All the other GART drivers display what they've found, so make this
one follow suit.

Offering the K7 GARTs on 64bit kernels causes sillyness, like reports of
"unrecognised device, try unsupported".  We don't want people to even try
that, so don't offer it in the first place.

There's really no good reason for offering any of the IA32 era GARTs on a
x86-64 64bit kernel. If Intel (or whoever) ever do an x86-64 clone, a new
gart driver will be started anyways, as has been done for amd-k8-agp.

This optioned saved just a handful of bytes, and uglied up the code 
quite a lot. Saving less than a page of memory is not as important as
maintainable code.

 - bad preprocessor test always tested true, even when it shouldn't.
 - annotate user pointers with proper annotations.

type evaluation.  This tags the system call interfaces in
fs/open.c, fs/dcache.c and mm/swapfile.c - and tags the path
walking helper functions.

It can miss an fput() if passed the fd of a file which has no ->mapping.

The included patch helps 3c59x to display the correct identification
string (3c592 and 3c597 were displayed as 3c590). It also gets rid of
the EISA_bus reference, which is not needed anymore since the driver
has been ported to the EISA probing API.

Update and clarify the incorrect commentary around task_lock()

From: "Martin J. Bligh" <mbligh@aracnet.com>

Fix the commentary around the address_space fields.

MS_ASYNC will currently wait on previously-submitted I/O, then start new I/O
and not wait on it.  This can cause undesirable blocking if msync is called
rapidly against the same memory.

So instead, change msync(MS_ASYNC) to not start any IO at all.  Just flush
the pte dirty bits into the pageframe and leave it at that.

The IO _will_ happen within a kupdate period.  And the application can use
fsync() or fadvise(FADV_DONTNEED) if it actually wants to schedule the IO
immediately.

(This has triggered an ext3 bug - the page's buffers get dirtied so fast
that kjournald keeps writing the buffers over and over for 10-20 seconds
before deciding to give up for some reason)

Missing brelse() in ext2/ext3 extended attribute code

The ext2 and ext3 EA implementations fail to release a buffer_head if
the inode that is being accessed is sharing EAs with another inode, and
an attribute is set to the same value that it has already, like so:

        $ touch f g
	$ setfattr -n user.test -v test f g
	# (Now, both f and g refer to the same EA block.)
	$ setfattr -n user.test -v test f

With the bug, an "invalidate: busy buffer" or "invalidate: dirty
buffer" message will be logged when the file system is unmounted. This
patch fixes the problem.

At the implementation level:

The code was assuming that ext3_xattr_cache_find cannot return the same
block the inode already is associated with, so testing for (old_bh !=
new_bh) would determine whether the old block is resued or an additional
bh is held. This is wrong if the EA block is used by multiple inodes (in
which case it stays in the cache), and the block isn't actually
modified.  Instead of testing for (old_bh != new_bh), the code now does
a get_bh() in the branch that keeps the old block, which assures that
new_bh now is either NULL or a handle that must be released at the end
of ext3_xattr_set_handle2().

This fixes a bug that might happen having a thread doing epoll_wait() with
another thread doing epoll_ctl(EPOLL_CTL_DEL) and close(). The fast check
inside eventpoll_release() is good to not effect performace of code not
using epoll, but it requires get_file() to be called ( that can be avoided
by dropping the fast check ). I opted to keep the fast check and to have
epoll to call get_file() before the event send loop. I tested it on UP and
2SMP with a bug-exploiting program provided by @pivia.com ( thx to them )
and it looks fine. I also update the 2.4.20 epoll patch with this fix :
