This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
and it fixes the build error in the arch/x86/kernel/microcode_core.c
file, that the merge did not catch.
The microcode_core.c patch was provided by Stephen Rothwell
<sfr@canb.auug.org.au> who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.

Add support for the "msi-address-64" property to the fsl_pci driver.

Systems which use the fsl_pq_mdio driver need to specify an
address for TBI PHY transactions such that the address does
not conflict with any PHYs on the bus (all transactions to
that address are directed to the onboard TBI PHY). The driver
used to scan for a free address if no address was specified,
however this ran into issues when the PHY Lib was fixed so
that all MDIO transactions were protected by a mutex. As it
is, the code was meant to serve as a transitional tool until
the device trees were all updated to specify the TBI address.
The best fix for the mutex issue was to remove the scanning code,
but it turns out some of the newer SoCs have started to omit
the tbi-phy node when SGMII is not being used. As such, these
devices will now fail unless we add a tbi-phy node to the first
mdio controller.

There is an issue on FSL-BookE 64-bit devices (P5020) in which PCIe
devices that are capable of doing 64-bit DMAs (like an Intel e1000) do
not function and crash the kernel if we have >4G of memory in the system.
The reason is that the existing code only sets up one inbound window for
access to system memory across PCIe. That window is limited to a 32-bit
address space. So on systems we'll end up utilizing SWIOTLB for dma
mappings. However SWIOTLB dma ops implement dma_alloc_coherent() as
dma_direct_alloc_coherent(). Thus we can end up with dma addresses that
are not accessible because of the inbound window limitation.
We could possibly set the SWIOTLB alloc_coherent op to
swiotlb_alloc_coherent() however that does not address the issue since
the swiotlb_alloc_coherent() will behave almost identical to
dma_direct_alloc_coherent() since the devices coherent_dma_mask will be
greater than any address allocated by swiotlb_alloc_coherent() and thus
we'll never bounce buffer it into a range that would be dma-able.
The easiest and best solution is to just make it so that a 64-bit
capable device is able to DMA to any internal system address.
We accomplish this by opening up a second inbound window that maps all
of memory above the internal SoC address width so we can set it up to
access all of the internal SoC address space if needed.
We than fixup the dma_ops and dma_offset for PCIe devices with a dma
mask greater than the maximum internal SoC address.

LOCK_PREFIX
cmpxchg8b (%ebp)
jne 1b / jumps to beginning of LOCK_PREFIX !
A possible fix is to use a magic label "672" in LOCK_PREFIX asm
definition, similar to the "671" one we defined in
LOCK_PREFIX_HERE.

Just like the per-CPU ones they had several
problems/shortcomings:
Only the first memory operand was mentioned in the asm()
operands, and the 2x64-bit version didn't have a memory clobber
while the 2x32-bit one did. The former allowed the compiler to
not recognize the need to re-load the data in case it had it
cached in some register, while the latter was overly
destructive.
The types of the local copies of the old and new values were
incorrect (the types of the pointed-to variables should be used
here, to make sure the respective old/new variable types are
compatible).
The __dummy/__junk variables were pointless, given that local
copies of the inputs already existed (and can hence be used for
discarded outputs).
The 32-bit variant of cmpxchg_double_local() referenced
cmpxchg16b_local().
At once also:
- change the return value type to what it really is: 'bool'
- unify 32- and 64-bit variants
- abstract out the common part of the 'normal' and 'local' variants

both callers of device_get_devnode() are only interested in lower 16bits
and nobody tries to return anything wider than 16bit anyway.

Move invalidate_bdev, block_sync_page into fs/block_dev.c. Export
kill_bdev as well, so brd doesn't have to open code it. Reduce
buffer_head.h requirement accordingly.
Removed a rather large comment from invalidate_bdev, as it looked a bit
obsolete to bother moving. The small comment replacing it says enough.
