Subject: [PATCH] MIPS: select CPU_MIPS64 for remaining MIPS64 CPUs
The CPU_MIPS64 and CPU_MIPS32 variables are supposed to be able to
distinguish broadly between 64-bit and 32-bit MIPS CPUs. However, they
weren't selected by the specialty CPUs, Octeon and Loongson, which meant
it was possible to hit a weird state of:
MIPS=y, CONFIG_64BIT=y, CPU_MIPS64=n
This commit rectifies the issue by having CPU_MIPS64 be selected when
the missing Octeon or Loongson models are selected.
