Introduce perf_cache object and interfaces to create, add entries, commit, and delete the object. perf_cache represents a file for the cached "perf probe" definitions on one binary file or vmlinux which has its own build id.

Fix rm_rf() to handle non-regular files correctly. This fix includes two changes; - Fix to use lstat(3) instead of stat(3) since if the target file is a symbolic link, rm_rf() should unlink the symbolic link itself, not the file which pointed by the symlink. - Fix to unlink non-regular files (except for directory), including symlink. Even though the first one fixes to stat symlink itself, without second fix, it still failed because the symlink is not a regular file.

Andi Kleen authored
The NMI watchdog uses either the fixed cycles or a generic cycles counter. This causes a lot of conflicts with users of the PMU who want to run a full group including the cycles fixed counter, for example the --topdown support recently added to perf stat. The code needs to fall back to not use groups, which can cause measurement inaccuracy due to multiplexing errors. This patch switches the NMI watchdog to use reference cycles on Intel systems. This is actually more accurate than cycles, because cycles can tick faster than the measured CPU Frequency due to Turbo mode. The ref cycles always tick at their frequency, or slower when the system is idling. That means the NMI watchdog can never expire too early, unlike with cycles. The reference cycles tick roughly at the frequency of the TSC, so the same period computation can be used.

This time I am very grateful that Ricardo Ribalda Delgado went in and fixed my stupid refcounting mistakes in the removal path for GPIO chips. I had a feeling something was wrong here and so it was.

Summary: - Fix a NULL pointer dereference when we are searching the GPIO device list but one of the devices have been removed (struct gpio_chip pointer is NULL). - Fix unaligned reference counters: we were ending on +3 after all said and done. It should be 0. Remove an extraneous get_device(), and call cdev_del() followed by device_del() in gpiochip_remove() instead and the count goes to zero and calls the release() function properly. - Fix a compile warning due to a missing #include in the OF/device tree portions. - Select ANON_INODES for GPIOLIB, we're using that for our character device.

The first patch removes the indirection. The second one cleans up the code. Compile-tested only. I have the hardware, but I have absolutely no idea what XU does, how to use it, what software to recompile as 32-bit, or what to test in that software" * tag '20160610_uvc_compat_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/luto/linux: uvc_v4l2: Simplify compat ioctl implementation uvc: Forward compat ioctls to their handlers directly

The uvc compat ioctl implementation seems to have copied user data for no good reason. Remove a bunch of copies. Signed-off-by: Andy Lutomirski <luto@kernel.org>

The current code goes through a lot of indirection just to call a known handler. Simplify it: just call the handlers directly. Cc: stable@vger.kernel.org Signed-off-by: Andy Lutomirski <luto@kernel.org>

Pull btrfs fixes from Chris Mason: "Has some fixes and some new self tests for btrfs. The self tests are usually disabled in the .config file (unless you're doing btrfs dev work), and this bunch is meant to find problems with the 64K page size patches. Jeff has a patch to help people see if they are using the hardware assist crc32c module, which really helps us nail down problems when people ask why crcs are using so much CPU. Otherwise, it's small fixes" * 'for-linus-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: Btrfs: self-tests: Fix extent buffer bitmap test fail on BE system Btrfs: self-tests: Fix test_bitmaps fail on 64k sectorsize Btrfs: self-tests: Use macros instead of constants and add missing newline Btrfs: self-tests: Support testing all possible sectorsizes and nodesizes Btrfs: self-tests: Execute page straddling test only when nodesize < PAGE_SIZE btrfs: advertise which crc32c implementation is being used at module load Btrfs: add validadtion checks for chunk loading Btrfs: add more validation checks for superblock Btrfs: clear uptodate flags of pages in sys_array eb Btrfs: self-tests: Support non-4k page size Btrfs: Fix integer overflow when calculating bytes_per_bitmap Btrfs: test_check_exists: Fix infinite loop when searching for free space entries Btrfs: end transaction if we abort when creating uuid root btrfs: Use __u64 in exported linux/btrfs.h.
