e6be763f63 [BNX2]: Fix bug in bnx2_nvram_write().
The bug was a bogus pointer being passed to kfree().  The pointer was
incremented in the write loop and then passed to kfree().

The fix is to use align_buf to save the original address.

2a2f11c227 NetLabel: correct CIPSO tag handling when adding new DOI definitions
The current netlbl_cipsov4_add_common() function has two problems which are
fixed with this patch.  The first is an off-by-one bug where it is possibile to
overflow the doi_def->tags[] array.  The second is a bug where the same
doi_def->tags[] array was not always fully initialized, which caused sporadic
failures.

fea5f1e196 Revert "[PATCH] x86-64: Try multiple timer variants in check_timer"
This reverts commit b026872601, which has
been linked to several problem reports with IO-APIC and the timer.
Machines either don't boot because the timer doesn't happen, or we get
double timer interrupts because we end up double-routing the timer irq
through multiple interfaces.

See for example

	http://lkml.org/lkml/2006/12/16/101
	http://lkml.org/lkml/2007/1/3/9
	http://bugzilla.kernel.org/show_bug.cgi?id=7789

about some of the discussion.

Patches to fix this cleanup exist (and have been confirmed to work fine
at least for some of the affected cases) and we'll revisit it for
2.6.21, but this late in the -rc series we're better off just reverting
the incomplete commit that caused the problems.

d98f923714 [MIPS] pnx8550: Fix write_config_byte() PCI config space accessor
There's a serious typo in the function:
  arch/mips/pci/ops-pnx8550.c:write_config_byte()

The parameter passed to the function config_access() is PCI_CMD_CONFIG_READ
instead of PCI_CMD_CONFIG_WRITE. This renders any attempts to write
a single byte to the PCI configuration registers useless.

This problem does not exist for write_config_word() nor write_config_dword().

This problem has been there since kernel v2.6.17 and is still there
as of kernel v2.6.19.1.

6020dff092 [ARM] Resolve fuse and direct-IO failures due to missing cache flushes
fuse does not work on ARM due to cache incoherency issues - fuse wants
to use get_user_pages() to copy data from the current process into
kernel space.  However, since this accesses userspace via the kernel
mapping, the kernel mapping can be out of date wrt data written to
userspace.

This can lead to unpredictable behaviour (in the case of fuse) or data
corruption for direct-IO.

This resolves debian bug #402876

a6f36be326 [ARM] pass vma for flush_anon_page()
Since get_user_pages() may be used with processes other than the
current process and calls flush_anon_page(), flush_anon_page() has to
cope in some way with non-current processes.

It may not be appropriate, or even desirable to flush a region of
virtual memory cache in the current process when that is different to
the process that we want the flush to occur for.

Therefore, pass the vma into flush_anon_page() so that the architecture
can work out whether the 'vmaddr' is for the current process or not.

d63b70902b [PATCH] fix garbage instead of zeroes in UFS
Looks like this is the problem, which point Al Viro some time ago:

ufs's get_block callback allocates 16k of disk at a time, and links that
entire 16k into the file's metadata.  But because get_block is called for only
a single buffer_head (a 2k buffer_head in this case?) we are only able to tell
the VFS that this 2k is buffer_new().

So when ufs_getfrag_block() is later called to map some more data in the file,
and when that data resides within the remaining 14k of this fragment,
ufs_getfrag_block() will incorrectly return a !buffer_new() buffer_head.

I don't see _right_ way to do nullification of whole block, if use inode
page cache, some pages may be outside of inode limits (inode size), and
will be lost; if use blockdev page cache it is possible to zero real data,
if later inode page cache will be used.

The simpliest way, as can I see usage of block device page cache, but not only
mark dirty, but also sync it during "nullification".  I use my simple tests
collection, which I used for check that create,open,write,read,close works on
ufs, and I see that this patch makes ufs code 18% slower then before.

f2e12bb272 [PATCH] Check for populated zone in __drain_pages
Both process_zones() and drain_node_pages() check for populated zones
before touching pagesets.  However, __drain_pages does not do so,

This may result in a NULL pointer dereference for pagesets in unpopulated
zones if a NUMA setup is combined with cpu hotplug.

Initially the unpopulated zone has the pcp pointers pointing to the boot
pagesets.  Since the zone is not populated the boot pageset pointers will
not be changed during page allocator and slab bootstrap.

If a cpu is later brought down (first call to __drain_pages()) then the pcp
pointers for cpus in unpopulated zones are set to NULL since __drain_pages
does not first check for an unpopulated zone.

If the cpu is then brought up again then we call process_zones() which will
ignore the unpopulated zone.  So the pageset pointers will still be NULL.

If the cpu is then again brought down then __drain_pages will attempt to
drain pages by following the NULL pageset pointer for unpopulated zones.

6929da4427 [PATCH] hpt37x: Two important bug fixes
The HPT37x driver very carefully handles DMA completions and the needed
fixups are done on pci registers 0x50 and 0x52.  This is unfortunate
because the actual registers are 0x50 and 0x54.  Fixing this offset cures
the second channel problems reported.

Secondly there are some problems with the HPT370 and certain ATA drives.
The filter code however only filters ATAPI devices due to a reversed type
check.
