Booting a POWER9 PowerNV system generates a few messages below with "____ptrval____" due to the pointers printed without a specifier extension (i.e unadorned %p) are hashed to prevent leaking information about the kernel memory layout. radix-mmu: Initializing Radix MMU radix-mmu: Partition table (____ptrval____) radix-mmu: Mapped 0x0000000000000000-0x0000000040000000 with 1.00 GiB pages (exec) radix-mmu: Mapped 0x0000000040000000-0x0000002000000000 with 1.00 GiB pages radix-mmu: Mapped 0x0000200000000000-0x0000202000000000 with 1.00 GiB pages radix-mmu: Process table (____ptrval____) and radix root for kernel: (____ptrval____) Signed-off-by: Qian Cai <cai@lca.pw> --- arch/powerpc/mm/book3s64/radix_pgtable.c | 2 -- 1 file changed, 2 deletions(-)
