79c4f6b080 QEMU: MCE: Add MCE simulation to qemu/tcg
- MCE features are initialized when VCPU is intialized according to CPUID.
- A monitor command "mce" is added to inject a MCE.
- A new interrupt mask: CPU_INTERRUPT_MCE is added to inject the MCE.

059b8b1eb6 KVM: x86: Refactor persistent CPU state
This patch aligns the KVM-related layout and encoding of the CPU state
to be saved to disk or migrated with qemu-kvm. The major differences are
reordering of fields and a compressed interrupt_bitmap into a single
number as there can be no more than one pending IRQ at a time.

f8d926e9cd kvm: x86: Save/restore KVM-specific CPU states
Save and restore all so far neglected KVM-specific CPU states. Handling
the TSC stabilizes migration in KVM mode. The interrupt_bitmap and
mp_state are currently unused, but will become relevant for in-kernel
irqchip support. By including proper saving/restoring already, we avoid
having to increment CPU_SAVE_VERSION later on once again.

v2:
 - initialize mp_state runnable (for the boot CPU)

b0a46a333a kvm: Add missing bits to support live migration
This patch adds the missing hooks to allow live migration in KVM mode.
It adds proper synchronization before/after saving/restoring the VCPU
states (note: PPC is untested), hooks into
cpu_physical_memory_set_dirty_tracking() to enable dirty memory logging
at KVM level, and synchronizes that drity log into QEMU's view before
running ram_live_save().

dd5e3b1771 MTRR support on x86, part 2 (Carl-Daniel Hailfinger)
Load and save MTRR state together with machine state.

Add support for the MTRRcap MSR which is used by the latest Bochs BIOS
and some operating systems.

Fix a typo in ext2_feature_name.

With this patch, MTRR emulation should be good enough to not trigger any
sanity checks in well behaved BIOS/kernel code.
Some corner cases for BIOS/firmware usage remain to be implemented, but
that can be deferred to another patch.
Also, MTRR accesses on hardware not supporting MTRRs should cause #GP.
That can be enforced by another patch as well.

01df040b52 x86: Debug register emulation (Jan Kiszka)
Built on top of previously enhanced breakpoint/watchpoint support, this
patch adds full debug register emulation for the x86 architecture.

Many corner cases were considered, and the result was successfully
tested inside a Linux guest with gdb, but I won't be surprised if one
or two scenarios still behave differently in reality.

e5ceb24447 Fix restore of older snapshots for target-i386 on big endian hosts
A target_ulong may be 64-bit.  Passing it to a function expecting a 32-bit
pointer is wrong and unfortunately happens to work for x86.  It won't work on
big endian hosts though.  Change the code to work properly on all hosts.
