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.

asm-generic: add generic sysv ipc headers The ipc64 data structures were originally meant to be architecture specific so that each architecture could add their own optimizations for padding. In the end, most of them just copied the x86 version, and most got that wrong. UClibc expects the x86 anyway, so we might just declare that the default and get rid of the extra copies.

uapi, asm-generic: Use __kernel_ulong_t in uapi struct ipc64_perm x32 IPC system call is the same as x86-64 IPC system call, which uses 64-bit integer for unsigned long in struct ipc64_perm. But x32 long is 32 bit. This patch replaces unsigned long in uapi struct ipc64_perm with __kernel_ulong_t. Signed-off-by: H.J.
