On exynos5250, exynos5420 and exynos5260 it was observed that, after 1 cycle of S2R, the rtc-tick occurs at a very fast rate as compared to the rtc-tick occuring before S2R. This patch fixes the above issue by correcting the wrong way of save/restore of S3C2410_TICNT for TYPE_S3C64XX.

Currently symbols that are absolute addresses are incorrectly displayed in /proc/kallsyms if the kernel is loaded with kASLR. The problem was that the scripts/kallsyms.c file which generates the array of symbol names and addresses uses an relocatable value for all symbols, even absolute symbols. This patch fixes that. Several kallsyms output in different boot states for comparison: $ egrep '_(stext|_per_cpu_(start|end))' /root/kallsyms.nokaslr 0000000000000000 D __per_cpu_start 0000000000014280 D __per_cpu_end ffffffff810001c8 T _stext $ egrep '_(stext|_per_cpu_(start|end))' /root/kallsyms.kaslr1 000000001f200000 D __per_cpu_start 000000001f214280 D __per_cpu_end ffffffffa02001c8 T _stext $ egrep '_(stext|_per_cpu_(start|end))' /root/kallsyms.kaslr2 000000000d400000 D __per_cpu_start 000000000d414280 D __per_cpu_end ffffffff8e4001c8 T _stext $ egrep '_(stext|_per_cpu_(start|end))' /root/kallsyms.kaslr-fixed 0000000000000000 D __per_cpu_start 0000000000014280 D __per_cpu_end ffffffffadc001c8 T _stext Signed-off-by: NAndy Honig <ahonig@google.com> Signed-off-by: NKees Cook <keescook@chromium.org> Cc: Michal Marek <mmarek@suse.cz> Cc: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

LZ4 as implemented in the kernel differs from the default method now used by the reference implementation of LZ4. Until the in-kernel method is updated to support the new default, passing the legacy flag (-l) to the compressor is necessary. Without this flag the kernel-generated, LZ4-compressed initramfs is junk. Kyungsik said: : It seems that lz4 supports legacy format with the same option as lz4c : does. Just looking at the first few bytes of lz4 compressed image, we can : see whether it is new format or not. : : It shows new format magic number without this patch.

This can be reproduced with default config since 3.11 kernels. A reproducer can be found in the kernel's selftest directory for networking by running ./psock_tpacket. The problem is that an order=2 compound page (allocated by alloc_one_pg_vec_page() is part of the munlocked VM_MIXEDMAP vma (mapped by packet_mmap()) and mistaken for a THP page and assumed to be order=9. The checks for THP in munlock came with commit ff6a6da6 ("mm: accelerate munlock() treatment of THP pages"), i.e. since 3.9, but did not trigger a bug. It just makes munlock_vma_pages_range() skip such compound pages until the next 512-pages-aligned page, when it encounters a head page. This is however not a problem for vma's where mlocking has no effect anyway, but it can distort the accounting. Since commit 7225522b ("mm: munlock: batch non-THP page isolation and munlock+putback using pagevec") this can trigger a VM_BUG_ON in PageTransHuge() check. This patch fixes the issue by adding VM_MIXEDMAP flag to VM_SPECIAL, a list of flags that make vma's non-mlockable and non-mergeable. The reasoning is that VM_MIXEDMAP vma's are similar to VM_PFNMAP, which is already on the VM_SPECIAL list, and both are intended for non-LRU pages where mlocking makes no sense anyway.

Sometimes the cleanup after memcg hierarchy testing gets stuck in mem_cgroup_reparent_charges(), unable to bring non-kmem usage down to 0. There may turn out to be several causes, but a major cause is this: the workitem to offline parent can get run before workitem to offline child; parent's mem_cgroup_reparent_charges() circles around waiting for the child's pages to be reparented to its lrus, but it's holding cgroup_mutex which prevents the child from reaching its mem_cgroup_reparent_charges(). Further testing showed that an ordered workqueue for cgroup_destroy_wq is not always good enough: percpu_ref_kill_and_confirm's call_rcu_sched stage on the way can mess up the order before reaching the workqueue. Instead, when offlining a memcg, call mem_cgroup_reparent_charges() on all its children (and grandchildren, in the correct order) to have their charges reparented first.

Commit 0eef6156 ("memcg: fix css reference leak and endless loop in mem_cgroup_iter") got the interaction with the commit a few before it d8ad3055 ("mm/memcg: iteration skip memcgs not yet fully initialized") slightly wrong, and we didn't notice at the time. It's elusive, and harder to get than the original, but for a couple of days before rc1, I several times saw a endless loop similar to that supposedly being fixed. This time it was a tighter loop in __mem_cgroup_iter_next(): because we can get here when our root has already been offlined, and the ordering of conditions was such that we then just cycled around forever.

