[PATCH] powerpc/mm: Fix printing of process table address

[Balbir Singh]

New changes to %p cause the information printed at boot
about radix-mmu partition and process table opaque, if
we really want to protect those values, we should make
dmesg more secure using CONFIG_SECURITY_DMESG_RESTRICT

Before the patches:

radix-mmu: Partition table         (ptrval)
radix-mmu: Process table         (ptrval) and radix root for kernel:         (ptrval)

After the patches

radix-mmu: Partition table c0000000ffff0000
radix-mmu: Process table c0000000fe000000 and radix root for kernel: c0000000015a0000
