A very long time ago ext3_fill_super() was beng called under the VFS's
lock_super(), and it had to drop that lock for deadlock avoidance reasons.

But the VFS was later changed to not take lock_super() across ->fill_super(),
so we're upping a non-downed semaphore.

Just take it out.

Redo the (strange) layout of some of Roger's comments.

No need to check root->rnode in the loop. In the loop it remains nonzero.

We need to validate that the address and length of a MAP_FIXED request are
suitable for hugetlb pages.

The amd74xx IDE driver in 2.5.59 has support for the nforce IDE controller,
but not explicitly for the nforce2 IDE controller (which has a different PCI
ID, which is in the kernel already).  I'm not sure if the nforce and nforce2
controllers are identical, but I made a small patch that made the amd74xx
driver recognize the nforce2 IDE, and it boots for me, seems to work fine, as
my drives were tuned to their highest transfer rate automatically (udma5).

I don't know if this patch is proper or correct, but it Works for Me [tm].
Patch is attached.

This was found by the Standford Checker.
The LogicalDeviceNumber bad range test was changed from > to >=
I also replaced a couple of panic() calls with error messages,
since panic-ing seemed a little extreme.

journal_try_start() is a function which nonblockingly attempts to open a JBD
transaction handle.  It was added a long time ago when there were concerns
that ext3_writepage() could block kswapd for too long.

It was never clearly necessary.

So the patch throws it all away and just calls the blocking journal_start()
from ext3_writepage().

The task_struct->sig -> task_struct->signal bits.

Mikulas Patocka <mikulas@artax.karlin.mff.cuni.cz> points out a bug in
ll_rw_block() usage.

Typical usage is:

	mark_buffer_dirty(bh);
	ll_rw_block(WRITE, 1, &bh);
	wait_on_buffer(bh);

the problem is that if the buffer was locked on entry to this code sequence
(due to in-progress I/O), ll_rw_block() will not wait, and start new I/O.  So
this code will wait on the _old_ I/O, and will then continue execution,
leaving the buffer dirty.

It turns out that all callers were only writing one buffer, and they were all
waiting on that writeout.  So I added a new sync_dirty_buffer() function:

	void sync_dirty_buffer(struct buffer_head *bh)
	{
		lock_buffer(bh);
		if (test_clear_buffer_dirty(bh)) {
			get_bh(bh);
			bh->b_end_io = end_buffer_io_sync;
			submit_bh(WRITE, bh);
		} else {
			unlock_buffer(bh);
		}
	}

which allowed a fair amount of code to be removed, while adding the desired
data-integrity guarantees.

UFS has its own wrappers around ll_rw_block() which got in the way, so this
operation was open-coded in that case.

This removes lots of annoying problems trying to prevent both modules
from being loaded, and also shares quite a bit of code.
CONFIG_AGP3 will disable AGP3 mode operation of KT400s.

Based upon information from VIA, this also adds a bunch of placeholder
entries that will get filled in over time when they have been proven
to work with the code with no extra modification.

  
The AGP3 spec allows for >1 AGP bus. This is the first of several patches
from Jeff Hartmann towards a context-using agp_bridge, by replacing
agp_bridge.foo accesses with agp_bridge->foo accesses. For now, there
should be no functional differences, as there is still only a single
agp_bridge_data struct defined.

Most of the instances of <module>.o in Kconfig files have had the ".o"
extension trimmed.  This change came from GertJan Spoelman through Rusty
"Trivial" Russell.

However, there are a few files that didn't get trimmed.  This brings
them line with the rest of the tree.

so that there isn't any window for running before the signal
handler has been invoced.

from certain states.

This simplifies "default_wake_function()", and makes it possible for
signal handling to wake up only the processes it _should_ wake up
without races.

  OK, here is a new patch, I edited the old patch and took out the .ko's
  so now the extension is trimmed instead.

  On 64-bit platforms, issuing write(2) with buffer larger than
  2GB will return -1 and broken errno (such as 2147483640)
  Requested data itself is written correctly.

  That is because generic_file_write() and other relating functions
  store 'ssize_t written' into 'int err'. Written byte is trimmed to
  int and then sign-extended to a negative ssize_t value, which
  wrongly indicates an error.

  (On 64bit platform, current glibc defines SSIZE_MAX as 'LONG_MAX')
