Subject: [PATCH 15/21] x86: revert extra time added to check for tsc wraps
|
|
|
|
Reverts extra time duration added to test tsc wraps in
|
|
"x86: implement tsc=directsync for systems without IA32_TSC_ADJUST".
|
|
This duration makes the sanity checking longer in case tsc wraps. Revert
|
|
this to decrease average resume time.
