4dc7a0bbeb [PATCH] sched: add cacheflush() asm
Add per-arch sched_cacheflush() which is a write-back cacheflush used by
the migration-cost calibration code at bootup time.

f99d3023f3 Sprinkle a few more .set mipsX over xchg to make sure we dont' end up with
64-bit instructions on 32-bit processors, they tend to be unhappy about
that kind of food ;-)

fabffc13ed Remove workaround for binutils 2.15 assembler bug; this version is not
suitable to reliably build kernels anymore anyway and 2.16 has this
fixed.

a little polishing.

c4559f67b7 Always use ".set mips3" rather than select between "mips2" or "mips3"
for assembling ll/sc sequences to avoid problems with 64-bit
configurations.

aac8aa7717 Enable a suitable ISA for the assembler around ll/sc so that code
builds even for processors that don't support the instructions.
Plus minor formatting fixes.

4866cde064 [PATCH] sched: cleanup context switch locking
Instead of requiring architecture code to interact with the scheduler's
locking implementation, provide a couple of defines that can be used by the
architecture to request runqueue unlocked context switches, and ask for
interrupts to be enabled over the context switch.

Also replaces the "switch_lock" used by these architectures with an oncpu
flag (note, not a potentially slow bitflag).  This eliminates one bus
locked memory operation when context switching, and simplifies the
task_running function.

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!
