Jayachandran, could you please confirm/deny the following:

Netlogic XLR is a MIPS64 R1 system.

You are running a 32-bit kernel.

You are using 64-bit physical addresses.

You are not enabling RI/XI.

The commit that caused the regression was "[PATCH 1/4] MIPS: Replace
_PAGE_READ with _PAGE_NO_READ" (not 2/4, 3/4, or 4/4).

Do you have a log showing the failure, or any other details of what happened?

Thanks.
