commit 764bcbc5 upstream. __kvm_set_xcr function does the CPL check when set xcr. __kvm_set_xcr is called in two flows, one is invoked by guest, call stack shown as below, handle_xsetbv(or xsetbv_interception) kvm_set_xcr __kvm_set_xcr the other one is invoked by host, for example during system reset: kvm_arch_vcpu_ioctl kvm_vcpu_ioctl_x86_set_xcrs __kvm_set_xcr The former does need the CPL check, but the latter does not.

commit 1bc39742 upstream. Commit f8b63c18 made flush_kernel_dcache_page a no-op assuming that the pages it needs to handle are kernel mapped only. However, for example when doing direct I/O, pages with user space mappings may occur. Thus, continue to do lazy flushing if there are no user space mappings. Otherwise, flush the kernel cache lines directly. Signed-off-by:

commit 342cda29 upstream. When the Android firmware enables the audio interfaces in accessory mode, it always declares in the control interface's baInterfaceNr array that interfaces 0 and 1 belong to the audio function. However, the accessory interface itself, if also enabled, already is at index 0 and shifts the actual audio interface numbers to 1 and 2, which prevents the PCM streaming interface from being seen by the host driver. To get the PCM interface interface to work, detect when the descriptors point to the (for this driver useless) accessory interface, and redirect to the correct one. Reported-by:

While this needs to be fixed in gcc, it's also easy to avoid having it cause build failures when building with those compilers by exporting __ffsdi2 to modules. Signed-off-by:

commit bf593907 upstream. Normally, the kernel emulates a few instructions that are unimplemented on some processors (e.g. the old dcba instruction), or privileged (e.g. mfpvr). The emulation of unimplemented instructions is currently not working on the PowerNV platform. The reason is that on these machines, unimplemented and illegal instructions cause a hypervisor emulation assist interrupt, rather than a program interrupt as on older CPUs. Our vector for the emulation assist interrupt just calls program_check_exception() directly, without setting the bit in SRR1 that indicates an illegal instruction interrupt. This fixes it by making the emulation assist interrupt set that bit before calling program_check_interrupt(). With this, old programs that use no-longer implemented instructions such as dcba now work again. Signed-off-by:

commit df465abf upstream. Some systems that don't need wake-on-lan may choose to power down the chip on system standby. Upon resume, the power on causes the boot code to startup and initialize the hardware. On one new platform, this is causing the device to go into a bad state due to a race between the driver and boot code, once every several hundred resumes. The same race exists on open since we come up from a power on. This patch adds a wait for boot code signature at the beginning of tg3_init_hw() which is common to both cases. If there has not been a power-off or the boot code has already completed, the signature will be present and poll_fw() returns immediately. Also return immediately if the device does not have firmware. Signed-off-by:

md/raid1: consider WRITE as successful only if at least one non-Faulty and non-rebuilding drive completed it. commit 3056e3ae upstream. Without that fix, the following scenario could happen: - RAID1 with drives A and B; drive B was freshly-added and is rebuilding - Drive A fails - WRITE request arrives to the array. It is failed by drive A, so r1_bio is marked as R1BIO_WriteError, but the rebuilding drive B succeeds in writing it, so the same r1_bio is marked as R1BIO_Uptodate. - r1_bio arrives to handle_write_finished, badblocks are disabled, md_error()->error() does nothing because we don't fail the last drive of raid1 - raid_end_bio_io() calls call_bio_endio() - As a result, in call_bio_endio(): if (!test_bit(R1BIO_Uptodate, &r1_bio->state)) clear_bit(BIO_UPTODATE, &bio->bi_flags); this code doesn't clear the BIO_UPTODATE flag, and the whole master WRITE succeeds, back to the upper layer. So we returned success to the upper layer, even though we had written the data onto the rebuilding drive only. But when we want to read the data back, we would not read from the rebuilding drive, so this data is lost. [neilb - applied identical change to raid10 as well] This bug can result in lost data, so it is suitable for any -stable kernel. Signed-off-by:

commit 30dad309 upstream. When we have a page fault for the address which is backed by a hugepage under migration, the kernel can't wait correctly and do busy looping on hugepage fault until the migration finishes. As a result, users who try to kick hugepage migration (via soft offlining, for example) occasionally experience long delay or soft lockup. This is because pte_offset_map_lock() can't get a correct migration entry or a correct page table lock for hugepage. This patch introduces migration_entry_wait_huge() to solve this. Signed-off-by:

commit cbab0e4e upstream. read_swap_cache_async() can race against get_swap_page(), and stumble across a SWAP_HAS_CACHE entry in the swap map whose page wasn't brought into the swapcache yet. This transient swap_map state is expected to be transitory, but the actual placement of discard at scan_swap_map() inserts a wait for I/O completion thus making the thread at read_swap_cache_async() to loop around its -EEXIST case, while the other end at get_swap_page() is scheduled away at scan_swap_map(). This can leave the system deadlocked if the I/O completion happens to be waiting on the CPU waitqueue where read_swap_cache_async() is busy looping and !CONFIG_PREEMPT. This patch introduces a cond_resched() call to make the aforementioned read_swap_cache_async() busy loop condition to bail out when necessary, thus avoiding the subtle race window. Signed-off-by:

