lib/Kconfig.debug: Debug Lockups and Hangs: keep SOFTLOCKUP options together
Keep all of the SOFTLOCKUP kconfig symbols together (instead of injecting the HARDLOCKUP symbols in the midst of them) so that the config tools display them with their dependencies. Tested with 'make {menuconfig/nconfig/gconfig/xconfig}'. Link: http://lkml.kernel.org/r/6be2d9ed-4656-5b94-460d-7f051e2c7570@infradead.org Fixes: 05a4a9527931 ("kernel/watchdog: split up config options") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
