Re: [PATCH 1/6] MIPS: Loongson64: Do not write the read only field LPA of CP0_CONFIG3

The field LPA of CP0_CONFIG3 register is read only for Loongson64, so the
write operations are meaningless, remove them.

Hi Tiezhu,

AFAIK it's not read only on 3A1000.
Have you check with hardware guys?

Thanks.
