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...

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...

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....

SYSENTER/SYSEXIT IA-32e implementation (Alexander Graf).

On Intel CPUs, sysenter and sysexit are valid in 64-bit mode. This patch
makes both 64-bit aware and enables them for Intel CPUs.
Add cpu save/load for 64-bit wide sysenter variables.

Correctly save and restore env->a20_mask now that it is a 64-bit
variable. Noticed by Erik de Castro Lopo.
