send_IPI_self is needed to resend irqs with IRQ_PENDING status when
enabled.

Checked with Ingo, and it's in 2.4-ac for some time.

This should fix ide lost interrupts on UP with IO-APIC

Ide trigers it this way:
 - disable_irq
 - do stuff that triggers IRQ.
 - irq is IRQ_PENDING
 - enable_irq
 - IRQ is lost, needs to be resend.

I'll send the patch to fixup IDE disable_irq logic to Bart.

Fix a memory leak and an unchecked return code in the busmouse driver.

From Daniele Bellucci <bellucda@tiscali.it>.

Check the copy_to_user() return code in read_profile().

From Jorn Engel <joern@wohnheim.fh-wedel.de> and Randy Dunlap.

It reduces stack usage in the WAN router by about 0x500 bytes
(from 0x520 to 0x24 when I did it in April).

This fixes this warning:

  syncppp.c:165: warning: function declaration isn't a prototype

by adding "void" as the function parameter list.

This fixes one place where I missed the replacing dcache_lock with
vfsmount_lock in put_namespace().

Tested with CLONE_NEWNS flag also.

First "test" kernel. Same naming we used for 2.4.0 - there it took
from May to December to get to the real version. Let's see if we
can do it faster this time.

Switching the PCMCIA interrupts from serial PCI interrupts to parallel
PCI interrupts causes machines to hang solid.  If we leave such setups
well alone, and only change the interrupt mode of parallel PCI systems
between PCI+ISA and PCI only.

The accounting works now, but I still think this last bit should be
added as well.  This makes absolutely sure we only account fs requests,
at both ends. Better safe than sorry.

The recent change from Andi breaks here: tmp.name is user pointer, not
array in __sysctl_args, and so it is better to access it through
copy_from_user instead of directly.

Didn't turn up anything particularly nasty, but it does clean up
usage of a few types that are passed around.
- Do the casts in the ioctl handler instead.
- Remove unused variables.
- __user annotations.

Again, untested in AGP3.x mode.

This (and a few other SiS chipsets) are AGP 3 compliant. AFAIK, none of
these have been tested in AGP3 mode, but they should work just fine in
AGP2.x mode at least.
