A forward port of changes from Paul Mackerras.

This exposes warnings in todc_time.c for everyone, and then
fixes them.

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...

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>.

Bug discovered by Olaf Kirch.

The platinum framebuffer is repeated twice. Removed one of them.

There's an incorrect redefinition extern/static in prep_pci.

Just remove it.

Hello.  The following patch is all that is required to get current 2.6 to
compile and work on MPC82xx platforms.

From: Tom Rini <trini@kernel.crashing.org>

Replace MSR_, which is gone now, with the value it used to be.  Required to
get the MPC82xx platforms compiling again.

This fixes the build of "allyesconfig", old and new radeonfb's would
collide on some symbols.

It results in serial console getting initialised really late and the
suggested workaround is broken according to Keith.

The rtasd kernel thread would exit before daemoniz'ing itself if
RTAS wasn't present (or if allocation of the buffer failed), thus
leaving a zombie. This patch fixes it (and remove #if 0'ed code)

Move ide-dma.c:__ide_dma_off() outside of #ifdef CONFIG_BLK_DEV_IDEDMA_PCI,
so it can be used for all DMA capable hosts.  Remove ide_hwif_t->ide_dma_off.

->ide_dma_count() was introduced in kernel 2.5.35 and was meant to add support
for host FIFO counters (for VDMA), but is only a wrapper for ->ide_dma_begin()
(even for siimage.c b/c SIIMAGE_VIRTUAL_DMAPIO is undefined).

Moreover it should be possible to add VDMA code directly to ->ide_dma_begin().

Use __ide_dma_{good,bad}_drive() directly and remove these wrappers.

I see only pros of removing OnStream support:
 - SCSI osst.c driver is actively maintained by Willem Riede <wrlk@riede.org>
 - there is no functionality loss (OnStream IDE drives don't support DSC)
 - ide-tape.c driver is too ugly & complicated even without OnStream support
 - long term benefits (2.7.x plans on unifying storage drivers)
