      [PATCH] Fix x86-64 boot problem · 839401aa
      Andrew Morton authored
      From: Andi Kleen <ak@muc.de>
      
      Fix a bug introduced with the last merge that prevented booting with
      CONFIG_DEBUG_INFO on on x86-64.  It would corrupt registers in interrupts.
      This has hit a few people, so I would consider it as a critical fix.

      [PATCH] CDROMREADAUDIO frames · 530c7720
      Andrew Morton authored
      From: Jens Axboe <axboe@suse.de>
      
      2.6 imposes a 64 frame limit where 2.4 does not (just relies on kmalloc()
      failing and limiting frames from that).  That breaks at least on guys app.
      With MSF adressing, it's much simpler to be able to ask for a full second
      at the time, so I think we should just allow that.  So bump the limit from
      64 to CD_FRAMES (which is 75).

      [PATCH] PCI Scan all functions · 04ab7a5e
      Andrew Morton authored
      From: Jake Moilanen <moilanen@austin.ibm.com>
      
      On a ppc64 logically partitioned system, there can be a setup where function
      0 of a PCI-PCI bridge is assigned to one partition and (for example) function
      2 is assigned to a second partition.  On the second partition, it would
      appear that function 0 does not exist, but function 2 does.  If all the
      functions are not scanned, everything under function 2 would not be detected.
      
      This patch allows devices that don't respond to function 0, but do respond to
      other functions to be marked with a quirk and have all of their functions
      scanned.

      [PATCH] Move cpu_vm_mask to be closer to mmu_context_t in struct mm · 48ceccc1
      Andrew Morton authored
      From: Jack Steiner <steiner@sgi.com>
      
      The cpu_vm_mask use to be close to the mmu_context_t field in the mm
      struct.  Recently some large members were added between "cpu_vm_mask" and
      "context".  I suspect that was an oversight.
      
      Here is a patch that puts the fields close together.  This makes it likely
      that both fields are in the same cache line.  Since both fields are likely
      to be updated at the same time, this may improve performance.

      [PATCH] Lindent fixed to match reality · 9a76f566
      Andrew Morton authored
      From: Matt Mackall <mpm@selenic.com>
      
      I've been fiddling with cleaning up some old code here and suggest the
      following to make Lindent match actual practice more closely. This does:
      
      a) (no -psl)
      
      void *foo(void)
      {
      
       instead of
      
      void *
      foo(void) {
      
      b) (no -bs) "sizeof(foo)" rather than "sizeof (foo)"
      
      c) (-ncs) "(void *)foo" rather than "(void *) foo"

      [PATCH] shrink_list(): check PageSwapCache() after add_to_swap() · 5b1116c3
      Andrew Morton authored
      From: Nikita Danilov <Nikita@Namesys.COM>
      
      shrink_list() checks PageSwapCache() before calling add_to_swap(), this
      means that anonymous page that is going to be added to the swap right
      now these checks return false and:
      
       (*) it will be unaccounted for in nr_mapped, and
      
       (*) it won't be written to the swap if gfp_flags include __GFP_IO but
           not __GFP_FS.
      
      (Both will happen only on the next round of scanning.)
      
      Patch below just moves may_enter_fs initialization down. I am not sure
      about (*nr_mapped) increase though.

      [PATCH] Use address hint in mmap for search · ed205520
      Andrew Morton authored
      From: Andi Kleen <ak@suse.de>
      
      When the user gave an address hint in mmap use it as starting point for the
      search for !MAP_FIXED.
      
      Currently it is only checked directly and when already used the free area
      cache is used as starting point.  With this change you can use mmap(4096,
      ....) to e.g.  get the lowest free address in your address space, which is
      sometimes useful.  For example on x86-64 glibc wants to preferably allocate
      thread local data in the first 4GB but use higher addresses when this is
      not possible.
      
      This can be a bit more costly in CPU time because it may have to skip over
      more VMAs, but gives better semantics for most cases.  Most programs pass
      NULL as hint anyways so it won't make any difference for them.
      
