[Qemu-devel] [PATCH] linux-user: Use the 5KEf processor for 64-bit emulation

2014-11-20 Thread Maciej W. Rozycki
Replace the 20Kc original MIPS64 ISA processor used for 64-bit user emulation with the 5KEf processor that implements the MIPS64r2 ISA, complementing the choice of the 24Kf processor for 32-bit emulation. Signed-off-by: Maciej W. Rozycki --- Hi, For user emulation mode I think we want to defaul
