* panic: Allow warnings to set different taint flagsBen Hutchings2010-05-191-3/+3
| | | | | | | | | | | | | | | | | 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().

* powerpc: Convert BUG() to use unreachable()David Daney2009-12-181-1/+1
| | | | | | | | | | Use the new unreachable() macro instead of for(;;); Signed-off-by: David Daney <ddaney@caviumnetworks.com> CC: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: Paul Mackerras <paulus@samba.org> CC: linuxppc-dev@ozlabs.org Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* powerpc: Fix asm EMIT_BUG_ENTRY with !CONFIG_BUGBenjamin Herrenschmidt2008-12-161-1/+10
| | | | | | | | | | | Instead of not defining it at all, this defines the macro as being empty, thus avoiding ifdef's in call sites when CONFIG_BUG is not set. Also removes an extra whitespace in the existing definition. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Move include files to arch/powerpc/include/asmStephen Rothwell2008-08-041-0/+121
from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
