[PATCH v2 112/144] KVM: selftests: Consolidate KVM_{G,S}ET_ONE_REG helpers
From: Sean Christopherson
Date: Thu Jun 02 2022 - 21:02:12 EST
Rework vcpu_{g,s}et_reg() to provide the APIs that tests actually want to
use, and drop the three "one-off" implementations that cropped up due to
the poor API.
Ignore the handful of direct KVM_{G,S}ET_ONE_REG calls that don't fit the
APIs for one reason or another.
No functional change intended.
