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