Otherwise if a kms driver calls into drm_vblank_off() more than once before calling drm_vblank_on() again, the redundant calls to vblank_disable_and_save() will call drm_update_vblank_count() while hw vblank counters and vblank timestamping are in a undefined state during modesets, dpms off etc. At least with the legacy drm helpers it is not unusual to get multiple calls to drm_vblank_off and drm_vblank_on, e.g., half a dozen calls to drm_vblank_off and two calls to drm_vblank_on were observed on radeon-kms during dpms-off -> dpms-on transition. We don't no-op calls from atomic modesetting drivers, as they should do a proper job of tracking hw state. Fixes large jumps of the software maintained vblank counter due to the hardware vblank counter resetting to zero during dpms off or modeset, e.g., if radeon-kms is modified to use drm_vblank_off/on instead of drm_vblank_pre/post_modeset(). This fixes a regression caused by the changes made to drm_update_vblank_count() in Linux 4.4. v2: Don't no-op on atomic modesetting drivers, per suggestion of Daniel Vetter.

According to the VT-d specification we need to clear the PPR bit in the Page Request Status register when handling page requests, or the hardware won't generate any more interrupts. This wasn't actually necessary on SKL/KBL (which may well be the subject of a hardware erratum, although it's harmless enough). But other implementations do appear to get it right, and we only ever get one interrupt unless we clear the PPR bit.

Update the mailing list used for development of support for ARM64 Renesas SoCs. This is a follow-up for a similar change for other Renesas SoCs and drivers uses by Renesas SoCs. The ARM64 SoC entry was not updated in that patch as it was not yet present in mainline. The motivation for the mailing list update is that Renesas SoCs are now much wider than the SH architecture and there is some desire from some for the linux-sh list to refocus on discussion of the work on the SH architecture.
