parent[PATCH] kbuild: improve option checking, Kbuild.include cleanup (diff)
[PATCH] kbuild: correctly skip tilded backups in localversion files
Tildes as in path as in filenames are handled correctly now: only files, containing tilde '~', are backups, thus are not valid. [KJ]: Definition of `space' was removed, scripts/Kbuild.include has one. That definition was taken right from the GNU make manual, while Kbuild's version is original.
