This series provides a machine check handler to catch out of bounds memory accesses in early boot before the MMU is enabled. Since v1: - 64e compile fix Nicholas Piggin (5): powerpc/64s/interrupt: move early boot ILE fixup into a macro powerpc/64s: early boot machine check handler powerpc/64: avoid using r13 in relocate powerpc/64: don't set boot CPU's r13 to paca until the structure is set up powerpc/64s/interrupt: halt early boot interrupts if paca is not set up arch/powerpc/include/asm/asm-prototypes.h | 1 + arch/powerpc/kernel/exceptions-64s.S | 117 +++++++++++++--------- arch/powerpc/kernel/head_64.S | 3 + arch/powerpc/kernel/reloc_64.S | 14 +-- arch/powerpc/kernel/setup_64.c | 33 ++++-- arch/powerpc/kernel/traps.c | 14 +++ 6 files changed, 120 insertions(+), 62 deletions(-)
