Subject: [PATCH 17/50] KVM: Remove unnecessary ->decache_regs() call
Date: Thu, 26 Jun 2008 15:27:59 +0300 [thread overview]
Message-ID: <1214483312-9265-18-git-send-email-avi@qumranet.com> (raw)
In-Reply-To: <1214483312-9265-1-git-send-email-avi@qumranet.com>
Since we aren't modifying any register, there's no need to decache
the register state.
