Subject: linux-next: manual merge of the idle tree with Linus' tree

Hi Len,

Today's linux-next merge of the idle tree got a conflict in
arch/x86/include/uapi/asm/msr-index.h between commit 2f86dc4cddcb
("intel_pstate: Add support for HWP") from Linus' tree and commit
a8b65b07d753 ("tools/power turbostat: decode MSR_*_PERF_LIMIT_REASONS")
from the idle tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
Stephen Rothwell                    sfr@...b.auug.org.au