      I did it for the generic mmap and for x86-64 for now.  Also minor white
      space fixes for x86-64.

      The patch fixes locking in proc_check_root().  It brings is_subdir() call
      under vfsmount_lock.  Holding vfsmount_lock will ensure mnt_mountpoint
      dentry is intact and the dentry does not go away while it is being checked
      in is_subdir().

      [PATCH] is_subdir locking fix · b5a660ee
      Andrew Morton authored
      From: Maneesh Soni <maneesh@in.ibm.com>
      
      o The following patch fixes is_subdir() races with d_move. Due to concurrent
        d_move, in is_subdir() we can end up accessing freed d_parent pointer in
        case of pre-emptible kernel. To avoid this we can use rcu_read_lock() and
        rcu_read_unlock().
      
      o This also fixes the seqlock uses in is_subdir() as we need to restart the
        the inner loop with the origianl new_dentry passed to the routine in case
        of any rename occured while we are traversing d_parent links.

      ac97_unregister_driver() is nulling out the ->driver field for all codecs.
      It should only null the codecs which are using this driver.

      [PATCH] u_int32_t causes cross-compile problems · c92a441a
      Andrew Morton authored
      From: Pratik Solanki <pratik.solanki@timesys.com>
      
      I came across this C standards issue while cross-compiling the Linux kernel
      with gcc on Solaris.  The file gen_crc32table.c uses the non-standard type
      u_int32_t.  It's possible that the host machine's sys/types.h does not
      define u_int32_t.  The attached patch replaces u_int32_t with the POSIX
      standard uint32_t and includes POSIX inttypes.h instead of sys/types.h.

      [PATCH] fix menuconfig choice item help display · ccd3fed5
      Andrew Morton authored
      From: Bjorn Helgaas <bjorn.helgaas@hp.com>
            Anders Gustafsson <andersg@0x63.nu>
            Roman Zippel <zippel@linux-m68k.org>
      
      This patch fixes menuconfig so it can display help text for individual
      choice group config entries.
      
      Previously it would only display the help text attached to the "choice"
      item.  There was no way to display the help attached to individual config
      entries inside the choice group.  Typically, the "choice" item has no help
      text, and all the useful help is attached to the individual entries, so
      this was a bit of a problem.

      btime in /proc/stat does not stay constant but decreases at a rate of 15
      secs/day, because we're assuming that HZ is exactly 100.  Use the correct
      adjustments to fix that up.

      [PATCH] Fine tune the time conversion to eliminate conversion errors. · 03718ae0
      Andrew Morton authored
      From: George Anzinger <george@mvista.com>
      
      The time conversion code is erroring on the side of a bit too small.  The
      attached patch forces any error to be on the high side.  The current code will
      convert 1 nanosecond to zero jiffies (standard says that should be 1).  It also
      is around 1 nanosecond late on each roll to the next jiffie.
      
      I have done some error checks with this patch applied and get the following
      errors in PPB ( Parts Per Billion):
      
      HZ     nano sec conversion     microsecond conversion
      1000    315                      45
      1024    227                      40
      100     28                       317
      
      In all cases the error is on the high side, which means that the final shift
      will, most likely, eliminate the error bits.

      Andrew Morton authored
      From: Mike Waychison <Michael.Waychison@Sun.COM>
      
      The attached patch ensures that we grab vfsmount_lock when grabbing a
      reference to mnt_parent in follow_up and follow_dotdot.
      
      We also don't need to access ->mnt_parent in follow_mount and
      __follow_down to mntput because we already the parent pointer on the stack.

      Unless I miss something this look like a typo, one user reported to get
      error from the daemon: 'Unknown event for counter 1' (alpha ev6) and the
      behavior was better but not completly sane after trying this patch: he get
      spurious event for counter 1 when enabling only counter 0 but rarely now.
      No alpha box to test this.
