[Qemu-devel] [PATCH] mips: Correct the handling of writes to CP0.Status for MIPSr6

2014-11-10 Thread Maciej W. Rozycki
Correct these issues with the handling of CP0.Status for MIPSr6: * only ignore the bit pattern of 0b11 on writes to CP0.Status.KSU, that is for processors that do implement Supervisor Mode, let the bit pattern be written to CP0.Status.UM:R0 freely (of course the value written to read-only
