The upcoming in-kernel implementations for LinuxKPI based on work on iwlwifi (and other wireless drivers) conflicts in a few places with the drm-kmod graphics work outside the base system. In order to transition smoothly extract the conflicting bits. This included "unaligned" accessor functions, sg_pcopy_from_buffer(), IS_*() macros (to be further restricted in the future), power management bits (possibly no longer conflicting with DRM), and other minor changes. Obtained-from: bz_iwlwifi Sponsored-by: The FreeBSD Foundation MFC after: 3 days Reviewed by: kib, hselasky, manu, bdragon (looked at earlier versions) Differential Revision: https://reviews.freebsd.org/D26598
