Patch from Hugh Dickins <hugh@veritas.com>

swap_readpage and swap_writepage forgot
to unlock_page if get_swap_bio failed.

Patch from Hugh Dickins <hugh@veritas.com>

On some architectures (cachetlb.txt gives HyperSparc as an example)
it is essential to flush_cache_page while pte is still valid: the
rmap VM diverged from the base 2.4 VM before that fix was made,
so this error has crept back into 2.5.

Patch below applies to 2.5.47 or 2.5.47-mm1 - needs more work over
shared pagetables, but they've silently fallen out of 2.5.47-mm1:
oversight?  I'll send Alan the equivalent for 2.4-ac shortly.

(I wonder, what happens if userspace now modifies the page
after the flush_cache_page, before the pte is invalidated?)

Patch from Andreas Gruenbacher <agruen@suse.de>

Add a gfp_mask parameter to the free() callback so that the callback can
safely do I/O, etc. The free callback can now also fail.  This will be
needed by reiserfs.

The order of entries on the cache entry lru is reversed so that
list_for_each_safe() can be used. Several helper functions that don't
make the code any better are removed. Finally, a couple of cosmetic
things.

From Badari.

bio_add_page returns zero on failure - we need to propagate that
to the dio_bio_add_page() caller.

This patch removes all the wait_queue handling code from sched.h and puts
it in wait.h with the rest of the wait_queue handling code.  Note that
sched.h must continue to include wait.h for the wait_queue_head_t embedded
in struct task.  However there may be files which only need wait.h now.

It really makes no sense to have request_irq and free_irq in sched.h
Let's move them to interrupt.h instead.  Note that I also remove sched.h
from interrupt.h since it's not needed.

A minor removal of 6 function definitions from sched.h.  They clearly
fit better in file.h.  All users of these functions already include file.h.
And none of them included sched.h directly...

This patch from William Lee Irwin III privatizes __d_path() to dcache.c,
uninlines d_path(), moves its declaration to dcache.h, moves it to
dcache.c, and exports d_path() instead of __d_path().

Grrr...  Two bugs in a patch that had moved md setup to late boot:

a) we need md_run_setup() run before parsing root name.
b) it's create_dev("/dev/md0",...), not create_dev("md0",...) ;-/

Still not safe (we use __MOD_INC_USE_COUNT in paride.c; old code has
MOD_INC_USE_COUNT in protocol drivers), but that takes crap in one
place.

	->owner added
	paride.c grabs/releases it if if present
	->proto_init() became empty for almost everything
	->proto_release() <<--->>
	->proto_init() returns int now (the only case where we do have a
	  non-empty ->proto_init() needed that all along).  paride.c
	  taught to deal with that.

dasd_proc.c : should be using ->owner instead of MOD_..._USE_COUNT in
->open()/->release().

s390/char/tape.c, s390/char/tapechar.c, usb/image/scanner.c,
intermezzo/psdev.c: ditto

intermezzo/super.c: they forgot to remove MOD_INC_USE_COUNT from the
..._fill_super()

binfmt_som.c: ->load_binary() and ->load_library() don't need
MOD_INC_USE_COUNT, since ->module is correctly set.

devfs_register_tape() returns the number it had assigned to tape.

new helper: devfs_unregister_tape(number) - removes symlink created by
devfs_register_tape()

devfs_register_tape() doesn't use devfs_auto_unregister() anymore.

devfs_register_tape() gets devfs entry of directory, instead of that of
a random file in that directory.

users updated

dm-ioctl.c does, er, interesting things to figure out the name of devfs
node it had just created.  Cleaned up.

dv1394.c piles amazing amounts of crap around its devfs entries.
Probably a result of times before devfs_find_and_unregister()...

In any case, code switched to use of devfs_find_and_unregister(),
crapectomy performed...

- Improved file cleanup code

- A more uniform poll queueing interface with tips from Manfred

- The f_op->poll() is done outside the irqlock to maintain compatibility
	with existing drivers that assume to be called with irq enabled

- Moved event mask setting inside ep_modify() with tips from John

- Fixed locking to fit the new "poll() outside the lock" approach

- Bufferd userspace event delivery to reduce irq_lock/irq_unlock switching
	rate and to reduce the number of __copy_to_user()

- Comments added

There's a long standing bug in blk_recount_segments(). Clustering means
physical segment colascing, not hardware segment colascing. This
basically means that we are mapping more segments than here than the bio
+ requests contains, and this causes a bug in the SCSI layer for host
adapters that have CLUSTERING enabled.

This patch makes sure that we are clustering physical segments
correctly, and correctly accounting hardware segments. Please apply.

I thought I'd send the results of some experimentation of mine getting
an MGE UPS (Evolution) to talk to 2.5 ... basically it behaved after
some patches, though the "hidups" driver didn't.  They're all attached:

   - "hiddev-1.patch"  ... The default queue size was so small that this
     low-speed device couldn't queue up about 110 control requests
     (that many reports to check!) during init.

   - "hiddev-2.patch" ... Makes hid debug output more useful by
      (a) making it compile again;
      (b) adding lots of "Power Device" and "Battery System" reports,
          and putting all that data into the readonly data section;
      (c) actually printing the usage strings, if they're known;
      (d) printing a message when neither input nor hiddev claim
          the device ... likely something's wrong, like someone
          didn't configure in input subsystem or hiddev support.

   - "hiddev-3.patch" ... Teaches hiddev to expose the physical ID
     just like the input event framework does.  Useful to help sort
     out which UPS is which, so you won't power down the wrong set
     of servers by accident.

This fixes a problem from Chris' patch, letting the driverfs files
work again.  The root cause was a duplicate "parent_dev" field,
now gone.  This also adds minor cleanup in the hcd glue, renaming
the value being duplicated as the "controller" that the HCD is
driving.  (A "parent" should rarely be used, but the "controller"
has reasonable uses all over the place ... like in dev_dbg calls!)
It's initted by the PCI bus glue, or by the SA-1111 bus glue.

Also makes some OHCI debug messages appear only when VERBOSE debug
is (manually) enabled.  This was self-defense, otherwise running
the link/unlink "usbtest" cases could fill up the log filesystem
(with debug enabled).
