Actually, it wasn''t too hard to work out. This bisection is misleading
though, as it''s zeroed in on the RCU locking bug, which is already
fixed.
The bug is actually in a later changeset which modifies hvmloader.

Looking at the hvmloader/pci.c changes, the unconditional assignment to
low_mem_pgend after the loop is obviously wrong. As is removing the handling
for high_mem_pgend==0. I checked in a reworked version that is closer to the
original code. 

Hopefully our tests will work again now.
