346ca04d05 PCI: re-enable onboard sound on "MSI K8T Neo2-FIR"
On the "MSI K8T Neo2-FIR" board the BIOS disables the onboard
soundcard, if a second PCI soundcard is present.

This patch sets the korrect register bit to enable the onboard sound.

Removed old code in /drivers/pci/quirks.c that only checks for the
PCI-ID and fires on any Board with VIA 8237.

New code in /arch/i386/pci/fixup.c checks the DMI-tables and only runs
on the specific board.

b205f6b267 i386: add support for picopower irq router
Add support for PicoPower PT86C523 IRQ router to be used with the in-kernel
yenta driver for CardBus.  With this patch cardbus works on e.g.  Dell
Latitude XPi P150CD.

Initial patch for kernel 2.4 series by Sune Mølgaard
http://molgaard.org/code/linux-2.4.31-picopower.patch

Ported to 2.6.20 by Chmouel Boudjnah (http://www.chmouel.com)

Testing and confirmation that it works by Austin Acton

Cleaned up a little for inclusion in a 2.6.21-rc7 based kernel.

Added some more cleanups according to CodingStyle, as noted by
Randy Dunlap on LKML.

aa24886e37 dma_free_coherent() needs irqs enabled (sigh)
On at least ARM (and I'm told MIPS too) dma_free_coherent() has a newish
call context requirement: unlike its dma_alloc_coherent() sibling, it may
not be called with IRQs disabled.  (This was new behavior on ARM as of late
2005, caused by ARM SMP updates.) This little surprise can be annoyingly
driver-visible.

Since it looks like that restriction won't be removed, this patch changes
the definition of the API to include that requirement.  Also, to help catch
nonportable drivers, it updates the x86 and swiotlb versions to include the
relevant warnings.  (I already observed that it trips on the
bus_reset_tasklet of the new firewire_ohci driver.)

Force detect and/or enable HPET on ICH chipsets.  This patch just handles the
detection part and following patches use this information.  Adds a function to
repeat the force enabling during resume time.

Using HPET this way, instead of PIT increases the time CPUs can reside in
C-state when system is totally idle.  On my test system with Core 2 Duo,
average C-state residency goes up from ~20mS to ~80mS.

4e77ae3e10 x86: Fix irq0 / local apic timer accounting
The clock events merge introduced a change to the nmi watchdog code to
handle the not longer increasing local apic timer count in the
broadcast mode. This is fine for UP, but on SMP it pampers over a
stuck CPU which is not handling the broadcast interrupt due to the
unconditional sum up of local apic timer count and irq0 count.

To cover all cases we need to keep track on which CPU irq0 is
handled. In theory this is CPU#0 due to the explicit disabling of irq
balancing for irq0, but there are systems which ignore this on the
hardware level. The per cpu irq0 accounting allows us to remove the
irq0 to CPU0 binding as well.

Add a per cpu counter for irq0 and evaluate this instead of the global
irq0 count in the nmi watchdog code.

lack of subsystem separation!)

89039b37be x86: force timer broadcast on late AMD C1E detection
The 64bit SMP bootup is slightly different to the 32bit one. It enables
the boot CPU local APIC timer before all CPUs are brought up. Some AMD C1E
systems have the C1E feature flag only set in the secondary CPU. Due to
the early enable of the boot CPU local APIC timer the APIC timer is
registered as a fully functional device. When we detect the wreckage during
the bringup of the secondary CPU, we need to force the boot CPU into
broadcast mode. 

Check the C1E caused APIC timer disable, when the secondary APIC timer is
initialized. If the boot CPU APIC timer was registered as a functional
clock event device, then fix this up and utilize the
CLOCK_EVT_NOTIFY_BROADCAST_FORCE mechanism to force the already
registered boot CPU APIC timer into broadcast mode.

Tested by force injecting the failure mode.

835c34a168 Delete filenames in comments.
Since the x86 merge, lots of files that referenced their own filenames
are no longer correct.  Rather than keep them up to date, just delete
them, as they add no real value.

Additionally:
- fix up comment formatting in scx200_32.c
- Remove a credit from myself in setup_64.c from a time when we had no SCM
- remove longwinded history from tsc_32.c which can be figured out from
  git.

df1bdc0667 x86: fence oostores on 64-bit
movnt* instructions are not strongly ordered with respect to other stores,
so if we are to assume stores are strongly ordered in the rest of the 64
bit code, we must fence these off (see similar examples in 32 bit code).

[ The AMD memory ordering document seems to say that nontemporal stores can
  also pass earlier regular stores, so maybe we need sfences _before_
  movnt* everywhere too? ]
