Pull cgroup fixes from Tejun Heo: "This is quite late but these need to be backported anyway. This is the fix for a long-standing cpuset bug which existed from 2009. cpuset makes use of PF_SPREAD_{PAGE|SLAB} flags to modify the task's memory allocation behavior according to the settings of the cpuset it belongs to; unfortunately, when those flags have to be changed, cpuset did so directly even whlie the target task is running, which is obviously racy as task->flags may be modified by the task itself at any time. This obscure bug manifested as corrupt PF_USED_MATH flag leading to a weird crash. The bug is fixed by moving the flag to task->atomic_flags.

Pull ARM SoC fixes from Olof Johansson: "Here's our last set of fixes for 3.17.

Only exchange source and destination filenames if flags contain RENAME_EXCHANGE. In case if executable file was running and replaced by other file /proc/PID/exe should still show correct file name, not the old name of the file by which it was replaced. The scenario when this bug manifests itself was like this: * ALT Linux uses rpm and start-stop-daemon; * during a package upgrade rpm creates a temporary file for an executable to rename it upon successful unpacking; * start-stop-daemon is run subsequently and it obtains the (nonexistant) temporary filename via /proc/PID/exe thus failing to identify the running process. Note that "long" filenames (> DNAiME_INLINE_LEN) are still exchanged without RENAME_EXCHANGE and this behaviour exists long enough (should be fixed too apparently). So this patch is just an interim workaround that restores behavior for "short" names as it was before changes introduced by commit da1ce067 ("vfs: add cross-rename"). See https://lkml.org/lkml/2014/9/7/6 for details. AV: the comments about being more careful with ->d_name.hash than with ->d_name.name are from back in 2.3.40s; they became obsolete by 2.3.60s, when we started to unhash the target instead of swapping hash chain positions followed by d_delete() as we used to do when dcache was first introduced.

The third argument of fuse_get_user_pages() "nbytesp" refers to the number of bytes a caller asked to pack into fuse request. This value may be lesser than capacity of fuse request or iov_iter. So fuse_get_user_pages() must ensure that *nbytesp won't grow. Now, when helper iov_iter_get_pages() performs all hard work of extracting pages from iov_iter, it can be done by passing properly calculated "maxsize" to the helper. The other caller of iov_iter_get_pages() (dio_refill_pages()) doesn't need this capability, so pass LONG_MAX as the maxsize argument here. Fixes: c9c37e2e ("fuse: switch to iov_iter_get_pages()") Reported-by:

This fixes the same bug as b43790ee ("mm: softdirty: don't forget to save file map softdiry bit on unmap") and 9aed8614 ("mm/memory.c: don't forget to set softdirty on file mapped fault") where the return value of pte_*mksoft_dirty was being ignored. To be sure that no other pte/pmd "mk" function return values were being ignored, I annotated the functions in arch/x86/include/asm/pgtable.h with __must_check and rebuilt. The userspace effect of this bug is that the softdirty mark might be lost if a file mapped pte get zapped. Signed-off-by:

In PTE holes that contain VM_SOFTDIRTY VMAs, unmapped addresses before VM_SOFTDIRTY VMAs are reported as softdirty by /proc/pid/pagemap. This bug was introduced in commit 68b5a652 ("mm: softdirty: respect VM_SOFTDIRTY in PTE holes"). That commit made /proc/pid/pagemap look at VM_SOFTDIRTY in PTE holes but neglected to observe the start of VMAs returned by find_vma. Tested: Wrote a selftest that creates a PMD-sized VMA then unmaps the first page and asserts that the page is not softdirty. I'm going to send the pagemap selftest in a later commit. Signed-off-by:

