- before enabling paging VM asks kernel to resize its segments. This
may cause kernel to segfault if APIC is used and an interrupt
happens between this and paging enabled. As these are 2 separate
vmctl calls it is not atomic. This patch fixes this problem. VM does
not ask kernel to resize the segments in a separate call anymore.
The new segments limit is part of the "enable paging" call. It
generalizes this call in such a way that more information can be
passed as need be or the information may be completely different if
another architecture requires this.
