3b99ee5751c2dfa4b88bb00f573c78735563c4d7 | Analyze and fix the following issue in the Linux kernel code: fbdev: Add Kconfig options to select different fb_ops helpers | Problem Details:
Many fbdev drivers use the same set of fb_ops helpers. Add Kconfig
options to select them at once. This will help with making DRM's
fbdev emulation code more modular, but can also be used to simplify
fbdev's driver configs.

If an IOMMU domain was never attached, it lacks any linkage to the
actual IOMMU hardware. Attempting to do flush_iotlb_all() on it will
result in a NULL pointer dereference. This seems to happen after the
recent IOMMU core rework in v6.4-rc1.

If we switch display and update cursor together, it could lead to
modeset failed because of concurrent access to IO registers.
Add lock protection in DP's edid access to avoid this problem.
