Greeting,
FYI, we noticed a -54.0% regression of phoronix-test-suite.jxrendermark.RadialGradientPaint.1024x1024.operations_per_second due to commit:
How many runs are there on the bad version to ensure the bisect is
repeatable?
test 4 times.

The patch is not expected to have any impact on the machine you are testing on.

What's your code base?
For my side:
1) sync the code to the head of Linux mainline
2) git reset --hard 59dd13ad31
3) git revert 59dd13ad3107
We compare the test result of commit 59dd13ad3107 (step 2) and
2052847b06f8 (step 3, revert 59dd13ad3107), the regression should
related with 59dd13ad3107. Each test case we run 5 times.
