* License cleanup: add SPDX license identifier to uapi header files with no ↵Greg Kroah-Hartman2017-11-021-0/+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.

* xtensa: provide __NR_sync_file_range2 instead of __NR_sync_file_rangeMax Filippov2015-03-041-1/+1
| | | | | | | | | | | | | xtensa actually uses sync_file_range2 implementation, so it should define __NR_sync_file_range2 as other architectures that use that function. That fixes userspace interface (that apparently never worked) and avoids special-casing xtensa in libc implementations. See the thread ending at http://lists.busybox.net/pipermail/uclibc/2015-February/048833.html for more details. Cc: stable@vger.kernel.org Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

| | | | | | | | | Userspace actually passes single parameter (path name) to the umount syscall, so new umount just fails. Fix it by requesting old umount syscall implementation and re-wiring umount to it. Cc: stable@vger.kernel.org Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

* xtensa: allow multi-inclusion for uapi/unistd.hChris Zankel2012-10-251-11/+3
| | | | | | | | | | | Xtensa implements a method that allows to generate a arbitrary output for each system call by defining the __SYSCALL(number, function, num_args). This usually requires to include uapi/unistd.h twice. Instead of removing the guard agains multiple inclusion entirely, allow to include unistd.h again only if __SYSCALL is defined. Note that __SYSCALL gets always undefined at the end of the file. Signed-off-by: Chris Zankel <chris@zankel.net>
