Hi all, this series gets rid of playing with the address limit in the exec and coredump code. Most of this was fairly trivial, the biggest changes are those to the spufs coredump code. Changes since v5: - fix uaccess under spinlock in spufs (Jeremy) - remove use of access_ok in spufs Changes since v4: - change some goto names as suggested by Linus Changes since v3: - fix x86 compilation with x32 in the new version of the signal code - split the exec patches into a new series Changes since v2: - don't cleanup the compat siginfo calling conventions, use the patch variant from Eric with slight coding style fixes instead. Changes since v1: - properly spell NUL - properly handle the compat siginfo case in ELF coredumps
