Subject: tools/power turbostat: update PERF_LIMIT_REASONS decoding
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e33cbe852de48c313a8a52686765c58a711dd9e4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

tools/power turbostat: update PERF_LIMIT_REASONS decoding

cosmetic only.

order the decoding of MSR_PERF_LIMIT_REASONS bits
from MSB to LSB -- which you notice when more than 1 bit is set
and you are, say, comparing the output to the documentation...
