[PATCH 4.4 2/3] x86/cpu: Probe CPUID leaf 6 even when cpuid_level == 6

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Lutomirski <luto@kernel.org>

commit 3df8d9208569ef0b2313e516566222d745f3b94b upstream.

A typo (or mis-merge?) resulted in leaf 6 only being probed if
cpuid_level >= 7.

[PATCH 4.4 3/3] perf tools: Move syscall number fallbacks from perf-sys.h to tools/arch/x86/include/asm/

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnaldo Carvalho de Melo <acme@redhat.com>

commit cec07f53c398f22576df77052c4777dc13f14962 upstream.

And remove the empty tools/arch/x86/include/asm/unistd_{32,64}.h files
introduced by eae7a755ee81 ("perf tools, x86: Build perf on older
user-space as well").

This way we get closer to mirroring the kernel for cases where __NR_
can't be found for some include path/_GNU_SOURCE/whatever scenario.