commit 24b8256a upstream. When booted in legacy mode device_init_wakeup() gets called by drivers/mfd/twl-core.c when the children are initialized. However, when booted using device tree, the children are created with of_platform_populate() instead add_children(). This means that the RTC driver will not have device_init_wakeup() set, and we need to call it from the driver probe like RTC drivers typically do. Without this we cannot test PM wake-up events on omaps for cases where there may not be any physical wake-up event. Signed-off-by:

commit cf7df378 upstream. We recently noticed that reboot of a 1024 cpu machine takes approx 16 minutes of just stopping the cpus. The slowdown was tracked to commit f96972f2 ("kernel/sys.c: call disable_nonboot_cpus() in kernel_restart()"). The current implementation does all the work of hot removing the cpus before halting the system. We are switching to just migrating to the boot cpu and then continuing with shutdown/reboot. This also has the effect of not breaking x86's command line parameter for specifying the reboot cpu. Note, this code was shamelessly copied from arch/x86/kernel/reboot.c with bits removed pertaining to the reboot_cpu command line parameter. Signed-off-by:

commit 531671cb upstream. Almost all the DMA issues which have plagued ath9k (in station mode) for years are related to PS. Disabling PS usually "fixes" the user's connection stablility. Reports of DMA problems are still trickling in and are sitting in the kernel bugzilla. Until the PS code in ath9k is given a thorough review, disbale it by default. The slight increase in chip power consumption is a small price to pay for improved link stability. Signed-off-by:

commit cb3b3152 upstream. There has been code in place to check that the L2CAP length header matches the amount of data received, but many PDU handlers have not been checking that the data received actually matches that expected by the specific PDU. This patch adds passing the length header to the specific handler functions and ensures that those functions fail cleanly in the case of an incorrect amount of data. Signed-off-by:

commit c3456fb3 upstream. In commit 53d3b4d7 Author: Egbert Eich <eich@suse.de> Date: Tue Jun 4 17:13:21 2013 +0200 drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC Egbert Eich fixed a long-standing bug where we simply used a non-working i2c controller to read the EDID for SDVO-LVDS panels. Unfortunately some machines seem to not be able to cope with the mode provided in the EDID. Specifically they seem to not be able to cope with a 4x pixel mutliplier instead of a 2x one, which seems to have been worked around by slightly changing the panels native mode in the VBT so that the dotclock is just barely above 50MHz. Since it took forever to notice the breakage it's fairly safe to assume that at least for SDVO-LVDS panels the VBT contains fairly sane data. So just switch around the order and use VBT modes first. v2: Also add EDID modes just in case, and spell Egbert correctly. v3: Elaborate a bit more about what's going on on Chris' machine.

commit da94a829 upstream. In August 2012, Matthew Gretton-Dann checked a change into binutils labelled "Error on obsolete & warn on deprecated registers", apparently as part of ARMv8 support. Apparently, this was supposed to emit the message "Warning: This coprocessor register access is deprecated in ARMv8" when using certain mcr/mrc instructions and building for ARMv8. Unfortunately, the message that is actually emitted appears to be '(null)', which is less helpful in comparison. Even more unfortunately, this is biting us on every single kernel build with a new gas, because arch/arm/boot/compressed/head.S and some other files in that directory are built with -march=all since kernel commit 80cec14a "[ARM] Add -march=all to assembly file build in arch/arm/boot/compressed" back in v2.6.28. This patch reverts Russell's nice solution and instead marks the head.S file to be built for armv7-a, which fortunately lets us build all instructions in that file without warnings even on the broken binutils. Without this patch, building anything results in: arch/arm/boot/compressed/head.S: Assembler messages: arch/arm/boot/compressed/head.S:565: Warning: (null) arch/arm/boot/compressed/head.S:676: Warning: (null) arch/arm/boot/compressed/head.S:698: Warning: (null) arch/arm/boot/compressed/head.S:722: Warning: (null) arch/arm/boot/compressed/head.S:726: Warning: (null) arch/arm/boot/compressed/head.S:957: Warning: (null) arch/arm/boot/compressed/head.S:996: Warning: (null) arch/arm/boot/compressed/head.S:997: Warning: (null) arch/arm/boot/compressed/head.S:1027: Warning: (null) arch/arm/boot/compressed/head.S:1035: Warning: (null) arch/arm/boot/compressed/head.S:1046: Warning: (null) arch/arm/boot/compressed/head.S:1060: Warning: (null) arch/arm/boot/compressed/head.S:1092: Warning: (null) arch/arm/boot/compressed/head.S:1094: Warning: (null) arch/arm/boot/compressed/head.S:1095: Warning: (null) arch/arm/boot/compressed/head.S:1102: Warning: (null) arch/arm/boot/compressed/head.S:1134: Warning: (null) Signed-off-by:
