For those of you with older Intel processors (without FlexPriority) or
with AMD processors, this release merges the apic tpr acceleration
patch, which improves Windows ACPI performance dramatically. Currently
this is disabled for smp guests.

Changes from kvm-57:
- add mmu statistics
- log data on write to unimplemented msr
- fix memory corruption (mapcount error) after host fork() (Izik Eidus)
- improve preempt notifier emulation on older kernels (Andrea Arcangeli)
- refactor IDE CHS guessing (Anthony Liguori)
- testsuite improvements
- apic tpr acceleration for Windows guests
- disabled on smp for now
- fix warnings due to qemu merge (Carlo Marcelo Arenas Belon)
- improve support for older kernels (Carlo Marcelo Arenas Belon)
- icache sync in qemu after dma for more archs (Christian Ehrhardt)
- simplify mmio callback (Christian Ehrhardt)
- align gdbstub with qemu-cvs (Jan Kiszka)
- fix compile if kernel/include/asm/ preexists (Sheng Yang)
- fix migration on i386 hosts (Uri Lublin)
- qemu ia64 adjustments (Zhang Xiantao)

Notes:
If you use the modules bundled with kvm-58, you can use any version
of Linux from 2.6.17 upwards.
If you use the modules bundled with Linux 2.6.20, you need to use
kvm-12.
If you use the modules bundled with Linux 2.6.21, you need to use
kvm-17.
Modules from Linux 2.6.22 and up will work with any kvm version from
kvm-22. Some features may only be available in newer releases.
For best performance, use Linux 2.6.23-rc2 or later as the host.
