This driver's IRQ registration is failing because the kernel now forces IRQs to be ONESHOT if no IRQ handler is passed.

If page migration cannot charge the temporary page to the memcg, migrate_pages() will return -ENOMEM. This isn't considered in memory compaction however, and the loop continues to iterate over all pageblocks trying to isolate and migrate pages. If a small number of very large memcgs happen to be oom, however, these attempts will mostly be futile leading to an enormous amout of cpu consumption due to the page migration failures. This patch will short circuit and fail memory compaction if migrate_pages() returns -ENOMEM. COMPACT_PARTIAL is returned in case some migrations were successful so that the page allocator will retry.

"no other files mapped" requirement from my previous patch (c/r: prctl: update prctl_set_mm_exe_file() after mm->num_exe_file_vmas removal) is too paranoid, it forbids operation even if there mapped one shared-anon vma. Let's check that current mm->exe_file already unmapped, in this case exe_file symlink already outdated and its changing is reasonable. Plus, this patch fixes exit code in case operation success.

kswapd_stop() is called to destroy the kswapd work thread when all memory of a NUMA node has been offlined. But kswapd_stop() only terminates the work thread without resetting NODE_DATA(nid)->kswapd to NULL. The stale pointer will prevent kswapd_run() from creating a new work thread when adding memory to the memory-less NUMA node again. Eventually the stale pointer may cause invalid memory access. An example stack dump as below. It's reproduced with 2.6.32, but latest kernel has the same issue.

We already use them for openat() and friends, but fchdir() also wants to be able to use O_PATH file descriptors. This should make it comparable to the O_SEARCH of Solaris. In particular, O_PATH allows you to access (not-quite-open) a directory you don't have read persmission to, only execute permission. Noticed during development of multithread support for ksh93.

File operations on /dev/ecryptfs would BUG() when the operations were performed by processes other than the process that originally opened the file. This could happen with open files inherited after fork() or file descriptors passed through IPC mechanisms. Rather than calling BUG(), an error code can be safely returned in most situations. In ecryptfs_miscdev_release(), eCryptfs still needs to handle the release even if the last file reference is being held by a process that didn't originally open the file. ecryptfs_find_daemon_by_euid() will not be successful, so a pointer to the daemon is stored in the file's private_data. The private_data pointer is initialized when the miscdev file is opened and only used when the file is released. https://launchpad.net/bugs/994247Signed-off-by: NTyler Hicks <tyhicks@canonical.com> Reported-by: NSasha Levin <levinsasha928@gmail.com> Tested-by: NSasha Levin <levinsasha928@gmail.com>

Pull btrfs updates from Chris Mason: "I held off on my rc5 pull because I hit an oops during log recovery after a crash. I wanted to make sure it wasn't a regression because we have some logging fixes in here. It turns out that a commit during the merge window just made it much more likely to trigger directory logging instead of full commits, which exposed an old bug. The new backref walking code got some additional fixes. This should be the final set of them. Josef fixed up a corner where our O_DIRECT writes and buffered reads could expose old file contents (not stale, just not the most recent). He and Liu Bo fixed crashes during tree log recover as well.

Pull DT fixes from Rob Herring: "Mainly some documentation updates and 2 fixes: - An export symbol fix for of_platform_populate from Stephen W. - A fix for the order compatible entries are matched to ensure the first compatible string is matched when there are multiple matches." Normally these would go through Grant Likely (thus the "fixes-for-grant" branch name), but Grant is in the middle of moving to Scotland, and is practically offline until sometime in August. So pull directly from Rob. * 'fixes-for-grant' of git://sources.calxeda.com/kernel/linux: of: match by compatible property first dt: mc13xxx.txt: Fix gpio number assignment dt: fsl-fec.txt: Fix gpio number assignment dt: fsl-mma8450.txt: Add missing 'reg' description dt: fsl-imx-esdhc.txt: Fix gpio number assignment dt: fsl-imx-cspi.txt: Fix comment about GPIOs used for chip selects of: Add Avionic Design vendor prefix of: export of_platform_populate()

'sub pc, pc, #1b-2b+8-2' results in address<1:0> == '10'. sub pc, pc, #const (== ADR pc, #const) performs an interworking branch (BXWritePC()) on ARMv7+ and a simple branch (BranchWritePC()) on earlier versions. In ARM state, BXWritePC() is UNPREDICTABLE when address<1:0> == '10'. In ARM state on ARMv6+, BranchWritePC() ignores address<1:0>. Before ARMv6, BranchWritePC() is UNPREDICTABLE if address<1:0> != '00' So the instruction is UNPREDICTABLE both before and after v6.

We currently return -EPERM if the user requests mode exclusion that is not supported by the CPU. This looks pretty confusing from userspace and is inconsistent with other architectures (ppc, x86). This patch returns -EOPNOTSUPP instead. Signed-off-by: NWill Deacon <will.deacon@arm.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This reverts commit 6b5c8045. Conflicts: arch/arm/kernel/ptrace.c The new syscall restarting code can lead to problems if we take an interrupt in userspace just before restarting the svc instruction. If a signal is delivered when returning from the interrupt, the TIF_SYSCALL_RESTARTSYS will remain set and cause any syscalls executed from the signal handler to be treated as a restart of the previously interrupted system call. This includes the final sigreturn call, meaning that we may fail to exit from the signal context. Furthermore, if a system call made from the signal handler requires a restart via the restart_block, it is possible to clear the thread flag and fail to restart the originally interrupted system call. The right solution to this problem is to perform the restarting in the kernel, avoiding the possibility of handling a further signal before the restart is complete. Since we're almost at -rc6, let's revert the new method for now and aim for in-kernel restarting at a later date.