While debug_dma_assert_idle() checks if a given *page* is actively undergoing dma the valid granularity of a dma mapping is a *cacheline*. Sander's testing shows that the warning message "DMA-API: exceeded 7 overlapping mappings of pfn..." is falsely triggering. The test is simply mapping multiple cachelines in a given page. Ultimately we want overlap tracking to be valid as it is a real api violation, so we need to track active mappings by cachelines. Update the active dma tracking to use the page-frame-relative cacheline of the mapping as the key, and update debug_dma_assert_idle() to check for all possible mapped cachelines for a given page. However, the need to track active mappings is only relevant when the dma-mapping is writable by the device. In fact it is fairly standard for read-only mappings to have hundreds or thousands of overlapping mappings at once. Limiting the overlap tracking to writable (!DMA_TO_DEVICE) eliminates this class of false-positive overlap reports. Note, the radix gang lookup is sub-optimal. It would be best if it stopped fetching entries once the search passed a page boundary. Nevertheless, this implementation does not perturb the original net_dma failing case. That is to say the extra overhead does not show up in terms of making the failing case pass due to a timing change.

Commit bf6bddf1 ("mm: introduce compaction and migration for ballooned pages") introduces page_count(page) into memory compaction which dereferences page->first_page if PageTail(page). This results in a very rare NULL pointer dereference on the aforementioned page_count(page). Indeed, anything that does compound_head(), including page_count() is susceptible to racing with prep_compound_page() and seeing a NULL or dangling page->first_page pointer. This patch uses Andrea's implementation of compound_trans_head() that deals with such a race and makes it the default compound_head() implementation. This includes a read memory barrier that ensures that if PageTail(head) is true that we return a head page that is neither NULL nor dangling. The patch then adds a store memory barrier to prep_compound_page() to ensure page->first_page is set. This is the safest way to ensure we see the head page that we are expecting, PageTail(page) is already in the unlikely() path and the memory barriers are unfortunately required. Hugetlbfs is the exception, we don't enforce a store memory barrier during init since no race is possible.

Although diffstat shows much, the changes are simple: there are just so many different device entries there" * tag 'sound-3.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ASoC: sta32x: Fix wrong enum for limiter2 release rate ASoC: da732x: Mark DC offset control registers volatile ALSA: hda/realtek - Add more entry for enable HP mute led ALSA: hda - Add a fixup for HP Folio 13 mute LED ASoC: wm8958-dsp: Fix firmware block loading ASoC: sta32x: Fix cache sync ALSA: hda/realtek - Add more entry for enable HP mute led ASoC: dapm: Add locking to snd_soc_dapm_xxxx_pin functions Input - arizona-haptics: Fix double lock of dapm_mutex ASoC: wm8400: Fix the wrong number of enum items ASoC: isabelle: Fix the wrong number of items in enum ctls ASoC: ad1980: Fix wrong number of items for capture source ASoC: wm8994: Fix the wrong number of enum items ASoC: wm8900: Fix the wrong number of enum items ASoC: wm8770: Fix wrong number of enum items ASoC: sta32x: Fix array access overflow ASoC: dapm: Correct regulator bypass error messages

Page table entries on ARM64 are 64 bits, and some pte functions such as pte_dirty return a bitwise-and of a flag with the pte value. If the flag to be tested resides in the upper 32 bits of the pte, then we run into the danger of the result being dropped if downcast. For example: gather_stats(page, md, pte_dirty(*pte), 1); where pte_dirty(*pte) is downcast to an int. This patch adds a double logical invert to all the pte_ accessors to ensure predictable downcasting.

When remapping a block to the cache's fast device that is larger than 2TB we must not truncate the destination sector to 32bits. The 32bit temporary result of from_cblock() was being overflowed in remap_to_cache() due to the logical left shift. Use an intermediate 64bit type to store the 32bit from_cblock() result to fix the overflow.

When compiling perf tool code with gcc 4.4.7 I'm getting following error: CC util/session.o cc1: warnings being treated as errors util/session.c: In function ‘perf_session_deliver_event’: tools/perf/util/include/linux/bitops.h:109: error: dereferencing pointer ‘p’ does break strict-aliasing rules tools/perf/util/include/linux/bitops.h:101: error: dereferencing pointer ‘p’ does break strict-aliasing rules util/session.c:697: note: initialized from here tools/perf/util/include/linux/bitops.h:101: note: initialized from here make[1]: *** [util/session.o] Error 1 make: *** [util/session.o] Error 2 The aliased types here are u64 and unsigned long pointers, which is safe for the find_first_bit processing. This error shows up for me only for gcc 4.4 on 32bit x86, even for -Wstrict-aliasing=3, while newer gcc are quiet and scream here for -Wstrict-aliasing={2,1}. Looks like newer gcc changed the rules for strict alias warnings. The gcc documentation offers workaround for valid aliasing by using __may_alias__ attribute: http://gcc.gnu.org/onlinedocs/gcc-4.4.0/gcc/Type-Attributes.html Using this workaround for the find_first_bit function.
