s390: make built-in.a not directly depend on *.o.chkbss files

2019-01-28T00:11:17Z

When I was refactoring cmd_ar_builtin in scripts/Makefile.build, I noticed the build breakage of s390. Some Makefiles of s390 add extra dependencies to built-in.a; built-in.a depends on timestamp files *.o.chkbss, but $(AR) does not want to include them into built-in.a. Insert a phony target 'chkbss' in between so that $(AR) can take $(filter-out $(PHONY), $^) as input. While I was here, I refactored Makefile.chkbss a little bit.

s390/build: add *.o.chkbss files to targets list

2018-07-02T10:32:23Z

Adding *.o.chkbss files to targets list makes sure that the kbuild is aware of them and removes them during make clean. Also remove *.o.chkbss file before an actual check, to avoid having stale *.o.chkbss file left even if the check is failed.

s390: add custom target and make path extension optional for .bss check

2018-06-25T08:14:39Z

"chkbss-target" could be now used to override default target .bss check is bound to. Objects to be checked are only path extended when needed. Reviewed-by: Heiko Carstens Signed-off-by: Vasily Gorbik Signed-off-by: Martin Schwidefsky

s390: introduce compile time check for empty .bss section

2018-05-09T08:55:01Z

Introduce compile time check for files which should avoid using .bss section, because of the following reasons: - .bss section has not been zeroed yet, - initrd has not been moved to a safe location and could be overlapping with .bss section.
