This patchset is actually a better alternative to http://www.spinics.net/lists/arm-kernel/msg430726.html, which allows to keep piggy-backed LRs. The idea is based on the fact that our code also maintains LR state in elrsr, and this information is enough to track LR usage. In case of problems this series can be applied partially, each patch is a complete refactoring step on its own. Thanks to Andre Przywara for pinpointing some 4.3+ specifics. This version has been tested on SMDK5410 development board (Exynos5410 SoC). v2 => v3: - Removed two unused variables in __kvm_vgic_flush_hwstate(), overlooked leftover from v1. v1 => v2: - Rebased to kvmarm/next of 23.10.2015. - Do not use vgic_retire_lr() for initializing ELRSR bitmask, because now it also handles pushback of PENDING state, use direct initialization instead (copied from Andre's patchset). - Took more care about vgic_retire_lr(), which has deserved own patch.
