3.16.68-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Andi Kleen <a...@linux.intel.com> commit 153a4334c439cfb62e1d31cee0c790ba4157813d upstream. asm/atomic.h doesn't really need asm/processor.h anymore. Everything it uses has moved to other header files. So remove that include. processor.h is a nasty header that includes lots of other headers and makes it prone to include loops. Removing the include here makes asm/atomic.h a "leaf" header that can be safely included in most other headers. The only fallout is in the lib/atomic tester which relied on this implicit include. Give it an explicit include. (the include is in ifdef because the user is also in ifdef) Signed-off-by: Andi Kleen <a...@linux.intel.com> Signed-off-by: Peter Zijlstra (Intel) <pet...@infradead.org> Cc: Arnaldo Carvalho de Melo <a...@redhat.com> Cc: Jiri Olsa <jo...@redhat.com> Cc: Linus Torvalds <torva...@linux-foundation.org> Cc: Mike Galbraith <efa...@gmx.de> Cc: Peter Zijlstra <pet...@infradead.org> Cc: Stephane Eranian <eran...@google.com> Cc: Thomas Gleixner <t...@linutronix.de> Cc: Vince Weaver <vincent.wea...@maine.edu> Cc: rost...@goodmis.org Link: http://lkml.kernel.org/r/1449018060-1742-1-git-send-email-a...@firstfloor.org Signed-off-by: Ingo Molnar <mi...@kernel.org> [bwh: Backported to 3.16 to avoid a dependency loop; adjusted context] Signed-off-by: Ben Hutchings <b...@decadent.org.uk> --- arch/x86/include/asm/atomic.h | 1 - arch/x86/include/asm/atomic64_32.h | 1 - lib/atomic64_test.c | 4 ++++ 3 files changed, 4 insertions(+), 2 deletions(-) --- a/arch/x86/include/asm/atomic.h +++ b/arch/x86/include/asm/atomic.h @@ -3,7 +3,6 @@ #include <linux/compiler.h> #include <linux/types.h> -#include <asm/processor.h> #include <asm/alternative.h> #include <asm/cmpxchg.h> #include <asm/rmwcc.h> --- a/arch/x86/include/asm/atomic64_32.h +++ b/arch/x86/include/asm/atomic64_32.h @@ -3,7 +3,6 @@ #include <linux/compiler.h> #include <linux/types.h> -#include <asm/processor.h> //#include <asm/cmpxchg.h> /* An 64bit atomic type */ --- a/lib/atomic64_test.c +++ b/lib/atomic64_test.c @@ -16,6 +16,10 @@ #include <linux/kernel.h> #include <linux/atomic.h> +#ifdef CONFIG_X86 +#include <asm/processor.h> /* for boot_cpu_has below */ +#endif + #define INIT(c) do { atomic64_set(&v, c); r = c; } while (0) static __init int test_atomic64(void) {
