Subject: [PATCH] tools/power turbostat: fix decoding of HWP_STATUS
References: bsc#1012628
Patch-mainline: 6.2.10
Git-commit: 92c25393586ac799b9b7d9e50434f3c44a7622c4

[ Upstream commit 92c25393586ac799b9b7d9e50434f3c44a7622c4 ]

The "excursion to minimum" information is in bit2
in HWP_STATUS MSR. Fix the bitmask used for
decoding the register.
