The obvious patch to fix compiler warning when compiled with RH gcc 2.96
(and probably others too).

Finally, this changes set_bit et al. to take a "unsigned long *" on
ppc and i386.  This will make the world a better place.

Please forward patches for any warnings which crop up in random code
to trivial@rustcorp.com.au.

We have to include linux/bitops.h for arch using generic_xxx().

The following patch changes <asm/bitops.h> of include/linux/* to
<linux/bitops.h>.

Note patch compiles but is otherwise untested as no kernel after 2.5.7
boots on my 2.5 box due to IDE hanging the box hard during device
discovery. )-:

- Don't abuse the sense field for passing failed packet_commands in struct
   packet_command use a new field instead.

- Apply minor bits forwarded by Dave Jones to me.

- Fix ide_raw_taskfile() to flag the ar used there to be no subject of free_req
   list management. This solvs the "hang after /proc/ide read" problem, which
   was in fact a memory corruption problem.

- Consolidate ide_choose_drive() and choose_drive() in to one function.

- Remove sector data byteswpapping support. Byte-swapping the data is supported
   on the file-system level where applicable.  Byte-swapped interfaces are
   supported on a lower level anyway. And finally it was used inconsistently.

- Eliminate taskfile_input_data() and taskfile_output_data(). This allowed us
   to split up ideproc and eliminate the ugly action switch as well as the
   corresponding defines.

- Remove tons of unnecessary typedefs from ide.h

- Prepate the PIO read write code for soon overhaul.

- Misc small bits here and there :-).

USB kaweth driver updates

	- fixed race between close and disconnect
	- disconnect bug
	- add link state reporting
	- fix an urb reference counting bug
	- fix probe oopsability on oom
	- groundwork for atomic pool depletion
	- cosmetic changes

This removes gratuitous & operators in front of USB's
dev->bus->devmap.devicemap and state->unitbitmap, for bitops.

This just makes it so it doesn't warn when set_bit et. al take a
long...

No object code changes,
Rusty.

Create "export_operations" interface for filesystems to describe
whether and how they should be exported.

- add new field in struct super_block "s_export_op" to describe
  how a filesystem is exported (i.e. how filehandles are mapped to
  dentries).
- New module: fs/exportfs for holding helper code for mapping between
  filehandles and dentries
- Change nfsd to use new interface if it exists.
- Change ext2 to provide new interface
- Add documention to filesystems/Exporting

If s_export_op isn't set, old mechanism still works, but it is
planned to remove old method and only use s_export_op.

Prepare for new export_operations interface (for filehandle lookup):

 - define d_splice_alias and d_alloc_anon.
 - define shrink_dcache_anon for removing anonymous dentries
 - modify d_move to work with anonymous dentries (IS_ROOT dentries)
 - modify d_find_alias to avoid anonymous dentries where possible
   as d_splice_alias and d_alloc_anon use this
 - put in place infrastructure for s_anon allocation and cleaning
 - replace a piece of code that is in nfsfh, reiserfs and fat
   with a call to d_alloc_anon
 - Rename DCACHE_NFSD_DISCONNECTED to DCACHE_DISCONNECTED
 - Add documentation at Documentation/filesystems/Exporting

Advansys SCSI driver update:
 - locking fixes
 - handle the "address" -> "page+offset" switch

Made urb allocation dynamic, as the USB core needs this now.

USB pegasus and rtl8150 fixes and improvements

pegasus:
	- using preallocated skb thus avoiding memcpy in the receive path;
	- tasklet used to handle failed skb allocations and Rx urb submission;
	- Lindent run on the result.

rtl8150:
	- better tasklet handling and a few races fixed;
	- introducing new flag for Rx urb resubmission;
	- GFP_KERNEL to GFP_ATOMIC flag change in Tx path.

A few (anal) comment cleanups and additions in relationship to the new
task cpu affinity syscalls.  All no brainers.

This fixes the mpparse.c clobbering the last ACPI patch did. Martin, look
OK? Again, my apologies.

This fixes a race in migration_thread which results in a deadlock on
boot for some SMP systems.  The fix is to to disable preemption inside
of set_cpus_allowed.

Andrew Morton first noticed the problem and provided the following patch
a few weeks back.  I was not affected until the recent migration_init
fix, for some odd reason.  Neither Andrew nor I think this is actually
kernel preemption's fault but perhaps a race in the tricky behavior of
the migration code.

This patch is the start of the cleanup of the fbdev layer. It has been
approved by Geert and has been tested for some time in the Dave Jones
tree.

