kfraser@localhost.localdomain aeb2e1298b PV-on-HVM: Add new ioreq 'invalidate' for zapping ioemu-dm mapccahe 
after balloon operations in an HVM guest.

This removes the I/O port hack from the guest OS, and from ioemu.

Also we flush on reservation *increases* as well as decreases. This is
necessary until qemu-dm can demand-fault page mappings into existing
valid buckets.

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.
