Atsushi Nemoto c226f2601f [MIPS] TX49 MFC0 bug workaround
If mfc0 $12 follows store and the mfc0 is last instruction of a
page and fetching the next instruction causes TLB miss, the result
of the mfc0 might wrongly contain EXL bit.
    
ERT-TX49H2-027, ERT-TX49H3-012, ERT-TX49HL3-006, ERT-TX49H4-008
    
Workaround: mask EXL bit of the result or place a nop before mfc0.  It
doesn't harm to always clear those bits, so we change the code to do so.

Ralf Baechle 2e66fe24d6 [MIPS] local_irq_restore wasn't safe to be used in other macros mode.
It always left the assembler in reorder mode possibly causing disaster.

Maxime Bizon 15265251c5 MIPS: R2: Fix local_irq_save()
local_irq_restore uses di which saves the whole status content, not
just the IE bit resulting in  local_irq_restore() to fail.  This only
happens if both CONFIG_CPU_MIPSR2 and CONFIG_IRQ_CPU are enabled.

Linus Torvalds 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!
