Patch 1/2
[SK98LIN]: Added Support for Belkin adapter
[SK98LIN]: Don't handle Yukon2 cards at the moment

The pcnet32 driver uses the incorrect length (of zero) in
pci_[un]map_single for receive buffers.  This is seen with SLAB_DEBUG
enabled.

Tested in IA32 system.  If this patch is not applied after my previous
one hunks #1, #3, and #5 will have an offset of -2 lines.

Jean discovered problem with my hp100 PCI changes.
This should fix the problem... The multi-bus probe logic error handling was
botched.

He validated it; so please apply

Here is the first of several individual patches to 2.6.3 for the pcnet32
driver.

The driver did not properly serialize accesses to chip registers, resulting
in reading/writing the wrong register.  This patch eliminates this problem
and gets rid of the cause of the symptom of 'bus master arbitration failure'.

It was easier to use generic_mii_ioctl than modify the current pcnet32_ioctl
routine with the necessary locks.  This has been re-tested on an IA32 system.

P4 support was previously ifdefed out for x86-64, remove that.

Enable the Intel AGP driver for x86-64 too.

The microcode driver needs to support 64bit physical addresses too.

This has all the x86-64 specific changes for Intel Prescott/Nocona
support.

It requires a few minor changes outside arch/x86_64, which I am sending
separately.

This patch is needed to boot an 64bit kernel on a 64-bit capable
Prescott machine.

The ugliest part is probably the swiotlb code.  In fact the code for
that is not even included, but just reused from IA64.  swiotlb
implements the PCI DMA API using bounce buffering.  I don't like this at
all, but there was no other way to support non DAC capable hardware
(like IDE or USB) on machines with >3GB.  Please redirect all flames for
that to the Intel chipset designers.

ChangeLog:
- Add Kconfig options for PSC
- Add support to reuse microcode driver from i386 (Suresh B Siddha)
- Try to optimize for the selected CPU
- Fix early CPUID check for Intel CPUs (Suresh B Siddha)
- Fix GDT to use the configured cache line size for padding
- Support monitor/mwait idle loop
- Support HyperThreading
- Support Intel CPUID flags
- Remove all 3dnow prefetches
- Add alternative() for the prefetchw prefetch inline.
- Include P4 driver in oprofile
- Support Intel NOPs in alternative

From: Neal Stephenson <neal@bakerst.org>

In 2.6.2, I noticed that my modprobe.conf line for tuner "options tuner
type=2" no longer worked.  It even failed with insmod "insmod tuner.ko
type=2".  dmesg reported

vmunix: tuner: chip found @ 0xc0
vmunix: tuner: type set to 19 (Temic PAL* auto (4006 FN5))
vmunix: tuner: type forced to 19 (Temic PAL* auto (4006 FN5)) [insmod]

I noticed that the a line had been removed from 2.6.1 and when it is added
everything works again.

Disable the RADEON_PARAM_SAREA_HANDLE ioctl on 64-bit architectures,
since it is only used on some embedded platforms, and it isn't 64-bit
safe.

drivers that need it. 

This allows us to have I2C as a module iff the FB driver
that needs it is a module.

This allows us to do something like

	config FB_RADEON
		select I2C_ALGOBIT if FB_RADEON_I2C

where FB_RADEON_I2C itself depends on FB_RADEON without getting a bogus
warning about recursive dependencies.

This matters because the select takes the default minimum dependancy
from the parent menu, so we want to do this under FB_RADEON rather than
under FB_RADEON_I2C (so that the I2C_ALGOBIT config depends properly
on the state of FB_RADEON)

	We used to have sync_blockdev() on each normal (== non-raw)
blkdev_put() + kill_bdev() on the final blkdev_put().  That worked
fine until we'd moved sync_blockdev() to the final blkdev_put().

	Now we have a nasty scenario:

open block device
open raw device
write on block device	# data ends up in cache
close block device	# no sync here, we still have the sucker opened
close raw device	# no sync here either
			# ... and cache is killed by kill_bdev()

	IOW, if we postpone sync to final close, we must do it regardless of
kind of close.  Otherwise we are in for data corruption and yes, it is easy
to trigger.  Fix is obvious...

1) First action must be to set MAC_EVENT to zero.
2) Do not forget to clear MI_COMPLETION/LNKSTATE_CHANGED
   status bits in MAC_STATUS register.

This fixes the bug wherein the link does not come up at all
at the first ifup done after tg3 module load.

kunmap_atomic() takes a kernel-virtual address, not a pageframe address.

(Very common problem.  We really should make the atomic kmap functions
type-safe).

There's a fencepost error in the GART IOMMU handling on x86_64
in the unmap path.  When testing to see if the bus address is
within the IOMMU window and needs to be unmapped, the start of
the first page *beyond* the window also passes the test.  This
can cause the first doubleword of the next page beyond the gatt
table to be smashed to zero, with unpredictable results depending
on what that page is used for.

The attached trivial patch should fix the "i1-dig" build failure reported
on this page:

	http://www.gelato.unsw.edu.au/kerncomp/

and should make it easier to build a properly configured ia64 kernel.

This is a cleaned-up version of a mremap() fix for "move_one_page()"
by Rajesh Venkatasubramanian <vrajesh@umich.edu>. We could use a NULL
"src" pointer.

Because while we do hold the MM semaphore over the whole sequence, the
destination page table allocation will possibly drop the page table
spinlock.  That in turn can cause a clean source page to be stolen by
page reclaim, causing the source-side "get_one_pte_map_nested()" to
return NULL the second time around even if it didn't on the first case.

So we just check "src" again, and get rid of the bogus TLB invalidate
while we're at it.

My "__ide_dma_off()" cleanup uncovered some code that shouldn't be compiled
when CONFIG_BLK_DEV_IDEDMA=n.  Fix it and kill a warning in setup-pci.c.

Noticed by Martin Diehl <lists@mdiehl.de>.
