Paul Burton 6f0aba63bf MIPS: Skip odd double FP registers when copying FP32 sigcontext 
When a task uses 32 bit floating point, the odd indexed 32b register
values are stored in bits 63:32 of the preceding even indexed 64b
FP register field in saved context. Thus there is no point in
preserving the odd indexed 64b register fields since they hold no
valid context. This patch will cause them to be skipped, as is
already done in arch/mips/kernel/signal32.c.

[ralf@linux-mips.org: Fixed reject.]
