4.20-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 17f6c83fb5ebf7db4fcc94a5be4c22d5a7bfe428 ]
For micro-mips, srlv inside POOL32A encoding space should use 0x50 sub-opcode, NOT 0x90.
Some early version ISA doc describes the encoding as 0x90 for both srlv and srav, this looks to me was a typo. I checked Binutils libopcode implementation which is using 0x50 for srlv and 0x90 for srav.
v1->v2: - Keep mm_srlv32_op sorted by value.
