Both patches have been tested for one week on the debian buildd servers and prevent random segmentation faults. The patch from me fixes a crash at boot inside the TLB measuring code on SMP machines with PA8000-PA8700 CPUs (specifically A500-44 and J5000 servers). Thanks, Helge ---------------------------------------------------------------- Helge Deller (1): parisc: Fix TLB related boot crash on SMP machines John David Anglin (2): parisc: Purge TLB before setting PTE parisc: Remove unnecessary TLB purges from flush_dcache_page_asm and flush_icache_page_asm arch/parisc/include/asm/pgtable.h | 8 ++++---- arch/parisc/kernel/cache.c | 11 +++++++++++ arch/parisc/kernel/pacache.S | 22 +--------------------- 3 files changed, 16 insertions(+), 25 deletions(-)
