2014-10-22MIPS: tlbex: Properly fix HUGE TLB Refill exception handlerDavid Daney
In commit 8393c524a25609 (MIPS: tlbex: Fix a missing statement for HUGETLB), the TLB Refill handler was fixed so that non-OCTEON targets would work properly with huge pages. The change was incorrect in that it broke the OCTEON case. The problem is shown here: xxx0: df7a0000 ld k0,0(k1) . . . xxxc0: df610000 ld at,0(k1) xxxc4: 335a0ff0 andi k0,k0,0xff0 xxxc8: e825ffcd bbit1 at,0x5,0x0 xxxcc: 003ad82d daddu k1,at,k0 . . . In the non-octeon case there is a destructive test for the huge PTE bit, and then at 0, $k0 is reloaded (that is what the 8393c524a25609 patch added). In the octeon case, we modify k1 in the branch delay slot, but we never need k0 again, so the new load is not needed, but since k1 is modified, if we do the load, we load from a garbage location and then get a nested TLB Refill, which is seen in userspace as either SIGBUS or SIGSEGV (depending on the garbage). The real fix is to only do this reloading if it is needed, and never where it is harmful.

2014-10-22ALSA: pcm: Disable mmap for known broken archsTakashi Iwai
Some architectures like PARISC is known not to support mmap properly with the DMA buffer, where dma_mmap_coherent() returns -EINVAL unconditionally. From the API POV, we should rather drop the mmap support there and expose it before the user-space tries to call mmap. The patch contains again ugly ifdef's, unfortunately, as there is no global flag indicating this. Once when such macro is defined, we can get rid of this instead.

2014-10-21OOM, PM: OOM killed task shouldn't escape PM suspendMichal Hocko
PM freezer relies on having all tasks frozen by the time devices are getting frozen so that no task will touch them while they are getting frozen. But OOM killer is allowed to kill an already frozen task in order to handle OOM situtation. In order to protect from late wake ups OOM killer is disabled after all tasks are frozen. This, however, still keeps a window open when a killed task didn't manage to die by the time freeze_processes finishes. Reduce the race window by checking all tasks after OOM killer has been disabled. This is still not race free completely unfortunately because oom_killer_disable cannot stop an already ongoing OOM killer so a task might still wake up from the fridge and get killed without freeze_processes noticing. Full synchronization of OOM and freezer is, however, too heavy weight for this highly unlikely case. Introduce and check oom_kills counter which gets incremented early when the allocator enters __alloc_pages_may_oom path and only check all the tasks if the counter changes during the freezing attempt. The counter is updated so early to reduce the race window since allocator checked oom_killer_disabled which is set by PM-freezing code. A false positive will push the PM-freezer into a slow path but that is not a big deal. Changes since v1 - push the re-check loop out of freeze_processes into check_frozen_processes and invert the condition to make the code more readable as per Rafael Fixes: f660daac474c6f (oom: thaw threads if oom killed thread is frozen before deferring) Cc: 3.2+ <stable@vger.kernel.org> # 3.2+ Signed-off-by: Michal Hocko <mhocko@suse.cz> Signed-off-by: Rafael J.

2014-10-21freezer: Do not freeze tasks killed by OOM killerCong Wang
Since f660daac474c6f (oom: thaw threads if oom killed thread is frozen before deferring) OOM killer relies on being able to thaw a frozen task to handle OOM situation but a3201227f803 (freezer: make freezing() test freeze conditions in effect instead of TIF_FREEZE) has reorganized the code and stopped clearing freeze flag in __thaw_task. This means that the target task only wakes up and goes into the fridge again because the freezing condition hasn't changed for it. This reintroduces the bug fixed by f660daac474c6f. Fix the issue by checking for TIF_MEMDIE thread flag in freezing_slow_path and exclude the task from freezing completely. If a task was already frozen it would get woken by __thaw_task from OOM killer and get out of freezer after rechecking freezing(). Changes since v1 - put TIF_MEMDIE check into freezing_slowpath rather than in __refrigerator as per Oleg - return __thaw_task into oom_scan_process_thread because oom_kill_process will not wake task in the fridge because it is sleeping uninterruptible [mhocko@suse.cz: rewrote the changelog] Fixes: a3201227f803 (freezer: make freezing() test freeze conditions in effect instead of TIF_FREEZE) Cc: 3.3+ <stable@vger.kernel.org> # 3.3+ Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: Michal Hocko <mhocko@suse.cz> Acked-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Rafael J.

2014-10-21arm: socfpga: fix fetching cpu1start_addr for SMPDinh Nguyen
When CPU1 is brought out of reset, it's MMU is not turned on yet, so it will only be able to use physical addresses. For systems with that have the MMU page configured for 0xC0000000, 0x80000000, or 0x40000000 "BIC 0x40000000" will work just fine, as it was just converting the virtual address of &cpu1start_addr into a physical address, ie. 0xC0000000 became 0x80000000. So for systems where the SDRAM controller was able to do a wrap-around access, this was working fine, as it was just dropping the MSB, but for systems where out of bounds memory access is not allowed, this would not allow CPU1 to correctly fetch &cpu1start_addr. This patch fixes the secondary_trampoline code to correctly fetch the physical address of cpu1start_addr directly. The patch will subtract the correct PAGE_OFFSET from &cpu1start_addr. And since on this platform, the physical memory will always start at 0x0, subtracting PAGE_OFFSET from &cpu1start_addr will allow CPU1 to correctly fetch the value of cpu1start_addr. While at it, change the name of cpu1start_addr to socfpga_cpu1start_addr to avoid any future naming collisions for multiplatform image. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com> --- v4: Updated commit log to correctly lay out the usage of PAGE_OFFSET and add comments to the same effect. v3: Used PAGE_OFFSET to get the physical address v2: Correctly get the physical address instead of just a BIC hack.

2014-10-21ALSA: pcm: Fix false lockdep warningsTakashi Iwai
As PCM core handles the multiple linked streams in parallel, lockdep gets confused (partly because of weak annotations) and spews the false-positive warnings. This hasn't been a problem for long time but the latest PCM lock path update seems to have woken up a sleeping dog. Here is an attempt to paper over this issue: pass the lock subclass just calculated from the depth in snd_pcm_action_group(). Also, a (possibly) wrong lock subclass set in snd_pcm_action_lock_mutex() is dropped, too.

2014-10-21ALSA: ctxfi: remove unused variableSudip Mukherjee
As of now the pointer to struct dai is not being used anywhere in the function. So it is safe to remove the variable. If we are ever doing anything with the container_of(daio, struct dai, daio), then at that time we can again add the variable.
