Now that the macro name doesn't make sense, change it and LWSYNC_ON_SMP to better explain what the barriers are doing.

asm-generic: rename atomic.h to atomic-long.h 2009-06-11T19:02:17+00:00 Arnd Bergmann arnd@arndb.de 2009-05-13T22:56:29+00:00 72099ed2719fc5829bd79c6ca9d1783ed026eb37 The existing asm-generic/atomic.h only defines the atomic_long type. This renames it to atomic-long.h so we have a place to add a truly generic atomic.h that can be used on all non-SMP systems.

powerpc: Tell gcc when we clobber the carry in inline asm 2008-11-19T05:04:28+00:00 Paul Mackerras paulus@samba.org 2008-11-05T18:39:27+00:00 efc3624c9419cad3cca93dfabb7b12664773d2b1 We have several instances of inline assembly code that use the addic or addic. instructions, but don't include XER in the list of clobbers. The addic and addic. instructions affect the carry bit, which is in the XER register. This adds "xer" to the list of clobbers for those inline asm statements that use addic or addic. and didn't already have it. Signed-off-by: Paul Mackerras <paulus@samba.org>
