MIPS: Use copy_s.fmt rather than copy_u.fmt

Browse source

commit 8a3c8b48ac upstream.

In revision 1.12 of the MSA specification, the copy_u.w instruction has
been removed for MIPS32 & the copy_u.d instruction has been removed for
MIPS64. Newer toolchains (eg. Codescape SDK essentials 2015.10) will
complain about this like so:

arch/mips/kernel/r4k_fpu.S:290: Error: opcode not supported on this
processor: mips32r2 (mips32r2) `copy_u.w $1,$w26[3]'

Since we always copy to the width of a GPR, simply use copy_s instead of
copy_u to fix this.
