Generic headers allow ARCH maintainers to remove all dummy arch/ARCH/include/asm/XXX.h files or, depending on the architecture, include/asm-ARCH/XXX.h (e.g. arch/x86/include/asm/errno.h) that only include the _name equivalent_ include/asm-generic/XXX.h file (e.g. include/asm-generic/errno.h) with _no_ changes. It was called generic headers for short. Arnd Bergmann gave the original idea and asked me to implement it. This is the second implementation with the changes proposed by Sam Ravnborg. To use it just one step is necessary: - Remove all the dummy arch/ARCH/include/asm/XXX.h files (e.g. rm arch/x86/include/asm/errno.h) The scripts/Makefile.headersinst was adapted to avoid errors (due to the removal of header files from their default locations) so it would pass the 'make headers_check'. The generic headers were applyed and tested in x86 (tested in my Notebook with i386_defconfig on kernel 2.6.29-rc8 of 17/Mar/2009 from Linus git tree). It compiled and booted without problems. This approach does not reduce much LOC but, in a rough estimation, it would allow the removal of around 90 dummy header files among all architectures.
