Subject: [RFC PATCH v2 00/27] Compile test and fixes for exported header files

This patch series introduces a simple compile test for exported header files
and fixes a few example findings from the test.

It's a bit of a pain to see headers in userspace with unknown kernel
definitions, incomplete header file dependencies and other compile failures.

The test was simple until I found out that some kernel headers depend on
gcc and libc headers.  Now there's a hack to copy libc headers and hard coded
path to gcc headers for the tests but hopefully in further iterations I can
make this more portable. Maybe there's a chance that a test like this
could be added into 'headers_chech_all' or even 'headers_install'.
Further uses for compiling headers might be ABI checkers but I've not
explored this any further.

The fixed issues are just a few samples I've been able to fix so far.
I'm hoping to get some feedback if fixes or the tests are doing something
completely wrong. Some problems like with via_drm.h seem several years old but
have not been fixed thus far:

Mikko Rapeli (27):
  Compile test script for exported header files
  scripts/ add verbose option to make calls if defined
  Makefile: propagate verbose options enhance error handling
  drm.h: include stdlib.h in userspace
  drm_mode.h: include stdint.h and linux/types.h in userspace
  exynos_drm.h: include stdint.h in userspace
  nouveau_drm.h: include stdint.h in userspace
  radeon_drm.h: include stdint.h in userspace
  vmwgfx_drm.h: include drm/drm.h instead of drm.h in userspace
  dm-log-userspace.h: include stdint.h in userspace
  hsi_char.h: include stdint.h in userspace
  ebtables.h: include stdint.h in userspace
  cld.h: include stdint.h in userspace
  rds.h: include stdint.h in userspace
  sctp.h: include stdint.h in userspace
  scsi_bsg_fc.h: include stdint.h in userspace
  scsi_netlink.h: include stdint.h in userspace
  scsi_netlink_fc.h: include stdint.h in userspace
  hdspm.h: include stdint.h in userspace
  gntalloc.h: include stdint.h in userspace
  gntdev.h: include stdint.h in userspace
  r128_drm.h: include drm/drm.h
  via_drm.h: include linux/types.h instead of non-existing
  via_drm.h: hide struct via_file_private in userspace
  savage_drm.h: include <drm/drm.h>
  sis_drm.h: hide sis_file_private in userspace
