Subject: [PATCH] x86/timers: Move simple_udelay_calibration past init_hypervisor_platform
Date: Wed, 24 May 2017 20:04:41 +0200
Message-ID: <5e89fe60-aab3-2c1c-aba8-32f8ad376189@siemens.com> (raw)
This ensures that adjustments to x86_platform done by the hypervisor
setup is already respected by this simple calibration.
The current user of this, introduced by 1b5aeebf3a92 ("x86/earlyprintk:
Add support for earlyprintk via USB3 debug port"), comes much later
into play.
