These two patches are supposed to "fix" failed order-4 memory allocations which have been observed when reading /proc/stat. The problem has been observed on s390 as well as on x86. To address the problem change the seq_file memory allocations to fallback to use vmalloc, so that allocations also work if memory is fragmented. This approach seems to be simpler and less intrusive than changing /proc/stat to use an interator. Also it "fixes" other users as well, which use seq_file's single_open() interface. This patch (of 2): Use seq_file's single_open_size() to preallocate a buffer that is large enough to hold the whole output, instead of open coding it. Also calculate the requested size using the number of online cpus instead of possible cpus, since the size of the output only depends on the number of online cpus. Signed-off-by:

Until now, the kernel has the same policy to handle victimized page frames that belong to kernel-space(reserved/slab-subsystem) or non-LRU(unknown page state). In other word, the result of handling either of these victimized page frames is (IGNORED | FAILED), and the return value of memory_failure() is -EBUSY. This patch is to avoid that memory_failure() returns very soon due to the "true" value of (!PageLRU(p)), and it also ensures that action_result() can report more precise information("reserved kernel", "kernel slab", and "unknown page state") instead of "non LRU", especially for memory errors which are detected by memory-scrubbing. Andi said: : While running the mcelog test suite on 3.14 I hit the following VM_BUG_ON: : : soft_offline: 0x56d4: unknown non LRU page type 3ffff800008000 : page:ffffea000015b400 count:3 mapcount:2097169 mapping: (null) index:0xffff8800056d7000 : page flags: 0x3ffff800004081(locked|slab|head) : ------------[ cut here ]------------ : kernel BUG at mm/rmap.c:1495! : : I think what happened is that a LRU page turned into a slab page in : parallel with offlining. memory_failure initially tests for this case, : but doesn't retest later after the page has been locked. : : ... : : I ran this patch in a loop over night with some stress plus : the mcelog test suite running in a loop.

Alexander reported mkswap on /dev/zram0 is failed if other process is opening the block device file. Step is as follows, 0. Reset the unused zram device. 1. Use a program that opens /dev/zram0 with O_RDWR and sleeps until killed. 2. While that program sleeps, echo the correct value to /sys/block/zram0/disksize. 3. Verify (e.g. in /proc/partitions) that the disk size is applied correctly. It is. 4. While that program still sleeps, attempt to mkswap /dev/zram0. This fails: mkswap: error: swap area needs to be at least 40 KiB When I investigated, the size get by ioctl(fd, BLKGETSIZE64, xxx) on mkswap to get a size of blockdev was zero although zram0 has right size by 2. The reason is zram didn't revalidate disk after changing capacity so that size of blockdev's inode is not uptodate until all of file is close. This patch should fix the BUG. Signed-off-by:

min_partial means minimum number of slab cached in node partial list. So, if nr_partial is less than it, we keep newly empty slab on node partial list rather than freeing it. But if nr_partial is equal or greater than it, it means that we have enough partial slabs so should free newly empty slab. Current implementation missed the equal case so if we set min_partial is 0, then, at least one slab could be cached. This is critical problem to kmemcg destroying logic because it doesn't works properly if some slabs is cached. This patch fixes this problem. Fixes 91cb69620284 ("slub: make dead memcg caches discard free slabs immediately"). Signed-off-by:Joonsoo Kim <iamjoonsoo.kim@lge.com> Acked-by:

This in turn causes accesses past zone->free_list[]. Fix the problem by changing init_cma_reserved_pageblock() such that it splits pageblock into individual MAX_ORDER pages if pageblock is bigger than a MAX_ORDER page. In cases where !CONFIG_HUGETLB_PAGE_SIZE_VARIABLE, which is all architectures expect for ia64, powerpc and tile at the moment, the âpageblock_order > MAX_ORDERâ condition will be optimised out since both sides of the operator are constants. In cases where pageblock size is variable, the performance degradation should not be significant anyway since init_cma_reserved_pageblock() is called only at boot time at most MAX_CMA_AREAS times which by default is eight.

On the syscall tracing path, we call out to secure_computing() to allow seccomp to check the syscall number being attempted. As part of this, a SIGTRAP may be sent to the tracer and the syscall could be re-written by a subsequent SET_SYSCALL ptrace request. Unfortunately, this new syscall is ignored by the current code unless TIF_SYSCALL_TRACE is also set on the current thread. This patch slightly reworks the enter path of the syscall tracing code so that we always reload the syscall number from current_thread_info()->syscall after the potential ptrace traps. Acked-by:

Commit 1c2f87c2 (ARM: 8025/1: Get rid of meminfo) changed find_limits to use memblock_get_current_limit for calculating the max_low pfn. nommu targets never actually set a limit on memblock though which means memblock_get_current_limit will just return the default value.

When a PL310 cache is used on a system that provides hardware coherency, the outer cache sync operation is useless, and can be skipped. Moreover, on some systems, it is harmful as it causes deadlocks between the Marvell coherency mechanism, the Marvell PCIe controller and the Cortex-A9. To avoid this, this commit introduces a new Device Tree property 'arm,io-coherent' for the L2 cache controller node, valid only for the PL310 cache. It identifies the usage of the PL310 cache in an I/O coherent configuration. Internally, it makes the driver disable the outer cache sync operation. Note that technically speaking, a fully coherent system wouldn't require any of the other .outer_cache operations. However, in practice, when booting secondary CPUs, these are not yet coherent, and therefore a set of cache maintenance operations are necessary at this point. This explains why we keep the other .outer_cache operations and only ->sync is disabled. While in theory any write to a PL310 register could cause the deadlock, in practice, disabling ->sync is sufficient to workaround the deadlock, since the other cache maintenance operations are only used in very specific situations. Contrary to previous versions of this patch, this new version does not simply NULL-ify the ->sync member, because the l2c_init_data structures are now 'const' and therefore cannot be modified, which is a good thing. Therefore, this patch introduces a separate l2c_init_data instance, called of_l2c310_coherent_data. Signed-off-by:

On uniprocessor preemptible kernel, target core deadlocks on unload. The following events happen: * iscsit_del_np is called * it calls send_sig(SIGINT, np->np_thread, 1); * the scheduler switches to the np_thread * the np_thread is woken up, it sees that kthread_should_stop() returns false, so it doesn't terminate * the np_thread clears signals with flush_signals(current); and goes back to sleep in iscsit_accept_np * the scheduler switches back to iscsit_del_np * iscsit_del_np calls kthread_stop(np->np_thread); * the np_thread is waiting in iscsit_accept_np and it doesn't respond to kthread_stop The deadlock could be resolved if the administrator sends SIGINT signal to the np_thread with killall -INT iscsi_np The reproducible deadlock was introduced in commit db6077fd, but the thread-stopping code was racy even before. This patch fixes the problem. Using kthread_should_stop to stop the np_thread is unreliable, so we test np_thread_state instead. If np_thread_state equals ISCSI_NP_THREAD_SHUTDOWN, the thread exits.

We had assumed that the physical address zero was invalid and would fail it. But that is not true and on some architectures it is not reserved and valid.

Pull sound fixes from Takashi Iwai: "Here includes a few patchset for fixing mostly HD-audio issues in addition to a patch assuring the compress API bytes alignment and a fix for the die-hard existing race condition at USB-audio disconnection.
