[PARISC] Update spinlocks from parisc tree
Neaten up the CONFIG_PA20 ifdefs More merge fixes, this time for SMP Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Prettify the CONFIG_DEBUG_SPINLOCK __SPIN_LOCK_UNLOCKED initializers. Clean up some warnings with CONFIG_DEBUG_SPINLOCK enabled. Fix build with spinlock debugging turned on. Patch is cleaner like this, too. Remove mandatory 16-byte alignment requirement on PA2.0 processors by using the ldcw,CO completer. Provides a nice insn savings. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
