The POHMELFS filesystem was removed in 2012 by commit 6743531986
("staging: pohmelfs: remove drivers/staging/pohmelfs") promising that
a newer version will be included to the kernel, but unfortunately
it didn't happen.
Since likely any delopment of the filesystem is halted, the change removes
the abandoned POHMELFS documentation from the kernel tree.

When vbox_set_up_input_mapping() gets called the first crtc might be

Instead of using the fb from the crtc with id 0, just use the fb from

The fbdev compat fb gets pinned into VRAM at creation and then gets pinned
a second time when set as scanout buffer and unpinned when replaced, this
