Alex Deucher 70b5c5aae5 Revert "drm/amdgpu: use the kernel zone memory size as the max remote memory in amdgpu"
This reverts commit a693e050ed.

This breaks on systems with huge amounts of system memory as we do not have
enough vram to store the page tables.  Additionally, this is less of an issue
with the recent gtt manager changes.

Edward O'Callaghan 01615881ff amdgpu: Wrap dev_err() calls on vm faults with printk_ratelimit()
It can be the case that upon GPU page faults we start trashing
the logs, and so let us ratelimit here to avoid that.

V2. Fix issue where calling dev_err_ratelimited separately for
    each line means that some lines corresponding to a single
    VM fault may or may not appear depending on the rate.

Alex Deucher a125510721 drm/amdgpu: rework IP block registration (v2)
This makes it easier to replace specific IP blocks on
asics for handling virtual_dce, DAL, etc. and for building
IP lists for hw or tables.  This also stored the status
information in the same structure.

v2: split out spelling fix into a separate patch
    add a function to add IPs to the list
