2010-05-19panic: Allow warnings to set different taint flagsBen Hutchings
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 entriesHeiko Carstens
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 macroHeiko Carstens
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>

2008-12-25[S390] remove warnings with functions ending in BUGMartin Schwidefsky
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.
