x86/cpufeature: Carve out X86_FEATURE_*

2018-07-17T09:31:44+00:00

commit cd4d09ec6f6c12a2cc3db5b7d8876a325a53545b upstream Move them to a separate header and have the following dependency: x86/cpufeatures.h <- x86/processor.h <- x86/cpufeature.h This makes it easier to use the header in asm code and not include the whole cpufeature.h and add guards for asm.

x86/headers: Don't include asm/processor.h in asm/atomic.h

2018-07-17T09:31:44+00:00

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 Signed-off-by: Peter Zijlstra (Intel) Cc: Arnaldo Carvalho de Melo Cc: Jiri Olsa Cc: Linus Torvalds Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Stephane Eranian Cc: Thomas Gleixner Cc: Vince Weaver Cc: rostedt@goodmis.org Link: http://lkml.kernel.org/r/1449018060-1742-1-git-send-email-andi@firstfloor.org Signed-off-by: Ingo Molnar Signed-off-by: Srivatsa S.

lib/atomic64_test.c: convert printk(KERN_INFO to pr_info

2014-06-04T23:54:19+00:00

Convert printk to current pr_foo() logging functions. Also add pr_fmt based on KBUILD_MODNAME to avoid repeating prefix. Prefix is now "atomic64_test: " Signed-off-by: Fabian Frederick Cc: Luca Barbieri Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

atomic64_test: simplify the #ifdef for atomic64_dec_if_positive() test

bug.h: add include of it to various implicit C users

2012-02-29T22:15:08+00:00

With bug.h currently living right in linux/kernel.h there are files that use BUG_ON and friends but are not including the header explicitly. Fix them up so we can remove the presence in kernel.h file. Signed-off-by: Paul Gortmaker
