There are two acks, but I wasn't sure if I was supposed to collect them in the patches or not. Arnd Bergman acked #1 and #7. Changes since v3 (<1442271047-4908-1-git-send-email-palmer@dabbelt.com>) * #4 is very different: rather than defining a canonical value for MAP_UNINITIALIZED, it just punts on the problem and lets arch maintainers deal with it. There's still an #ifndef MAP_UNINITIALIZED in there, but that shouldn't get triggered by anything because the arch headers should set it to whatever they actually want. * #11 defines MAX_RAW_MINORS to 2^20 instead of 2^16. * #13 moves the variable around a bit so it gets initialized. I forgot I was in perl and not C :). Changes since v2 (<1441832902-28993-1-git-send-email-palmer@dabbelt.com>) * Patch set renamed. * #2 is rewritten to use sys_ni.c instead of an #ifdef * #3, #6, #8, #9, #10, and #11 no longer use "#ifdef __KERNEL__" but have instead moved the offending lines to the correct, kernel-only files. * #4 has been rewritten to always define MAP_UNINITIALIZED to non-zero, rather than defining it to zero when in userspace. * #5 got a whole lot longer -- rather than just always hiding these fields from userspace, there is now a second "struct elf_fdpic_prstatus" structure. This should allow userspace to parse core dumps correctly. * Rebased onto 9c488de24f7264f08d341024bffdd637b4d04c96. Changes since v1 (<1441152610-22566-1-git-send-email-palmer@dabbelt.com>) * All patches but #1 were added.
