While helping someone to submit a patch to the stable branch, I noticed
that the stable branch is not listed in the MAINTAINERS file.  This was
after I went there to look for the email addresses for the stable branch
list (stable@kernel.org).

This patch adds the stable branch to the maintainers file so that people
can find where to send patches when they have a fix for the stable team.

[S390] fix futex_atomic_cmpxchg_inatomic

futex_atomic_cmpxchg_inatomic has the same bug as the other
atomic futex operations: the operation needs to be done in the
user address space, not the kernel address space. Add the missing
sacf 256 & sacf 0.

Currently I am doing lots of refactoring work in the dvb tree. This
bugfix became necessary to fix 2.6.17 whilst I was in the middle of this
work. Unfortunately after I tested the original code for the patch, I
generated the diff against the wrong tree (I accidentally used a tree
with part of the refactoring code in it). This resulted in the reported
compile errors because that tree (a) was incomplete, and (b) used
features which are simply not in the mainline kernel yet.

Many apologies for the error and problems this has caused. :(

Fix a bug identified by Zou Nan hai <nanhai.zou@intel.com>:

If the system is in state SYSTEM_BOOTING, and need_resched() is true,
cond_resched() returns true even though it didn't reschedule.  Consequently
need_resched() remains true and JBD locks up.

Fix that by teaching cond_resched() to only return true if it really did call
schedule().

cond_resched_lock() and cond_resched_softirq() have a problem too.  If we're
in SYSTEM_BOOTING state and need_resched() is true, these functions will drop
the lock and will then try to call schedule(), but the SYSTEM_BOOTING state
will prevent schedule() from being called.  So on return, need_resched() will
still be true, but cond_resched_lock() has to return 1 to tell the caller that
the lock was dropped.  The caller will probably lock up.

Bottom line: if these functions dropped the lock, they _must_ call schedule()
to clear need_resched().   Make it so.

Also, uninline __cond_resched().  It's largeish, and slowpath.

The Intel(R) PRO/1000 82572EI card is fully supported by 7.0.33-k2 and
onward.  Add the device ID so this card works with 2.6.17.y onward. This
device ID was accidentally omitted.

The inode number out of an NFS file handle gets passed eventually to
ext3_get_inode_block() without any checking.  If ext3_get_inode_block()
allows it to trigger an error, then bad filehandles can have unpleasant
effect - ext3_error() will usually cause a forced read-only remount, or a
panic if `errors=panic' was used.

So remove the call to ext3_error there and put a matching check in
ext3/namei.c where inode numbers are read off storage.

For files other than IFREG, nobh option doesn't make sense.  Modifications
to them are journalled and needs buffer heads to do that.  Without this
patch, we get kernel oops in page_buffers().
