Patch from Nicolas Pitre
Although ARM is still using 32-bit pointers, version 5 and later
versions of the ARM architecture introduced the ldrd and strd
instructions to move 64-bit data which must be 64-bit aligned in memory,
and the EABI includes new constraints on structure data alignment to
allow for the compiler to use those instructions. This means that any
slab allocation must start on a 64-bit boundary which is not equivalent
to BYTES_PER_WORD, especially on those architecture versions that
implements the ldrd/strd instructions.
Overriding the default alignment disables some slab debug features. If
those debug features are really needed then the kernel will have to be
compiled for version 4 of the ARM architecture.

Now that no code uses it anymore, mark it deprecated and remove all

Patch from Lennert Buytenhek
For the ixp2000 netdev driver, we need to map in a chunk of SRAM (to
store the transmit and receive descriptors) and the scratch get/put
area (so that we can use the scratchpad rings in the cpu for managing
the descriptors.) These are the final two mappings needed for the
netdev driver and the last missing piece for the driver in mainline
to work.

The comments in ieee80211.h claim that one doesn't need to set the len
parameter of the stats struct. But if one doesn't, the management frames
are read far over the memory they actually occupy causing badness.

We can now have the gianfar mii platform device have a proper resource for the
IO memory region for its registers. Previously we passed this information
that the platform_data structure because we couldn't handle overlapping memory
regions for platform devices.

There's a problem with the REQ_BLOCK_PC handling as well (bad ->data_len
handling) where it could actually complete a request ahead of time. I
suggest we just back this out for now, I will resubmit it later when I'm
fully confident in it.

asm-m68k/hardirq.h to asm-m68k/irq.h; needed since NR_IRQS is not necessary
know at the points of inclusion of asm/hardirq.h due to the rather ugly header
dependencies on m68k. Fix is by far simpler than trying to massage those
