This was on my todo list and Eugeniy's patch in this area pestered me to finish it finally. The ideas it to cleanup/tidyup ancient do_page_fault() code and make it more readable and hopefully better generated code. There are only a few/subtle functional changes - Eugeniy's fix to prevent user space looping - reduction in mmap_sem hold times Also this could have been 1 single patch but this is tricky part of mm handling so better done as bite sized pieces to track down any regressions Eugeniy Paltsev (1): ARC: mm: SIGSEGV userspace trying to access kernel virtual memory Vineet Gupta (8): ARC: mm: do_page_fault refactor #1: remove label @good_area ARC: mm: do_page_fault refactor #2: remove short lived variable ARC: mm: do_page_fault refactor #3: tidyup vma access permission code ARC: mm: do_page_fault refactor #4: consolidate retry related logic ARC: mm: do_page_fault refactor #5: scoot no_context to end ARC: mm: do_page_fault refactor #6: error handlers to use same pattern ARC: mm: do_page_fault refactor #7: fold the various error handling ARC: mm: do_page_fault refactor #8: release mmap_sem sooner arch/arc/mm/fault.c | 192 +++++++++++++++++++++------------------------------- 1 file changed, 79 insertions(+), 113 deletions(-) -- 2.7.4 _______________________________________________ linux-snps-arc mailing list linux-snps-arc@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/linux-snps-arc
