Thanks, applied to our next/late branch which I plan to send in tomorrow. -Olof

Thanks for picking the series. Heiko
This small series addresses a couple of runtime PM issues I've spotted while running 4.18 on a Chromebook Plus (kevin, rk3399) platform, and specifically doing kexec. In order to avoid making a complete mess of the IOMMU code, Heiko has requested that all RK platforms would select CONFIG_PM, which simplifies a lot of things. I've kept 32 and 64bit patches separate, but feel free to squash them into on if that's more convenient. Note that even with these patches, kexec is still fairly broken on rk3399, as the VOP is never turned off (see [1] for a fix). [1] https://www.spinics.net/lists/arm-kernel/msg670229.html * From v1: - Collected RBs from Heiko - Added two patches forcing CONFIG_PM on all Rockchip platforms at Heiko's request, following the example set by Tegra platforms.
