Both were fixed upstream as part of a large non-backportable rewrite. Other stable kernel versions are not affected. cheers Michael Ellerman (1): powerpc/64s: Unmerge EX_LR and EX_DAR Nicholas Piggin (1): powerpc/64/interrupt: Temporarily save PPR on stack to fix register corruption due to SLB miss arch/powerpc/include/asm/exception-64s.h | 37 ++++++++++++++---------- 1 file changed, 22 insertions(+), 15 deletions(-)
