Dmitri Vorobiev 17f61e61b4 [MIPS] Make two functions static
The following routines

uasm_rel_highest()
uasm_rel_higher()

are needlessly defined global. This patch makes them static.

Compile-tested using a customized config for the Malta board. Booting
the same board up to the shell prompt was also successful with this
patch applied.

Spotted by sparse.

Thiemo Seufer fb2a27e743 [MIPS] Reimplement clear_page/copy_page
Fold the SB-1 specific implementation of clear_page/copy_page in the
generic version, and rewrite that one in tlbex style. The immediate
benefits:
  - It converts the compile-time workaround for SB-1 pass 1 prefetches
    to a more efficient run-time check.
  - It allows adjustment of loop unfolling, which helps to reduce the
    number of redundant cdex cache ops.
  - It fixes some esoteric cornercases (the cache line length calculations
    can go wrong, and support for 64k pages without prefetch instructions
    will overflow the addiu immediate).
  - Somewhat better guesses of "good" prefetch values.

Thiemo Seufer e30ec4525d [MIPS] Split the micro-assembler from tlbex.c.
This patch moves the micro-assembler in a separate implementation, as
it is useful for further run-time optimizations. The only change in
behaviour is cutting down printk noise at kernel startup time.

Checkpatch complains about macro parameters which aren't protected by
parentheses. I believe this is a flaw in checkpatch, the paste operator
used in those macros won't work with parenthesised parameters.
