Subsystem:
drm drivers, drm drivers and misc gpu patches, drm drivers for gma500 (poulsbo, moorestown and derivative chipsets), framebuffer core, framebuffer layer, intel drm i915 driver (meteor lake, dg2 and older excluding poulsbo, moorestown and derivative), marvell armada drm support, radeon and amdgpu drm drivers, the rest · Maintainers:

Change the infix for fbdev's I/O-memory helpers from _IO_ to _IOMEM_ to distiguish them from other types of I/O, such as file operations. The helpers operate on memory ranges in the I/O address space and the naming should make this clear. Adapt all users. No functional changes.
