From e32025a56403df4386cd61a741c0a36afe79ae8a Mon Sep 17 00:00:00 2001 From: Marcelo Tosatti Date: Mon, 11 Jun 2012 23:18:33 -0300 Subject: x86: kvmclock: remove check_and_clear_guest_paused warning CPU offline path calls the hrtimer interrupt handler with interrupts disabled, without touching preempt_count, triggering this warning. Remove the warning since it is supposed to be used from hrtimer interrupt context only.
