[PATCH v2 0/6] Unmappable DRM client buffers for fbdev emulation
DRM client buffers are permanently mapped throughout their lifetime. This
prevents us from using generic framebuffer emulation for devices with
small dedicated video memory, such as ast or mgag200. With fb buffers
permanently mapped, such devices often won't have enough space left to
display other content (e.g., X11).

[PATCH v3 0/8] Fix connector probing deadlocks from RPM bugs
This is the next version of
https://patchwork.freedesktop.org/series/46815/
With a lot more thought put into it so as to avoid the potential
deadlock scenarios I missed. This also required fixing some bogus DRM
helper usage.
Try and deadlock me now, nouveau. I dare you!!!
