5713e60210 sh: pci: Initial PCI-Express support for SH7786 Urquell board.
This adds initial support for the PCI-Express module in the SH7786,
particularly as it relates to the urquell platform. Presently it is
only supported in root complex mode, with endpoint mode still requiring
more debugging. 29/32-bit mode and lane configurations are selectable via
board mode pins, and are otherwise fixed.

Only 4x and 1x PCI channels are presently handled, the PCI bridge still
requires additional debugging and stabilization in hardware.

e4c9dd0fba kmap_types: make most arches use generic header file
Convert most arches to use asm-generic/kmap_types.h.

Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h,
controlled by __WITH_KM_FENCE from each arch's kmap_types.h file.

Would be nice to be able to add custom KM_types per arch, but I don't yet
see a nice, clean way to do that.

Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and
68k(tonyb).

Note: avr32 should be able to remove KM_PTE2 (since it's not used) and
then just use the generic kmap_types.h file.  Get avr32 maintainer
approval.

bb1f17b037 mm: consolidate init_mm definition
* create mm/init-mm.c, move init_mm there
* remove INIT_MM, initialize init_mm with C99 initializer
* unexport init_mm on all arches:

  init_mm is already unexported on x86.

  One strange place is some OMAP driver (drivers/video/omap/) which
  won't build modular, but it's already wants get_vm_area() export.
  Somebody should look there.

724cfb9440 sh: smsc911x support for the rsk7203 board
This patch adds support for the LAN9118 ethernet on rsk7203.

The LAN9118 controller is hooked up using a 16-bit data bus,
but the rsk7203 board does not swap the byte lanes as needed
between the sh7203 processor and the the ethernet controller.

In the processor the CS memory window is configured in 16-bit
mode but the smsc911x driver is told to do 32-bit accesses to
improve performance. The SMSC911X_SWAP_FIFO flag is used
to tell the driver to do software byte swapping of fifo data.

0c50f6f383 sh: Make the atomic functions safe for irqsoff tracing
The irqsoff tracer uses the atomic_* functions internally, but the
implementations of those functions in arch/sh/include/asm/atomic-irq.h
disable irqs to achieve atomicity. A continuous loop ensues where we
disable interrupts, trace the interrupt disabling, call atomic_*
functions, disable interrupts, trace the interrupt disabling, etc..

The simplest solution to all this is to just convert uses of
local_irq_save()/local_irq_restore() the raw_* equivalents because the
raw_* equivalents don't call trace_hardirqs_on()/trace_hardirqs_off().
