From 4e420aa94c9e6974533797efd1dd93e779d490c3 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Thu, 5 Jun 2008 16:52:15 +0200 Subject: kbuild: always unifdef files in headers_install* unifdef utility is fast enough to warrant that we always run the scripts through unifdef. This patch runs all headers listed with header-y and unifdef-y through unifdef. Next step is to drop unifdef-y in all Kbuild files and that can now be done in smaller steps.

This revealed a long standing bug where "make headers_check_all" relied on the files in asm/ for the current architecture. So make headers_check_all is now broken by this commit. In addition: o add a simpler way to detect if an arch support exporting header files. o add 'set -e;' so we error out early if make headers_check_all fails. o add sparc64 and cris to arch we do not process in make headers_*_all because: sparc64 - use sparc to export headers cris - is know seriously broken Includes suggestions from: David Woodhouse .

The makefile is adapted to use the perl scrip and changed to operate on all files in a directory. So if one file is changed then all files in the directory is processed. perl were chosen for the helper scripts because this is pure text processing which perl is good at and especially the headers_check.pl script are expected to see changes / new checks implmented. The speed is ~300% faster on this box. And the output generated to the screen is now down to two lines per directory (one for install, one for check) so it is easier to scroll back after a kernel build.

-- cgit v1.2.3 From db1bec4f5271d7799d481cd4d95fdc268bdd7614 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Mon, 16 Jun 2008 21:29:38 +0200 Subject: kbuild: install all headers when arch is changed We see some header files that are selected dependent on the actual architecture so force a reinstallation of all header files when the arch changes. This slows down "make headers_check_all" but then we better reflect reality.
