cd03adb081 [ARM SMP] Add support for shared memory attribute
We need to set the shared memory attribute in the page tables
on SMP systems to allow the cache coherency to operate.

67c5587ad4 [ARM] 3024/1: Add cpu_v6_proc_fin
Patch from Tony Lindgren

Machine restart calls cpu_proc_fin() to clean and disable
cache, and turn off interrupts. This patch adds proper
cpu_v6_proc_fin.

02b7dd1244 [ARM] 2926/1: .proc.info - postfix section with .init for make buildcheck
Patch from Ben Dooks

The `make buildcheck` is erroneously reporting that the .proc.info
list is referencing items in the .init section as it is not itself
postfixed with .init

6626a7076d [ARM] Control v6 'global' bit via Linux PTE entries
Unfortunately, we can't use the "user" bit in the page tables to
control whether a page table entry is "global" or "asid" specific,
since the vector page is mapped as "user" accessible but is not
process specific.

Therefore, give direct control of the ARMv6 "nG" (not global)
bit to the mm layers.

d1d890edac [PATCH] ARM: 2789/1: Enable access to both CP10 and CP11 on ARMv6
Patch from Catalin Marinas

The VFP instructions trigger undefined exceptions because the access to
CP11 is disabled (only CP10 is currently enabled by the kernel). The patch
fixes this problem.

79042f087b [PATCH] ARM: 2698/1: Enable kernel r/w access to user pages on ARMv6
Patch from Catalin Marinas

cpu_v6_set_pte() sets the kernel access rights to r/o for user
pages (L_PTE_USER) when neither L_PTE_WRITE nor L_PTE_DIRTY are
set. This causes a kernel data abort when writing the TLS value
in the 0xffff0000 page. This patch enables the kernel r/w access.

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!
