tdeegan@york.uk.xensource.com 49f7c7364e Replace shadow pagetable code with shadow2. 2006-08-16 17:02:35 +01:00
shand@kneesaa.uk.xensource.com b687b766ae Fail save if we have an out-of-sync P2M/M2P (since otherwise the restore 
will fail later). 

A better fix would be to tolerate temporary out-of-sync situations so we 
can make a nicer fix to the kunmap_atomic() iossue (c/f -unstable csets 
10529 & 10533) but this requires some more thought.

kaf24@firebug.cl.cam.ac.uk 2928514138 [LIBXC] Convert all printf/fprintf uses to use a macro instead. 
Thus all can be disabled at compile time. It would be easy to
make enabling/disabling a run-time option too.

pae_pgdir_above_4gb tp guests that have enabled this vmassist.

emellor@leeni.uk.xensource.com 3a7a9bda1b Extend the xc_linux_save interface to take a callback function for handling the 
suspend, and push the printf("suspend") out of xc_linux_save and into xc_save.
This means that xc_linux_save can be used without the xc_save wrapper if
desired.

Rationalise x86 CRn guest state into a ctrlreg array in the per-vcpu
context structure. Most noticeably this means the pt_base field has
gone away -- replaced by ctrlreg[3] (CR3). VCPU_guest_stts is also
gone -- it was never arch-independent anyway.
