MIPS: Adjust set_pte() SMP fix to handle R10000_LLSC_WAR

Browse source

commit 128639395b upstream.

Update the recent changes to set_pte() that were added in 46011e6ea3
to handle R10000_LLSC_WAR, and format the assembly to match other areas
of the MIPS tree using the same WAR.

This also incorporates a patch recently sent in my Markos Chandras,
"Remove local LL/SC preprocessor variants", so that patch doesn't need
to be applied if this one is accepted.

[bwh: Backported to 3.2:
 - Use {LL,SC}_INSN not __{LL,SC}
 - Use literal arch=r4000 instead of MIPS_ISA_ARCH_LEVEL since R6 is not
   supported]
