[Xen-devel] [PATCH V12 0/5] Fix VGA logdirty related display freezes with altp2m

This series aims to prevent the display from freezing when
enabling altp2m and switching to a new view (and assorted problems
when resizing the display).

The series introduces p2m_{init,free}_logdirty(), allocates a new
logdirty rangeset for each new altp2m, and  propagates (under lock)
changes to all p2ms.

[PATCH V12 1/5] x86/p2m: allocate logdirty_ranges for altp2ms
[PATCH V12 2/5] x86/p2m: refactor p2m_reset_altp2m()
[PATCH V12 3/5] x86/altp2m: fix display frozen when switching to a new view 
[PATCH V12 4/5] p2m: Always use hostp2m when clipping rangesets
[PATCH V12 5/5] p2m: change_type_range: Only invalidate mapped gfns
