Issue discovered by Ricky Beam (jfbeam@bluetronic.net).

This patch includes quite a few changes and updates for the shwdt driver (which
brings it in sync with LinuxSH CVS HEAD). This fixes up support for the SH-2,
and also fixes up some timer brain-damage.

This patch updates the sh-specific hd64465 pcmcia driver for the new API, as
well as fixing up some other issues (such as remap_page_range() abuse -- we
remap through P3 area instead) which caused it not to compile. Changes by
Dominik Brodowski and myself.

Here's an update for pvr2fb (with a patch this time), which makes it compile
again.

ppc64 machines can have PCI bus numbers larger than 8 bits, but it looks
like pci_device_to_OF_node already handles this case, in both 2.4 and
2.5.

We just need the space to store them.

This solves the unresolved symbol problem with modular intermezzo.  Also
update the MAINTAINERS entry.

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.

From Flavio B. Leitner. <fbl@netbank.com.br>

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.

From Matthew Wilcox <willy@debian.org>.

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.

into tetrachloride.(none):/mnt/raid/src/kernel/2.5/agpgart

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.
