[Qemu-devel] [PATCH 3/3] linux-user: MIPS set cpu to r6 CPU if binary is R6 |
Date: |

From: YunQiang Su <address@hidden>
So here we need to detect the version of binaries and set
cpu_model for it.
[lv: original patch modified to move code into get_cpu_model()]
Signed-off-by: Laurent Vivier <address@hidden>

Notes:
YunQiang Su, please add your Signed-off-by that was
missing in your original patch.
