6f52b16c5b 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.

242fc35290 sched/headers/uapi: Fix linux/sched/types.h userspace compilation errors
Consistently use types provided by <linux/types.h> to fix the following
linux/sched/types.h userspace compilation errors:

  /usr/include/linux/sched/types.h:57:2: error: unknown type name 'u32'
    u32 size;
  ...
  u64 sched_period;

e2d1e2aec5 sched/headers: Move various ABI definitions to <uapi/linux/sched/types.h>
Move scheduler ABI types (struct sched_attr, struct sched_param, etc.) into
the new UAPI header.

This further reduces the size and complexity of <linux/sched.h>.

ae7e81c077 sched/headers: Prepare for new header dependencies before moving code to <uapi/linux/sched/types.h>
We are going to move scheduler ABI details to <uapi/linux/sched/types.h>,
which will be used from a number of .c files.

Create empty placeholder header that maps to <linux/types.h>.

Include the new header in the files that are going to need it.
