Paul Burton ef1c47afc0 MIPS: Clear upper bits of FP registers on emulator writes ... The upper bits of an FP register are architecturally defined as unpredictable following an instructions which only writes the lower bits. The prior behaviour of the kernel is to leave them unmodified. This patch modifies that to clear the upper bits to zero. This is what the MSA architecture reference manual specifies should happen for its wider registers and is still permissible for scalar FP instructions given the bits unpredictability there.
