d53ace7005 [ARM] Allow un-muxed syscalls to be available for everyone
It's been a while since the un-muxed socket and ipc syscalls were
introduced, so make the unistd.h number definitions visible for
non-EABI as well as EABI.

c471307437 [ARM] 3388/1: ixp23xx: add core ixp23xx support
Patch from Lennert Buytenhek

This patch adds support for the Intel ixp23xx series of CPUs.  The
ixp23xx is an XSC3 based CPU with 512K of L2 cache, a 64bit 66MHz PCI
interface, two DDR RAM interfaces, QDR RAM interfaces, two gigabit
MACs, two 10/100 MACs, expansion bus, four microengines, a Media and
Switch Fabric unit almost identical to the one on the ixp2400, two
xscale (8250ish) UARTs and a bunch of other stuff.

This patch adds the core ixp23xx support code, and support for the
ADI Engineering Roadrunner, Intel IXDP2351, and IP Fabrics Double
Espresso platforms.

23bdf86aa0 [ARM] 3377/2: add support for intel xsc3 core
Patch from Lennert Buytenhek

This patch adds support for the new XScale v3 core.  This is an
ARMv5 ISA core with the following additions:

- L2 cache
- I/O coherency support (on select chipsets)
- Low-Locality Reference cache attributes (replaces mini-cache)
- Supersections (v6 compatible)
- 36-bit addressing (v6 compatible)
- Single instruction cache line clean/invalidate
- LRU cache replacement (vs round-robin)

I attempted to merge the XSC3 support into proc-xscale.S, but XSC3
cores have separate errata and have to handle things like L2, so it
is simpler to keep it separate.

L2 cache support is currently a build option because the L2 enable
bit must be set before we enable the MMU and there is no easy way to
capture command line parameters at this point.

There are still optimizations that can be done such as using LLR for
copypage (in theory using the exisiting mini-cache code) but those
can be addressed down the road.

c9b4470e2d [ARM] 3414/1: ep93xx: reset ethernet controller before uncompressing
Patch from Lennert Buytenhek

The Redboot version that cirrus supplies for the cirrus ep93xx doesn't
turn off DMA from the ethernet MAC before jumping to linux, which means
that we might end up with bits of RX status and packet data scribbled
over the uncompressed kernel image.

Work around this by resetting the ethernet MAC before we uncompress.

We don't usually work around bootloader bugs, but considering that the
large majority of ep93xx boards out there have this problem, I figured
this it was justified in this case.

Quoting RMK:

|pte_write() just says that the page _may_ be writable. It doesn't say
|that the MMU is programmed to allow writes. If pte_dirty() doesn't
|return true, that means that the page is _not_ writable from userspace.
|If you write to it from kernel mode (without using put_user) you'll
|bypass the MMU read-only protection and may end up writing to a page
|owned by two separate processes.

40caa88465 [PATCH] x86_64: Eliminate register_die_notifier symbol exported
register_die_notifier is exported twice, once in traps.c and once in
x8664_ksyms.c.  This results in a warning on build.

9c01dda02f [PATCH] x86_64: Search K8 devices on more devices.
arch/x86_64/kernel/aperture.c: The search for the AGP bridge has been
extended to search for all the 256 buses instead of the first 32. This
is required since on a some systems, the bridge may be located on a bus
much farther than the first 32. By searching all 256 buses, we guarantee
that the search succeeds on such systems.

arch/x86_64/kernel/pci-gart.c: The search for the Northbridge is not
limited to just bus 0 anymore. This is required because on certain
systems, we may not find one on bus 0.

5d05f4de41 [PATCH] x86_64: Make GART_IOMMU kconfig help text more specific (trivial)
Have the GART_IOMMU help text specify that this is the hardware IOMMU in
amd64 processors.  This will be significant if/when other IOMMUs are
added to the x86-64 architecture. :-)

Also, note that the previous help text stated that IOMMU was needed for
>3GB memory instead of >4GB.  This is fixed in the newer version.
