[PATCH] bitops: generic {,test_and_}{set,clear,change}_bit() This patch introduces the C-language equivalents of the functions below: void set_bit(int nr, volatile unsigned long *addr); void clear_bit(int nr, volatile unsigned long *addr); void change_bit(int nr, volatile unsigned long *addr); int test_and_set_bit(int nr, volatile unsigned long *addr); int test_and_clear_bit(int nr, volatile unsigned long *addr); int test_and_change_bit(int nr, volatile unsigned long *addr); In include/asm-generic/bitops/atomic.h This code largely copied from: include/asm-powerpc/bitops.h include/asm-parisc/bitops.h include/asm-parisc/atomic.h Signed-off-by: Akinobu Mita <mita@miraclelinux.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Add #includes needed to permit the removal of asm/system.h asm/system.h is a cause of circular dependency problems because it contains commonly used primitive stuff like barrier definitions and uncommonly used stuff like switch_to() that might require MMU definitions. asm/system.h has been disintegrated by this point on all arches into the following common segments: (1) asm/barrier.h Moved memory barrier definitions here. (2) asm/cmpxchg.h Moved xchg() and cmpxchg() here. #included in asm/atomic.h. (3) asm/bug.h Moved die() and similar here. (4) asm/exec.h Moved arch_align_stack() here. (5) asm/elf.h Moved AT_VECTOR_SIZE_ARCH here. (6) asm/switch_to.h Moved switch_to() here. Signed-off-by: David Howells <dhowells@redhat.com>

locking: Convert raw_spinlock to arch_spinlock The raw_spin* namespace was taken by lockdep for the architecture specific implementations. raw_spin_* would be the ideal name space for the spinlocks which are not converted to sleeping locks in preempt-rt. Linus suggested to convert the raw_ to arch_ locks and cleanup the name space instead of using an artifical name like core_spin, atomic_spin or whatever No functional change.
