[PATCH] 2.5.40 kbuild bug: mrproper removes files it shouldn't remove

[Mikael Pettersson <mikpe@csd.uu.se>]

'make mrproper' incorrectly deletes *~-style editor backup files
from the top-level directory. This bug was introduced in 2.5.29
when the top-level Makefile was changed to remain in the top-level
directory when invoking DocBook's Makefile:

The problem is that DocBook's 'make clean' rule contains

clean:
	@echo 'Cleaning up (DocBook)'
	@rm -f core *~

so the rm now removes files from the wrong directory. Not good.

Since the top-level Makefile removes all core files, I suggest
simply removing the problematic rm line. Patch below.
