commit 4933f55fe72c86e57efc454dd6e673c7f17af5a3 upstream. libabikfs.a doesn't exist anymore, so we now need to link with libapi.a. Signed-off-by: Andi Kleen Cc: Naoya Horiguchi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

tools/power turbostat: Use $(CURDIR) instead of $(PWD) and add support for O= option in Makefile

2015-05-06T20:03:52+00:00

commit f82263c6989c31ae9b94cecddffb29dcbec38710 upstream. Since commit ee0778a30153 ("tools/power: turbostat: make Makefile a bit more capable") turbostat's Makefile is using [...] BUILD_OUTPUT := $(PWD) [...] which obviously causes trouble when building "turbostat" with make -C /usr/src/linux/tools/power/x86/turbostat ARCH=x86 turbostat because GNU make does not update nor guarantee that $PWD is set. This patch changes the Makefile to use $CURDIR instead, which GNU make guarantees to set and update (i.e. when using "make -C ...") and also adds support for the O= option (see "make help" in your root of your kernel source tree for more details).

tools lib traceevent kbuffer: Remove extra update to data pointer in PADDING

2015-05-06T20:03:52+00:00

commit c5e691928bf166ac03430e957038b60adba3cf6c upstream. When a event PADDING is hit (a deleted event that is still in the ring buffer), translate_data() sets the length of the padding and also updates the data pointer which is passed back to the caller. This is unneeded because the caller also updates the data pointer with the passed back length. translate_data() should not update the pointer, only set the length.

perf tools: Work around lack of sched_getcpu in glibc < 2.6.

commit e1e455f4f4d35850c30235747620d0d078fe9f64 upstream. This patch fixes this build error with glibc < 2.6.

perf tools: Fix perf-read-vdsox32 not building and lib64 install dir

2015-05-06T20:03:52+00:00

commit 76aea7731e7050c066943a1d7456ec6510702601 upstream. Commit: c6e5e9fbc3ea ("perf tools: Fix building error in x86_64 when dwarf unwind is on") removed the definition of IS_X86_64 but not all places using it, with the consequence that perf-read-vdsox32 would not be built anymore, and the default lib install directory was 'lib' instead of 'lib64'. Also needs to go to v3.19. Signed-off-by: H.J.

perf symbols: Define STT_GNU_IFUNC for glibc 2.9 and older.

commit 4e31050f482c02c822b150d71cf1ea5be7c9d6e4 upstream. The token STT_GNU_IFUNC is not available with glibc 2.9 and older. Define this token if it is not already defined.

selftests: Fix build failures when invoked from kselftest target

2015-03-19T15:54:55+00:00

Several tests that rely on implicit build rules fail to build, when invoked from the main Makefile kselftest target. These failures are due to --no-builtin-rules and --no-builtin-variables options set in the inherited MAKEFLAGS. --no-builtin-rules eliminates the use of built-in implicit rules and --no-builtin-variables is for not defining built-in variables. These two options override the use of implicit rules resulting in build failures. In addition, inherited LDFLAGS result in build failures and there is no need to define LDFLAGS. Clear LDFLAGS and MAKEFLAG when make is invoked from the main Makefile kselftest target. Fixing this at selftests Makefile avoids changing the main Makefile and keeps this change self contained at selftests level. Signed-off-by: Shuah Khan Acked-by: Michael Ellerman
