From 9f08890ab906abaf9d4c1bad8111755cbd302260 Mon Sep 17 00:00:00 2001 From: Joao Martins Date: Wed, 8 Nov 2017 17:19:55 +0000 Subject: x86/pvclock: add setter for pvclock_pvti_cpu0_va Right now there is only a pvclock_pvti_cpu0_va() which is defined on kvmclock since: commit dac16fba6fc5 ("x86/vdso: Get pvclock data from the vvar VMA instead of the fixmap") The only user of this interface so far is kvm. This commit adds a setter function for the pvti page and moves pvclock_pvti_cpu0_va to pvclock, which is a more generic place to have it; and would allow other PV clocksources to use it, such as Xen. While moving pvclock_pvti_cpu0_va into pvclock, rename also this function to pvclock_get_pvti_cpu0_va (including its call sites) to be symmetric with the setter (pvclock_set_pvti_cpu0_va).
