_has_changed() invokes smp_processor_id() without protection, resulting in splats when onlining CPUs.

2012-03-30ACPI: Fix use-after-free in acpi_map_lsapicPetr Vandrovec
When processor is being hot-added to the system, acpi_map_lsapic invokes ACPI _MAT method to find APIC ID and flags, verifies that returned structure is indeed ACPI's local APIC structure, and that flags contain MADT_ENABLED bit. Then saves APIC ID, frees structure - and accesses structure when computing arguments for acpi_register_lapic call. Which sometime leads to acpi_register_lapic call being made with second argument zero, failing to bring processor online with error 'Unable to map lapic to logical cpu number'. As lapic->lapic_flags & ACPI_MADT_ENABLED was already confirmed to be non-zero few lines above, we can just pass unconditional ACPI_MADT_ENABLED to the acpi_register_lapic.

The function acpi_processor_add is stored in the ops.add field of a acpi_driver structure. This function is then called in acpi_bus_driver_init. On failure, this function clears the field device->driver_data, but does not free its contents. Thus the free has to be done by the add function. In acpi_processor_add, the corresponding value is pr. This value is currently freed on failure before storing it in device->driver_data, but not after. This free is added in the error handling code at the end of the function. The per_cpu variable processors is also cleared so that it does not refer to a dangling pointer. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Reviewed-by: Srivatsa S.

This fixes a trivial copy & paste error in ERST header length check. It's just for future safety because sizeof(struct acpi_table_einj) equals to sizeof(struct acpi_table_erst) with current ACPI5.0 specification. It applies to v3.3-rc6.

2012-03-30idle, x86: Allow off-lined CPU to enter deeper C statesBoris Ostrovsky
Currently when a CPU is off-lined it enters either MWAIT-based idle or, if MWAIT is not desired or supported, HLT-based idle (which places the processor in C1 state). This patch allows processors without MWAIT support to stay in states deeper than C1. Signed-off-by: Boris Ostrovsky <boris.ostrovsky@amd.com> Signed-off-by: Len Brown <len.brown@intel.com>

2012-03-30ACPI: Add CPU hotplug support for processor device objectsToshi Kani
acpi_processor_install_hotplug_notify() registers processor objects to receive ACPI CPU hotplug event notifications. This patch additionally registers processor device objects (ACPI0007) to receive the notifications as well.

2012-03-30ACPI: Evaluate thermal trip points before reading temperatureMatthew Garrett
An HP laptop (Pavilion G4-1016tx) has the following code in _TMP: Store (\_SB.PCI0.LPCB.EC0.RTMP, Local0) If (LGreaterEqual (Local0, S4TP)) { Store (One, HTS4) } S4TP is initialised at 0 and not programmed further until either _HOT or _CRT is called. If we evaluate _TMP before the trip points then HTS4 will always be set, causing the firmware to generate a message on boot complaining that the system shut down because of overheating. The simplest solution is just to reverse the checking of trip points and _TMP in thermal init. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Len Brown <len.brown@intel.com>
2012-03-30ACPI, PCI: Move acpi_dev_run_wake() to ACPI coreLin Ming
acpi_dev_run_wake() is a generic function which can be used by other subsystem too. Rename it to acpi_pm_device_run_wake, to be consistent with acpi_pm_device_sleep_wake. Then move it to ACPI core.
