      Fix up the maintainers info in the tpm drivers.  Kylene will be out for
some time, so copying the sourceforge list is the best way to get some
attention.

      sparsemem: ensure we initialise the node mapping for SPARSEMEM_STATIC · 85770ffe
      Andy Whitcroft authored 
      Booting SPARSEMEM on NUMA systems trips a BUG in page_alloc.c:

	Initializing HighMem for node 0 (00038000:00100000)
	Initializing HighMem for node 1 (00100000:001ffe00)
	------------[ cut here ]------------
	kernel BUG at /home/apw/git/linux-2.6/mm/page_alloc.c:456!
	[...]

This occurs because the section to node id mapping is not being
setup correctly during init under SPARSEMEM_STATIC, leading to an
attempt to free pages from all nodes into the zones on node 0.

When the zone_table[] was removed in the following commit, a new
section to node mapping table was introduced:

    commit 89689ae7
    [PATCH] Get rid of zone_table[]

That conversion inadvertantly only initialised the node mapping in
SPARSEMEM_EXTREME.  Ensure we initialise the node mapping in
SPARSEMEM_STATIC.

[akpm@linux-foundation.org: make the stubs static inline]

      eCryptfs: fix lookup error for special files · df068464
      Ryusuke Konishi authored 
      When ecryptfs_lookup() is called against special files, eCryptfs generates
the following errors because it tries to treat them like regular eCryptfs
files.

Error opening lower file for lower_dentry [0xffff810233a6f150], lower_mnt [0xffff810235bb4c80], and flags [0x8000]
Error opening lower_file to read header region
Error attempting to read the [user.ecryptfs] xattr from the lower file; return value = [-95]
Valid metadata not found in header region or xattr region; treating file as unencrypted

For instance, the problem can be reproduced by the steps below.

  # mkdir /root/crypt /mnt/crypt
  # mount -t ecryptfs /root/crypt /mnt/crypt
  # mknod /mnt/crypt/c0 c 0 0
  # umount /mnt/crypt
  # mount -t ecryptfs /root/crypt /mnt/crypt
  # ls -l /mnt/crypt

This patch fixes it by adding a check similar to directories and
symlinks.

      ide-disk: workaround for buggy HPA support on ST340823A (take 3) · b0244a00
      Bartlomiej Zolnierkiewicz authored 
      This disk reports total number of sectors instead of maximum sector address
in response to READ_NATIVE_MAX_ADDRESS command and also happily accepts
SET_MAX_ADDRESS command with the bogus value.  This results in +1 sector
capacity being used and errors on attempts to use the last sector.

...
hdd: Host Protected Area detected.
        current capacity is 78165360 sectors (40020 MB)
        native  capacity is 78165361 sectors (40020 MB)
hdd: Host Protected Area disabled.
...
hdd: reading: block=78165360, sectors=1, buffer=0xc1e63000
hdd: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdd: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=78165360, sector=78165360
...

Add hpa_list[] table and workaround the issue in idedisk_check_hpa().

v2:
* Add missing export and improve patch description a bit.

v3:
* Add list termination.  (From Mikko)

Fixes kernel bugzilla bug #8816.

Thanks to Mikko for investigating the issue and helping with this patch.

      hpt34x: fix CONFIG_HPT34X_AUTODMA=n handling · 76e1faa7
      Bartlomiej Zolnierkiewicz authored 
      Programming DMA mode may destroy current PIO mode setting so if
CONFIG_HPT34X_AUTODMA=n (the default case) make ide_tune_dma() fail
early by disabling all host DMA masks and re-tune PIO mode.

This fix doesn't help with the driver being broken but is needed
for some other changes.
