2018-04-17s390/signal: cleanup uapi struct sigactionMartin Schwidefsky1-7/+16
The struct sigaction for user space in arch/s390/include/uapi/asm/signal.h is ill defined. The kernel uses two structures 'struct sigaction' and 'struct old_sigaction', the correlation in the kernel for both 31 and 64 bit is as follows sys_sigaction -> struct old_sigaction sys_rt_sigaction -> struct sigaction The correlation of the (single) uapi definition for 'struct sigaction' under '#ifndef __KERNEL__': 31-bit: sys_sigaction -> uapi struct sigaction 31-bit: sys_rt_sigaction -> no structure available 64-bit: sys_sigaction -> no structure available 64-bit: sys_rt_sigaction -> uapi struct sigaction This is quite confusing. To make it a bit less confusing make the uapi definition of 'struct sigaction' usable for sys_rt_sigaction for both 31-bit and 64-bit. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2017-11-02License cleanup: add SPDX license identifier to uapi header files with no ↵Greg Kroah-Hartman1-0/+1
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.
