Joerg, what was the reason the initial npt implementation did not do
lazy fpu switching?
The lazy fpu switching code needed cr3 accesses to be intercepted. With
NPT this was the only reason left to intercept cr3 so I decided to
switch lazy fpu switching off and don't intercept cr3 accesses.
Oh. In fact the interaction of cr3 intercepts with lazy fpu was a
mistake which this patchset removes; I'll replace cr0 intercepts with
selective cr0 write intercept in a new patch.
