Hi,

Could you please remove the line "#define cpu_hwrena_impl_bits    0xc0000000" in arch/mips/include/asm/mach-loongson64/cpu-feature-overrides.h and try again?Thanks.

Hi,

qemu fails to boot in -next for machine fulong2e with configuration
fuloong2e_defconfig. Bisect points to commit 'MIPS: Loongson: Add
Loongson-3A R2 basic support'. qemu hangs in boot, after displaying 
"Inode-cache hash table entries: 16384 (order: 3, 131072 bytes)".

Bisect log is attached.
