aa32374aaa [MIPS] SB1: Only pass1 FPUs are broken beyond recovery. 
The wrong revision number in the check was forcing a fallback to FPU
emulation for all SB1 cores in 2.6.

c620953c32 [MIPS] Fix detection and handling of the 74K processor. 
Nothing exciting; Linux just didn't know it yet so this is most adding
a value to a case statement.

8b36612a23 [MIPS] R10000 and R12000 need to set MIPS_CPU_4K_CACHE ... 
... because they have R4000-style caches.

b382fe8483 No point in checking cpu_has_tlb before we've computed the CPU options. 
So for now we just unconditionally set the option - Linux wouldn't
work without a TLB anyway.
    
Setting MIPS_CPU_4KTLB was missing for Alchemy and Sandcraft, add that
back.

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!
