We handle the S4 case with exactly the same scenario, so just point the suspend/resume routines to the freeze/restore ones. Once that is done, we also use the PM API's macro to initialise the sleep functions. A couple of cleanups are included: there's no need for special thaw processing in the balloon driver, so that's addressed in patches 1 and 2. Testing: both S3 and S4 support have been tested using these patches using a similar method used earlier during S4 patch development: a guest is started with virtio-blk as the only disk, a virtio network card, a virtio-serial port and a virtio balloon device. Ping from guest to host, dd /dev/zero to a file on the disk, and IO from the host on the virtio-serial port, all at once, while exercising S4 and S3 (separately) were tested. They all continue to work fine after resume. virtio balloon values too were tested by inflating and deflating the balloon." Pulling from Amit, since Rusty is off getting married (and presumably shaving people). * 's3-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/amit/virtio-console: virtio-pci: switch to PM ops macro to initialise PM functions virtio-pci: S3 support virtio-pci: drop restore_common() virtio: drop thaw PM operation virtio: balloon: Allow stats update after restore from S4 31 March 2012, 22:11:39 UTC

c9651e7 Matthew Garrett 27 March 2012, 14:17:41 UTC ASPM: Fix pcie devices with non-pcie children Since 3.2.12 and 3.3, some systems are failing to boot with a BUG_ON. Some other systems using the pata_jmicron driver fail to boot because no disks are detected. Passing pcie_aspm=force on the kernel command line works around it. The cause: commit 4949be16822e ("PCI: ignore pre-1.1 ASPM quirking when ASPM is disabled") changed the behaviour of pcie_aspm_sanity_check() to always return 0 if aspm is disabled, in order to avoid cases where we changed ASPM state on pre-PCIe 1.1 devices. This skipped the secondary function of pcie_aspm_sanity_check which was to avoid us enabling ASPM on devices that had non-PCIe children, causing trouble later on. Move the aspm_disabled check so we continue to honour that scenario.

cdb0f9a Linus Torvalds 31 March 2012, 18:12:57 UTC selinux: inline avc_audit() and avc_has_perm_noaudit() into caller Now that all the slow-path code is gone from these functions, we can inline them into the main caller - avc_has_perm_flags(). Now the compiler can see that 'avc' is allocated on the stack for this case, which helps register pressure a bit. It also actually shrinks the total stack frame, because the stack frame that avc_has_perm_flags() always needed (for that 'avc' allocation) is now sufficient for the inlined functions too. Inlining isn't bad - but mindless inlining of cold code (see the previous commit) is. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 31 March 2012, 18:24:22 UTC
a554bea Linus Torvalds 31 March 2012, 17:58:08 UTC selinux: don't inline slow-path code into avc_has_perm_noaudit() The selinux AVC paths remain some of the hottest (and deepest) codepaths at filename lookup time, and we make it worse by having the slow path cases take up I$ and stack space even when they don't trigger. Gcc tends to always want to inline functions that are just called once - never mind that this might make for slower and worse code in the caller. So this tries to improve on it a bit by making the slow-path cases explicitly separate functions that are marked noinline, causing gcc to at least no longer allocate stack space for them unless they are actually called. It also seems to help register allocation a tiny bit, since gcc now doesn't take the slow case code into account. Uninlining the slow path may also allow us to inline the remaining hot path into the one caller that actually matters: avc_has_perm_flags(). I'll have to look at that separately, but both avc_audit() and avc_has_perm_noaudit() are now small and lean enough that inlining them may make sense.

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)."

In addition, acpi_processor_cst_has_changed() invokes smp_processor_id() without protection, resulting in splats when onlining CPUs.

ac909ec Petr Vandrovec 08 March 2012, 21:33:24 UTC ACPI: Fix use-after-free in acpi_map_lsapic 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.

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.
