The fourth patch hooks\nup the pfn for instruction UE errors (ierror).\n\nThe fifth patch hooks up memory_failure to the MCE patch.\n\nTODO:\nLog the address in NVRAM, so that we can recover from\nbad pages at boot and keep the blacklist persistent.\n\nChangelog v2:\n\t- Remove pr_warn from real mode to a more delayed\n\tcontext, where its OK to warn.\n\t- Add a trivial patch to align prints of physical\n\tand effective address\nChangelog v1:\n\t- address review comments from Nick and Mahesh\n\t(initialization of pfn and more comments on failure\n\twhen addr_to_pfn() or anaylse_instr() fail)\n\t- Hookup ierrors to the framework as well\n\t(comments from Mahesh)\n\nBalbir Singh (4):\n powerpc/mce.c: Remove unused function get_mce_fault_addr()\n powerpc/mce: Hookup derror (load/store) UE errors\n powerpc/mce: Hookup ierror (instruction) UE errors\n powerpc/mce: hookup memory_failure for UE errors\n\n arch/powerpc/include/asm/mce.h | 4 +-\n arch/powerpc/kernel/mce.c | 112 +++++++++++++++++++++++++---------------\n arch/powerpc/kernel/mce_power.c | 103 +++++++++++++++++++++++++++++++++---\n 3 files changed, 165 insertions(+), 54 deletions(-)"}