Remove localy defined wait queues and use wait queues
in tty structure of same function. This matches the
n_tty.c behavior.

Handle pty hangup when blocked on read.

These 2 changes fix use of n_hdlc with PPPoATM and
are mirror changes included in 2.4.19-pre

patch to update virt_to_bus functions and remove version depedent #ifdef
statements

This is originally from Andrew in the 2.4 series, please apply for 2.5
as well.

Fix oops in st_open..

We've seen this in several other drivers, most recently the indydog one.
  If two simultaneous opens occur, they race, they device gets opened
twice, blah, blah, blah.  Using atomic bitops fixes this.  The BKL is
not needed.

This patch adds #include <linux/threads.h> to include/linux/smp.h,
because it (smp.h) needs the definition of NR_CPUS.  (It so happens
that include/asm-i386/smp.h includes <linux/threads.h>, but IMHO
include/linux/smp.h shouldn't rely on that).

This is needed to for 2.5.7 FAT to build on ARM.

Include fixes to allow ALSA to compile.

On the swap_out() path, the radix-tree pagecache is allocating its
nodes with PF_MEMALLOC set, which allows it to completely exhaust the
free page lists(*).  This is fairly easy to trigger with swap-intensive
loads.

It would be better to make those node allocations fail at an earlier
time.  When this happens, the radix-tree can still obtain nodes from its
mempool, and we leave some memory available for the I/O layer.
(Assuming that the I/O is being performed under PF_MEMALLOC, which it
is).

So the patch simply drops PF_MEMALLOC while adding nodes to the
swapcache's tree.

We're still performing atomic allocations, so the rat is still biting
pretty deeply into the page reserves - under heavy load the amount of
free memory is less than half of what it was pre-rat.

It is unfortunate that the page allocator overloads !__GFP_WAIT to also
mean "try harder".  It would be better to separate these concepts, and
to allow the radix-tree code (at least) to perform atomic allocations,
but to not go below pages_min.  It seems that __GFP_TRY_HARDER will be
pretty straightforward to implement.  Later.

The patch also impements a workaround for the mempool list_head
problem, until that is sorted out.



(*) The usual result is that the SCSI layer dies at scsi_merge.c:82.
It would be nice to have a fix for that - it's going BUG if 1-order
allocations fail at interrupt time.  That happens pretty easily.

I've recently (actually, last month, but I had been a bit too busy
since then) come across a wee problem, in what I originally thought
was the VFAT code -- having `utf8' as one of the options, creating
UTF-8 file names on a VFAT partition mysteriously gains a couple of
(random) characters just after the UTF-8 escaped character: eg.
touch "fooCbar" where C is an UTF-8 escape sequence ends up creating
a file named "fooCRbar". (R being some random character.)

I eventually tracked it down to one line in fs/nls/nls_base.c -- the
UCS-2 (wchar_t) string pointer was being incremented too fast. After
consulting Ogawa Hirofumi-san on the subject, he mentioned that
include/linux/nls.h also needs to be changed for proper UTF-8
support in the NLS code.

 earlier bfs related email)

Missed a page->buffers -> page->private conversion.
Apologies..

This patch adds 5 help texts to arch/ia64/Config.help.  The texts were
obtained from Eric S.  Raymond's v2.97 Configure.help.

The patch to the PnP BIOS driver that was in 2.5.7-dj and which
went into 2.5.8-pre1 did not include Brian Gerst's SMP fix.

 - fixe compile error (scatterlist::address replaced)
 - simplify obtaining ram disk memory (using vmalloc)
 - improve SCSI INQUIRY and MODE SENSE support

 - allow detection of pre-existing disk geometry

- Updated fs/devfs/util.c to fix shift warning on 64 bit machines
  Thanks to Anton Blanchard <anton@samba.org>

- Updated README from master HTML file

- Expand configure help options a bit
- Fix xconfig bug
- Decrease queue depth if a command takes too long to complete
- Test master/slave stuff. It works, but one device can heavily starve
   another. This is the simple approach right now, means that one device
   will wait until the other is completely idle before starting any
   commands This is not necessary since we can have queued commands on
   both devices at the same time. TODO.
- Add proc output for oldest command, just for testing.
- pci_dev compile fixes.
- Make sure ide-disk doesn't BUG if TCQ is not used, basically this was
   fixed by off-loading the using_tcq setting to ide-tcq.
- Remove warning about 'queued feature set not supported'
- Abstract ide_tcq_wait_dataphase() into a function
