      inotify: clean up inotify_read and fix locking problems · 3632dee2
      Vegard Nossum authored
      If userspace supplies an invalid pointer to a read() of an inotify
      instance, the inotify device's event list mutex is unlocked twice.
      This causes an unbalance which effectively leaves the data structure
      unprotected, and we can trigger oopses by accessing the inotify
      instance from different tasks concurrently.
      
      The best fix (contributed largely by Linus) is a total rewrite
      of the function in question:

      fuse: fix poll notify · f6d47a17
      Miklos Szeredi authored
      Move fuse_copy_finish() to before calling fuse_notify_poll_wakeup().
      This is not a big issue because fuse_notify_poll_wakeup() should be
      atomic, but it's cleaner this way, and later uses of notification will
      need to be able to finish the copying before performing some actions.

      fuse: destroy bdi on umount · 26c36791
      Miklos Szeredi authored
      If a fuse filesystem is unmounted but the device file descriptor
      remains open and a new mount reuses the old device number, then the
      mount fails with EEXIST and the following warning is printed in the
      kernel log:
      
        WARNING: at fs/sysfs/dir.c:462 sysfs_add_one+0x35/0x3d()
        sysfs: duplicate filename '0:15' can not be created
      
      The cause is that the bdi belonging to the fuse filesystem was
      destoryed only after the device file was released.  Fix this by
      calling bdi_destroy() from fuse_put_super() instead.

      Impact: fix boot hang on pre-model-15 Intel CPUs
      
      rdmsrl_safe() does not work in very early bootup code yet, because we
      dont have the pagefault handler installed yet so exception section
      does not get parsed. rdmsr_safe() will just crash and hang the bootup.
      
      So limit the MSR_IA32_MISC_ENABLE MSR read to those CPU types that

      x86: work around PAGE_KERNEL_WC not getting WC in iomap_atomic_prot_pfn. · ef5fa0ab
      Eric Anholt authored
      In the absence of PAT, PAGE_KERNEL_WC ends up mapping to a memory type that
      gets UC behavior even in the presence of a WC MTRR covering the area in
      question.  By swapping to PAGE_KERNEL_UC_MINUS, we can get the actual
      behavior the caller wanted (WC if you can manage it, UC otherwise).
      
      This recovers the 40% performance improvement of using WC in the DRM
      to upload vertex data.

      x86: use standard PIT frequency · e1b4d114
      Ingo Molnar authored
      the RDC and ELAN platforms use slighly different PIT clocks, resulting in
      a timex.h hack that changes PIT_TICK_RATE during build time. But if a
      tester enables any of these platform support .config options, the PIT
      will be miscalibrated on standard PC platforms.
      
      So use one frequency - in a subsequent patch we'll add a quirk to allow
      x86 platforms to define different PIT frequencies.
