	WARN() is used in some places to report firmware or hardware bugs that are then worked-around. These bugs do not affect the stability of the kernel and should not set the flag for TAINT_WARN. To allow for this, add WARN_TAINT() and WARN_TAINT_ONCE() macros that take a taint number as argument. Architectures that implement warnings using trap instructions instead of calls to warn_slowpath_*() now implement __WARN_TAINT(taint) instead of __WARN().

2010-02-26	[S390] bug: use relative pointers in bug table entries	Heiko Carstens	1	-8/+2
	Reduces the size of the bug table entries by 50% on 64bit kernels. Saves around 30kb on a defconfig kernel. s390 version of b93a531e "allow bug table entries to use relative pointers (and use it on x86-64)".

2010-01-13	[S390] bug: implement arch specific __WARN macro	Heiko Carstens	1	-0/+4
	This one will trap, generates shorter code and emits better debug data than the generic version. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-12-05	s390: Convert BUG() to use unreachable()	David Daney	1	-1/+1
	Use the new unreachable() macro instead of for(;;); Signed-off-by: David Daney <ddaney@caviumnetworks.com> Acked-by: Martin Schwidefsky <schwidefsky@de.ibm.com> CC: Heiko Carstens <heiko.carstens@de.ibm.com> CC: linux390@de.ibm.com CC: linux-s390@vger.kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-12-25	[S390] remove warnings with functions ending in BUG	Martin Schwidefsky	1	-1/+4
	Functions which end in a BUG() statement and skip the return statement cause compile warnings on s390, e.g.: mm/bootmem.c: In function 'mark_bootmem': mm/bootmem.c:321: warning: control reaches end of non-void function To avoid the warning add an endless loop to the BUG() macro.
