The first two patches remove the WARN_ON_ONCE(in_nmi) from the vmalloc_fault() function and revert the previous fix, as discussed at the last patch-set. The third patch is an important fix for a silent memory corruption issue found by the trinity fuzzer, which did take a while to track down. But I found it and with the fix the fuzzer already runs for couple of hours now and the VM is still alive. Regards, Joerg Joerg Roedel (3): x86/mm: Remove in_nmi() warning from vmalloc_fault() Revert "perf/core: Make sure the ring-buffer is mapped in all page-tables" x86/kexec: Allocate 8k PGDs for PTI arch/x86/kernel/machine_kexec_32.c | 5 +++-- arch/x86/mm/fault.c | 2 -- kernel/events/ring_buffer.c | 16 ---------------- 3 files changed, 3 insertions(+), 20 deletions(-) -- 2.7.4
