This patch fixes some bugs and partly cleans up the parisc uapi header files to what glibc defined: - compat_semid64_ds was wrong and did not take the endianess into account - ipc64_perm exported userspace types which broke building userspace packages on debian (e.g. trinity) - ipc64_perm needs to use a 32bit mode_t on 64bit kernel - msqid64_ds and semid64_ds needs unsigned longs for various struct members - shmid64_ds exported size_t instead of __kernel_size_t And finally add some compile-time checks for the sizes of those structs to avoid future breakage. Runtime-tested with the Linux Test Project (LTP) testsuite. Cc: <stable@vger.kernel.org> # 3.18+ Reviewed-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Helge Deller <deller@gmx.de>
