Additionally, PTEs in MIPS32R2 should have the same layout for the

I've decided to tead off that part (incomplete anyway) and move it to
a separate patch which I'll post shortly.
I'm really not sure that we need that #if defined(CONFIG_CPU_MIPS32) -- it
renders CONFIG_64BIT_PHYS_ADDR non-working on all other 32-bit CPUs for which
Kconfig entry claims that this support exists:
config 64BIT_PHYS_ADDR
bool "Support for 64-bit physical address space"
depends on (CPU_R4X00 || CPU_R5000 || CPU_RM7000 || CPU_RM9000 ||
CPU_R10000 || CPU_SB1 || CPU_MIPS32 || CPU_MIPS64) && 32BIT
At least RM7000 has the same PTE layout as MIPS32, I guess the others also
do. I suspect that the intent was to limit this option to the Alchemy CPUs
where it's *really* necessary?
WBR, Sergei
