This patch adds 5 more FC transport host attributes in support of HBAAPI.

This patch deprecates the use of device_for_each_child() with stargets.
The reasoning behind this is due to issues regarding:
      Semaphores that device_for_each_child() takes
      Implicit assumptions that each child is an sdev device.

The patch adds a new helper function, starget_for_each_device(), and
replaces all previous uses of device_for_each_child().

There are a few spots in qla1280.c that don't need a full PCI write flush
to the device, but rather a simple write ordering guarantee.  This patch
changes some of the PIO reads that cause write flushes into mmiowb calls
instead, which is a lighter weight way of ensuring ordering.

This is really part of the earlier changeset from David to add the

Er, no it's not. But perhaps it should be...

Ingo presumably didn't notice that ppc64 already had a functional
_raw_read_trylock when he added the #define to use the generic
version.  This just removes the #define so we use the ppc64-specific
version again.

Currently we only print the default io scheduler if the kernel chooses,
not if the user/bootloader has specified one. This patch saves the extra
line in dmesg but always notified of the default choice by appending
(default) to that line:

	..
	io scheduler noop registered
	io scheduler anticipatory registered
	io scheduler deadline registered
	io scheduler cfq registered (default)
	..

This enables it only for debug kernels, and also makes sure
that if some external module is still broken, we don't leave
the mmap-sem locked after warning about it.

It seems to be general consensus that its safer to require all do_brk() callers
to grab mmap_sem, and have do_brk to warn otherwise. This is what the following
patch does.

Similar version has been changed to in v2.4.
Signed-off-by: Linus Torvalds <torvalds@osdl.org>

We had all the locking right, but we didn't check whether one of the
threads now no longer needed to expand, so we could incorrectly _shrink_
the stack in the other thread instead (not only causing segfaults, but
since we didn't do a proper unmap, we'd possibly leak pages too).

So re-check the need for expand after getting the lock.

Noticed by Paul Starzetz.

Fix a long standing bug: numa=off only worked as last argument on
the command line.

I found bugs on error handlings in the functions arround the ext3 file
system, which cause inadequate completions of synchronous write I/O
operations when disk I/O failures occur.  Both 2.4 and 2.6 have this
problem.

	I carried out following experiment:

1.  Mount a ext3 file system on a SCSI disk with ordered mode.
2.  Open a file on the file system with O_SYNC|O_RDWR|O_TRUNC|O_CREAT flag.
3.  Write 512 bytes data to the file by calling write() every 5 seconds, and
     examine return values from the syscall.
     from write().
4.  Disconnect the SCSI cable,  and examine messages from the kernel.

After the SCSI cable is disconnected, write() must fail.  But the result
was different: write() succeeded for a while even though messages of the
kernel notified SCSI I/O error.

By applying following modifications, the above problem was solved.

One bios assigns a small window for i/o access to yenta bridges.  But there
are Cardbus cards that needs lots of i/o ports.  yenta usually honors the bios
selected values, except if the bios choice is clearly invalid.  The patch
