Furthermore we now export flush_cache_page() which is needed (indirectly) by the lustre filesystem. The other patches remove unused functions and optimizes the page fault handler to only evaluate variables if needed, which again protects against possible kernel crashes. Thanks, Helge ---------------------------------------------------------------- Geert Uytterhoeven (1): parisc: Export flush_cache_page() (needed by lustre) Helge Deller (4): parisc: remove unused syscall_ipi() function. parisc: mark parisc_terminate() noreturn and cold. parisc: fix interruption handler to respect pagefault_disable() parisc: let probe_kernel_read() capture access to page zero Jiang Liu (1): parisc: kill SMP single function call interrupt John David Anglin (1): parisc: optimize variable initialization in do_page_fault arch/parisc/include/asm/traps.h | 2 +- arch/parisc/kernel/cache.c | 1 + arch/parisc/kernel/smp.c | 8 +------- arch/parisc/kernel/traps.c | 11 +++-------- arch/parisc/lib/memcpy.c | 15 ++++++++++++++- arch/parisc/mm/fault.c | 15 ++++++++++----- 6 files changed, 30 insertions(+), 22 deletions(-)
