[PATCH] gianfar mii: Use proper resource for MII memory region
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.

[PATCH] CONFIG_AIRO needs CONFIG_CRYPTO
airo.c currently has MICSUPPORT enabled, which requires CONFIG_CRYPTO. A
user reported a build failure which is due to the lack of a Kconfig
dependency. See http://bugs.debian.org/344205.
This patch makes Kconfig enforce this dependency.

[PATCH] corruption during e100 MDI register access
We have identified two related bugs in the e100 driver.
Both bugs are related to manipulation of the MDI control register.
The first problem is that the Ready bit is being ignored when writing to
the Control register; we noticed this because the Linux bonding driver
would occasionally come to the spurious conclusion that the link was down
when querying Link State. It turned out that by failing to wait for a
previous command to complete it was selecting what was essentially a random
register in the MDI register set. When we added code that waits for the
Ready bit (as shown in the patch file below) all such problems ceased.
The second problem is that, although access to the MDI registers involves
multiple steps which must not be intermixed, nothing was defending against
two or more threads attempting simultaneous access. The most obvious
situation where such interference could occur involves the watchdog versus
ioctl paths, but there are probably others, so we recommend the locking
shown in our patch file.

[PATCH] Revert ide softirq handling
There's a problem with the REQ_BLOCK_PC handling as well (bad ->data_len

suggest we just back this out for now, I will resubmit it later when I'm
fully confident in it.

[ARM] Allow r2 to be passed through the decompressor to the kernel
This is part of a patch from Marc Singer to allow r2 to be
passed to the kernel. Marc's original comments follow:
This revised R2 (atags pointer) patch incorporates comments from Nico
Pitre and Ben Dooks. It modifies the head.S files such that the R2
value set by the bootloader is conveyed to the kernel startup code.
The kernel head.S heuristically validates the pointer. It will set R2
to zero if it believes the pointer is invalid. Presently, it requires
that the ATAGS list reside in the first 16KiB of physical RAM.
Relaxing this contraint may be both desirable as well as tricky.

[PATCH] m68k: fix PIO case in esp
we always set ->SCp.ptr to physical address of buffer; for DMA that's
just what we need, but we end up using it as virtual address in PIO
case of esp_do_data(), with obvious breakage as soon as memory mapping
becomes non-trivial. The fix is obvious.

oktagon_esp is described as modular. However, drivers/scsi/Makefile doesn't

that not only wouldn't work (oktagon_io.o doesn't have the right parts for
that), it actually doesn't even build since kbuild doesn't believe in
single-object modules built from .S. Turned into proper multi-object
