Log Message:
Change MIPS_CURLWP from s7 to t8.  In a MALTA64 kernel, s6 is used 9155 times
which means the compiler could really use s7 is was free to do so.  The least
used temporary was t8 (288 times).  Once the kernel was switched to use t8 for
MIPS_CURLWP, s7 was used 7524 times.

Additionally a MALTA32 kernel shrunk by 6205 instructions (24820 bytes) or
about 1% of its text size.

[For some reason, pre-change t1 was never used and post change t2 was never
used.  Not sure why.]
