Michael S. Tsirkin 608d8268be IB/mthca: Fix data corruption after FMR unmap on Sinai
In mthca_arbel_fmr_unmap(), the high bits of the key are masked off.
This gets rid of the effect of adjust_key(), which makes sure that
bits 3 and 23 of the key are equal when the Sinai throughput
optimization is enabled, and so it may happen that an FMR will end up
with bits 3 and 23 in the key being different.  This causes data
corruption, because when enabling the throughput optimization, the
driver promises the HCA firmware that bits 3 and 23 of all memory keys
will always be equal.

Fix by re-applying adjust_key() after masking the key.

Thanks to Or Gerlitz for reproducing the problem, and Ariel Shahar for
help in debug.

Andi Kleen 08269c6d38 [PATCH] x86: Fix gcc 4.2 _proxy_pda workaround
Due to an over aggressive optimizer gcc 4.2 cannot optimize away _proxy_pda
in all cases (counter intuitive, but true).  This breaks loading of some

The earlier workaround to just export a dummy symbol didn't work unfortunately
because the module code ignores exports with 0 value.

Trond Myklebust 5a6d41b32a NFS: Ensure PG_writeback is cleared when writeback fails
If the writebacks are cancelled via nfs_cancel_dirty_list, or due to the
memory allocation failing in nfs_flush_one/nfs_flush_multi, then we must
ensure that the PG_writeback flag is cleared.

Also ensure that we actually own the PG_writeback flag whenever we
schedule a new writeback by making nfs_set_page_writeback() return the
value of test_set_page_writeback().
The PG_writeback page flag ends up replacing the functionality of the
PG_FLUSHING nfs_page flag, so we rip that out too.

James Bottomley 6e3b2bbb19 [SCSI] 3w-xxxx: fix oops caused by incorrect REQUEST_SENSE handling
3w-xxxx emulates a REQUEST_SENSE response by simply returning nothing.
Unfortunately, it's assuming that the REQUEST_SENSE command is
implemented with use_sg == 0, which is no longer the case.  The oops
occurs because it's clearing the scatterlist in request_buffer instead
of the memory region.

This is fixed by using tw_transfer_internal() to transfer correctly to
the scatterlist.

Olaf Kirch d791d413fd DVB: dvb-usb-remote - fix oops when changing keymap
DVB USB remotes do not support changing keycode maps but set
input_dev->keycodesize and input_dev->keycodemax without setting
input_dev->keycode. This causes kernel oops when user tries to
look up (or change) current keymap.

While the proper fix would be to make remotes handle keymap changes
we'll just remove keycodemax and keycodesize initialization so
EVIOCGKEYCODE and EVIOCSKEYCODE will simply return -EINVAL.

The device name strings in the arp table entries are not guarenteed

Jerome Borsboom 279e172a58 [VLAN]: Allow VLAN interface on top of bridge interface
When a VLAN interface is created on top of a bridge interface and 
netfilter is enabled to see the bridged packets, the packets can be 
corrupted when passing through the netfilter code. This is caused by the 
VLAN driver not setting the 'protocol' and 'nh' members of the sk_buff 
structure. In general, this is no problem as the VLAN interface is mostly 
connected to a physical ethernet interface which does not use the 
'protocol' and 'nh' members. For a bridge interface, however, these 
members do matter.

Jeff Mahoney c3724b129b [PATCH] autofs4: fix race in unhashed dentry code
Commit f50b6f8691 introduced a race in
autofs4 between autofs_lookup_unhashed() and autofs_dentry_release().

autofs_dentry_release() ends up clearing the ->dentry and ->inode members
of autofs_info before removing it from the rehash list.  The list is
protected by the rehash lock in both functions, but since
autofs_dentry_release() starts tearing the autofs_info struct down before
removing it from the list, autofs_lookup_unhashed() can get a autofs_info
with a NULL dentry.

This patch moves the clearing of ->dentry and ->inode after the removal
from the rehash list.

Roland McGrath 1d51c69fb6 [SPARC]: avoid CHILD_MAX and OPEN_MAX constants
I don't figure anyone really cares about SunOS syscall emulation, and I
certainly don't.  But I'm getting rid of uses of the OPEN_MAX and CHILD_MAX
compile-time constant, and these are almost the only ones.  OPEN_MAX is a
bogus constant with no meaning about anything.  The RLIMIT_NOFILE resource
limit is what sysconf (_SC_OPEN_MAX) actually wants to return.

The CHILD_MAX cases weren't actually using anything I want to get rid of,
but I noticed that they are there and are wrong too.  The CHILD_MAX value
is not really unlimited as a -1 return from sysconf indicates.  The
RLIMIT_NPROC resource limit is what sysconf (_SC_CHILD_MAX) wants to return.

David S. Miller 2f3a2efd85 [SPARC64]: Fix SBUS IOMMU allocation code.
There are several IOMMU allocator bugs.  Instead of trying to fix this
overly complicated code, just mirror the PCI IOMMU arena allocator
which is very stable and well stress tested.

I tried to make the code as identical as possible so we can switch
sun4u PCI and SBUS over to a common piece of IOMMU code.  All that
will be need are two callbacks, one to do a full IOMMU flush and one
to do a streaming buffer flush.

This patch gets rid of a lot of hangs and mysterious crashes on SBUS
sparc64 systems, at least for me.
