-Subject: [PATCH] MIPS: uasm: Enable muhu opcode for MIPS R6
-
-Enable the 'muhu' instruction, complementing the existing 'mulu', needed
-to implement a MIPS32 BPF JIT.
-
-Also fix a typo in the existing definition of 'dmulu'.
-
-Signed-off-by: Tony Ambardar <Tony.Ambardar@gmail.com>
-
-This patch is a dependency for my 32-bit MIPS eBPF JIT.
