It is marked as accepted, so it should be in Ralf's queue.
Thanks,

Did you ever send a patch to fix this problem ? It is still broken in
next-20160512.

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.
That fixes the problem.
Does this need to be addressed in qemu or in the Linux kernel ?
Thanks,

Subject: next: fuloong2e qemu boot failure due to 'MIPS: Loongson:
AddLoongson-3A R2 basic support'
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.
