Remove /* SMP-safe */ comments before shmem_truncate and shmem_mknod:
don't know who or why put there, but they seem to imply that the rest
of shmem.c is unsafe.

Several simple speedups to tmpfs swapoff: without patch, swapoff of a
kernel tree in tmpfs might take take 2 minutes, with patch 4 seconds.
Inline search go no further than necessary; only search inode when it
has swapped pages; start next search from same inode; list in order.

(There's a "list_move_tail" in this patch: not available in 2.5.21,
but I believe you now have it in your ongoing tree.)

shmem_mknod should not update directory times if it cannot get an inode.

shmem_symlink was letting a long symlink overwrite its vfs_inode, now
included within struct shmem_inode_info - oops! and failed long symlink
inodes were freed but still left on the shmem_inodes list, causing oops
in swapoff at shutdown (if not earlier).

shmem_rename was not maintaining the correct link count on the
parent directories when a directory was moved from one to another.
This patch from Christoph Rohland <cr@sap.com>, already in 2.5-dj.

 - Bunch of cleanups by Bartlomiej (accounts for over a half of the patch):

    cmd64x.c:
	- kill SPLIT_BYTE() macro

	- misc cleanups

    cy82c693.c:
	- kill obsolete comments
	- clean cy82c693_tune_drive() and calc_clk()
	- misc cleanups

    hpt34x.c:
	- kill obsolete comment
	- kill SPLIT_BYTE()
	- kill hpt34x_clear_chipset()
	- simplify hpt34x_tune_drive()

    hpt366.c:
	- kill hpt_min_rev()
	- kill redundant hpt368_tune_chipset() and hpt374_tune_chipset()
	- fix badlists checking in config_chipset_for_dma()
	- misc cleanups

    pdc202xx.c:
	- clean registers decoding
	- clean pdc202xx_tune_chipset()
	- kill pdc202xx_udma_irq_status(), use generic udma_pci_irq_status()
	- rationalize pdc202xx_reset()
	- kill UDMA_SPEED_FLAG() and PDC_CLOCK() macros,
	  do it right by defining constants PDC_UDMA and PDC_CLK
	- kill init_high_16() inline, no need to hide internals
	- clean pdc202xx_init_chipset()
	- split ata66_pdc202xx() and pdc202xx_init_chipset()
	- clean config_chipset_for_dma()
	- misc cleanups

 - Fix plug in of CF cards. The previously used sub device driver attach method
   lookup was entirely hosed.

 - Enforce indentation style on ide-cs.c. Enable debugging there. (Makes the
   patch quite big...)

This makes the IO bitmap allocations a separately allocated structure,
shrinking the default task size.

We alloc it in sys_ioperm() and copy_thread() and frees in
exit_thread().  It also gets rid of the IO_BITMAP_SIZE+1 crap, as only
the tss actually needs the tail long, and we weren't copying it into the
bitmap anyways.

The utime and utimes should do exactly the smae permission check
according to SUSv3.
	"The effective user ID of the process shall match the owner of the file,
or has write access to the file or appropriate privileges to use this call
in this manner."

utimes when passed a NULL second argument would fail on a read only
file even if the file is owned by the caller.

The following comes from James Bottemley, as he updated the SCSI layer
to use the generic tagging.

Basically just put blk_queue_tag_request() into ll_rw_blk.c and name it
something more sane, blk_queue_find_tag(). In addition, remove REQ_CMD
requirement in blk_queue_start_tag() -- this is actually IDE specific
(we can only tag read/write requests there...), SCSI actually requires
everything to be tagged once enabled. It's replaced with a safety check
for an already tagged request.

This is a merge of the two things that are needed for the plugging as it
stands in 2.5.21. The first is fixing the locking to be both clearer and
safe (Andrew repeatedly broke the old version). The second is a few
changes that allow make_request_fn drivers to utilize plugging. This is
needed for umem and raid, for instance, that have their private
plugging.

Silly oversight - read_pages needs to pass the file *
down to ->readpage().

- If we're PF_MEMALLOC and BIO allocation failed, fall back to try
  to allocate a smaller BIO (from a different mempool)

- When writepages() gets confused, call a_ops->writepage()
  instead of going directly to block_write_full_page().  It
  gives the fs more flexibility, and XFS may want this.

It will need swapops.h for swp_entry().

Fix the order of inodes being marked dirty in a couple of corner cases.

The only impact of this bug is that the on-disk copies of i_version
might got out of sync for a directory, or that an error inserting an
inode into a directory might leave its i_nlinks incorrect on disk for a
short interval.  Neither problem will cause trouble for ext3 during
normal operation, but the nlink problem might cause e2fsck to emit
unnecessary warnings if we crash while the incorrect version of the
inode is in the journal.

Removes the put_iode optimisation.  It's racy, as
Chris pointed out.

ext3 will remount the fs readonly if it runs out of inode
space.  It shouldn't do that - it should just return -ENOSPC.

This allows compilation without ACPI_DEBUG defined.

This adds an export so that processor.o and thermal.o can be compiled as

A couple of targets were still in the main part of the Makefile,
even though they did not need .config to exist for execution.

Move them into the noconfig section of the Makefile, allowing them
to be executed before make *config.

amd7930_fn.h defined a static array, which however was only used in
one of the files which include amd7930_fn.h. So move the array to the
file where it is actually referenced.

While we're at it, do some more cleanup like removing the #defines
for BYTE,WORD and use u16,u8 instead - WORD was even wrongly defined
to unsigned int. Also, convert some macros to inlines etc.

The eicon header defined macros for byte, word, dword. Apart from that
not being a good idea in general, it did clash with the use of a parameter
called "word" in asm/signal.h. At some other place in the Eicon headers, 
there are also typedefs for these types, so the macros can simply go away.

The always-appreciated Stanford Checker found a memory leak in
net/socket.c :: sock_fasync.  It was a bit tricky since the memory was
only conditionally allocated, so must only conditionally be freed.

	This patch  fixes the Compaq WL210 problems I've been having.

The symptoms were that no interupts were ever received from the card;
the BIOS reported it had assigned INTA to IRQ 10; but the yenta
driver reported IRQ 17.

The fix is not to rely on the BIOS's initialisation of interrupt
routing in the TI1410, but to do it explicitly.

This may break laptops that actually use the parallel ISA IRQ
mechanism.
