Subject[PATCH v03 00/98] Userspace compile test and fixes for exported uapi header files
Date
v3:
tried to fix all v2 review findings
tried to guess how to fix a few more issue
with a few hacks, 0 files fail and 760 files pass the compile test on 32bit x86

v2:
https://lkml.org/lkml/2015/2/16/521
added cross compiler support with CROSS_COMPILE,
detecting libc and GCC headers from compiler,
more header file fixes

v1:
https://lkml.org/lkml/2014/8/21/665

Users of kernel header files would be happier if they did not contain
kernel specific parts and would contain #include statements for all
other header files that they depend on, and in general would compile.

This patch set introduces a compile test for headers exported to userspace
and then fixes many of the userspace header compilation failures.

Changes are also available in headers_test_v03 branch at github:
https://github.com/mcfrisk/linux/tree/headers_test_v03

The patch set includes some obvious hacks for which I'd like to get some
feedback and suggestions how to properly fix them.

Here's how to run the userspace compile tests:

$ make headers_install && cd usr/include && \
../../scripts/headers_compile_test.sh

Additionally tested an allyesconfig compilation on 32bit x86.
