This patch moves code out of fs/xattr.c:listxattr into a new function -
vfs_listxattr. The code for vfs_listxattr was originally submitted by Bill
Nottingham <notting@redhat.com> to Unionfs.
Sorry about that. The reason for this submission is to make the
listxattr code in fs/xattr.c a little cleaner (as well as to clean up
some code in Unionfs.)
Currently, Unionfs has vfs_listxattr defined in its code. I think
that's very ugly, and I'd like to see it (re)moved. The logical place
to put it, is along side of all the other vfs_*xattr functions.
Overall, I think this patch is benefitial for both kernel.org kernel and
Unionfs.

Cast to (void *) in request_irq() argument is stupid and

Use the new typedef for interrupt handler function pointers rather than
actually spelling out the full thing each time. This was scripted with the
following small shell script:
#!/bin/sh
egrep -nHrl -e 'irqreturn_t[ ]*[(][*]' $* |
while read i
do
echo $i
perl -pi -e 's/irqreturn_t\s*[(]\s*[*]\s*([_a-zA-Z0-9]*)\s*[)]\s*[(]\s*int\s*,\s*void\s*[*]\s*[)]/irq_handler_t \1/g' $i || exit $?
done

We should pass "wait_event_interruptible()" the wait-queue itself, not
the pointer to it. The magic macro will pointerize it internally.

This reverts commit 41550c5128.
Quoth Ben Herrenschmidt:
"Please revert this one for now. It seems to break G5s :( Looks like
PCI cells inside Apple IO ASICs don't have a PCI_INTERRUPT_LINE set.
I need to figure out a better fix."

Commit ca4aa09635 fixed waiting for the
structure to get initialised, but it is also possible to break out of
the loop while still in TASK_INTERRUPTIBLE.
Replace the whole thing by wait_event_interruptible, which is much more
readable, and doesn't suffer from these problems.

isa_no_iack_sc_device_interrupt() always gets get_irq_regs() as

All but two callers of handle_irq() pass get_irq_regs() as argument;
convert the remaining two, kill set_irq_regs() inside handle_irq().

callers of ->device_interrupt() do set_irq_regs() now; pt_regs argument
removed, remaining uses of regs in instances of ->device_interrupt()
are switched to get_irq_regs() and will be gone in the next patch.

Fallout from previous patch:
- actually add include/asm-m68k/irq_regs.h
- missed the prototype of sun3_sched_init()

read_trylock() is broken on sparc32 (doesn't build and didn't work
right, actually). Proposed fix:
- make "writer holds lock" distinguishable from "reader tries to grab
lock"
- have __raw_read_trylock() try to acquire the mutex (in LSB of lock),
terminating spin if we see that there's writer holding it. Then do
the rest as we do in read_lock().
Thanks to Ingo for discussion...
