License cleanup: add SPDX license identifier to uapi header files with no license Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

y2038: parisc: Extend sysvipc data structures parisc, uses a nonstandard variation of the generic sysvipc data structures, intended to have the padding moved around so it can deal with big-endian 32-bit user space that has 64-bit time_t. Unlike most architectures, parisc actually succeeded in defining this right for big-endian CPUs, but as everyone else got it wrong, we just use the same hack everywhere. This takes just take the same approach here that we have for the asm-generic headers and adds separate 32-bit fields for the upper halves of the timestamps, to let libc deal with the mess in user space.

parisc: Fixes and cleanups in kernel uapi header files 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>