This bug leads to reproducible silent data loss, despite the use of msync(), sync() and a clean unmount of the file system. It is easily reproducible with the following script: ----------------[BEGIN SCRIPT]-------------------- mkfs.nilfs2 -f /dev/sdb mount /dev/sdb /mnt dd if=/dev/zero bs=1M count=30 of=/mnt/testfile umount /mnt mount /dev/sdb /mnt CHECKSUM_BEFORE="$(md5sum /mnt/testfile)" /root/mmaptest/mmaptest /mnt/testfile 30 10 5 sync CHECKSUM_AFTER="$(md5sum /mnt/testfile)" umount /mnt mount /dev/sdb /mnt CHECKSUM_AFTER_REMOUNT="$(md5sum /mnt/testfile)" umount /mnt echo "BEFORE MMAP:\t$CHECKSUM_BEFORE" echo "AFTER MMAP:\t$CHECKSUM_AFTER" echo "AFTER REMOUNT:\t$CHECKSUM_AFTER_REMOUNT" ----------------[END SCRIPT]-------------------- The mmaptest tool looks something like this (very simplified, with error checking removed): ----------------[BEGIN mmaptest]-------------------- data = mmap(NULL, file_size - file_offset, PROT_READ | PROT_WRITE, MAP_SHARED, fd, file_offset); for (i = 0; i < write_count; ++i) { memcpy(data + i * 4096, buf, sizeof(buf)); msync(data, file_size - file_offset, MS_SYNC)) } ----------------[END mmaptest]-------------------- The output of the script looks something like this: BEFORE MMAP: 281ed1d5ae50e8419f9b978aab16de83 /mnt/testfile AFTER MMAP: 6604a1c31f10780331a6850371b3a313 /mnt/testfile AFTER REMOUNT: 281ed1d5ae50e8419f9b978aab16de83 /mnt/testfile So it is clear, that the changes done using mmap() do not survive a remount. This can be reproduced a 100% of the time. The problem was introduced in commit 136e8770 ("nilfs2: fix issue of nilfs_set_page_dirty() for page at EOF boundary"). If the page was read with mpage_readpage() or mpage_readpages() for example, then it has no buffers attached to it. In that case page_has_buffers(page) in nilfs_set_page_dirty() will be false. Therefore nilfs_set_file_dirty() is never called and the pages are never collected and never written to disk. This patch fixes the problem by also calling nilfs_set_file_dirty() if the page has no buffers attached to it. [akpm@linux-foundation.org: s/PAGE_SHIFT/PAGE_CACHE_SHIFT/] Signed-off-by:

Commit bbd426f5 "MIPS: Simplify FP context access" modified the SIFROMREG & SIFROMHREG macros such that they return unsigned rather than signed 32b integers. I had believed that to be fine, but inadvertently missed the MFC1 & MFHC1 cases which write to a struct pt_regs regs element. On MIPS32 this is fine, but on 64 bit those saved regs' fields are 64 bit wide. Using unsigned values caused the 32 bit value from the FP register to be zero rather than sign extended as the architecture specifies, causing incorrect emulation of the MFC1 & MFHc1 instructions. Fix by reintroducing the casts to signed integers, and therefore the sign extension. Signed-off-by:

Pull i2c fixes from Wolfram Sang: "This is probably not the kind of pull request you want to see that late in the cycle. Yet, the ACPI refactorization was problematic again and caused another two issues which need fixing. My holidays with limited internet (plus travelling) and the developer's illness didn't help either :( The details: - ACPI code was refactored out into a seperate file and as a side-effect, the i2c-core module got renamed. Jean Delvare rightfully complained about the rename being problematic for distributions. So, Mika and I thought the least problematic way to deal with it is to move all the code back into the main i2c core source file. This is mainly a huge code move with some #ifdeffery applied. No functional code changes. Our personal tests and the testbots did not find problems. (I was thinking about reverting, too, yet that would also have ~800 lines changed) - The new ACPI code also had a NULL pointer exception, thanks to Peter for finding and fixing it. - Mikko fixed a locking problem by decoupling clock_prepare and clock_enable. - Addy learnt that the datasheet was wrong and reimplemented the frequency setup according to the new algorithm. - Fan fixed an off-by-one error when copying data - Janusz fixed a copy'n'paste bug which gave a wrong error message - Sergei made sure that "don't touch" bits are not accessed" * 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: acpi: Fix NULL Pointer dereference i2c: move acpi code back into the core i2c: rk3x: fix divisor calculation for SCL frequency i2c: mxs: fix error message in pio transfer i2c: ismt: use correct length when copy buffer i2c: rcar: fix RCAR_IRQ_ACK_{RECV|SEND} i2c: tegra: Move clk_prepare/clk_set_rate to probe
