3a1e501511 [PATCH] ARM: 2655/1: ARM1136 SWP instruction abort handler fix
Patch from George G. Davis

As noted in http://www.arm.com/linux/patch-2.6.9-arm1.gz, the "Faulty SWP instruction on 1136 doesn't set bit 11 in DFSR." So the v6_early_abort handler does not report the correct rd/wr direction for the SWP instruction which may result in SEGVS or hangs. In order to work around this problem, this patch merely updates the fix contained in the ARM Ltd. patch to use the macroised abort handler fixups.

458a83fa43 [PATCH] ARM: 2659/1: do not assign PCI I/O address zero on IXP2000
Patch from Lennert Buytenhek

Assigning the address zero to a PCI device BAR causes some part of the
PCI subsystem to believe that resource allocation for that BAR failed
due to resource conflicts, which will make attempts to enable the
device fail.  Work around this by assigning I/O addresses starting
from 00010000.
While we're at it, make the PCI I/O resource end at 0001ffff, since we
only have 64k of outbound I/O window on the IXP2000, and we don't do
bank switching.

ae36bf5861 [PATCH] ARM: 2658/1: start ixp2000 pci memory resource at 0xe0000000
Patch from Lennert Buytenhek

On the IXDP2800, the bootloader does an awful job of configuring
the PCI bus, so we make linux reconfigure everything.  Having a 1:1
pci:phys address mapping generally simplifies everything, so try to
allocate PCI addresses from the [e0000000..ffffffff] range, which is
the physical address range of the outbound PCI window on the IXP2000.
This does not affect any of the other IXP2000 platforms since they
all use their bootloader's PCI resource assignment.

Oddly, max_low_pfn/max_pfn end up being the number of pages in the system,
rather than the maximum PFN on ARM.  This doesn't seem to cause any problems,
so just add a note about it.

2d137c24e9 [PATCH] arm: fix SIGBUS handling
)


From: Russell King <rmk+lkml@arm.linux.org.uk>

ARM wasn't raising a SIGBUS with a siginfo structure.  Fix
__do_user_fault() to allow us to use it for SIGBUS conditions, and arrange
for the sigbus path to use this.

We need to prevent the siginfo code being called if we do not have a user
space context to call it, so consolidate the "user_mode()" tests.

Thanks to Ian Campbell who spotted this oversight.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
