Paul Burton f23ce3883a MIPS: assume at as source/dest of MSA copy/insert instructions ... Assuming at ($1) as the source or destination register of copy or insert instructions: - Simplifies the macros providing those instructions for toolchains without MSA support. - Avoids an unnecessary move instruction when at is used as the source or destination register anyway. - Is sufficient for the uses to be introduced in the kernel by a subsequent patch. Note that due to a patch ordering snafu on my part this also fixes the currently broken build with MSA support enabled. The build has been broken since commit c9017757c5 "MIPS: init upper 64b of vector registers when MSA is first used", which this patch should have preceeded.
