kfraser@localhost.localdomain 6b5e36a305 linux: improve x86 page table handling performance 
Where possible,
- use hypercalls instead of writing to read-only pages
- fold TLB flushes into page table update hypercalls
- on PAE, use single-access updates instead of two-access ones

The single change to PAE pte_clear() yields a 25-30% boost for kernel
builds on a 4x2x2 CPUs, 8Gb box; the other changes together yield
improvements of 2-5%.

Also, adjust backward compatibility handling in a few more places.

Keir Fraser 7ae14cd969 xen: No need for shadow_drop_references() in remove_page(). 
Because:
    guest_physmap_remove_page()
 -> p2m_remove_page()
 -> set_p2m_entry()
 -> paging_write_p2m_entry()
 -> shadow_write_p2m_entry()

And shadow_write_p2m_entry() calls sh_remove_all_*() fns.

kfraser@localhost.localdomain 8a54eb9690 hvm svm: Avoid intercepts when accessing a number of architectural MSRs. 
1. Removes intercept of guest-specific MSRs
MSR_IA32_SYSENTER_{CS,ESP,EIP}, MSR_{L,C,}STAR, MSR_SYSCALL_MASK,
MSR_SHADOW_GS_BASE.

2. Removes code to deal with those intercepts, as well as the
FS/GS-base. Since long_mode_do_msr_read now became essentially a
switch of a single case + default, I removed the entire function and
inlined the remaining single case-statement into the original
MSR-access function.

Christian Limpach 2bdbd3e193 [hvm] Keep track of time offset between domain time and dom0 time. 
On each rtc time update from the hvm domain, we send an ioreq request
to qemu which then updates the time offset xenstore entry.  The time
offset is preserved across reboot and can be set on domain creation
by setting the rtc_timeoffset variable in a config file.

If a domain fails to restore, report back an error and close the
