Subject: [PATCH] powerpc: Make 256k pages depend on PPC32=n

256k pages are not tested on PPC32. On a randconfig I got the following error:

arch/powerpc/kernel/misc_32.S:1171: Error: operand out of range (0x0000000000010000 is not between 0xffffffffffff8000 and 0x0000000000007fff)

Disable 256K pages if PPC32=y
