MTRR support on x86 (Carl-Daniel Hailfinger)

The current codebase ignores MTRR (Memory Type Range Register)
configuration writes and reads because Qemu does not implement caching.
All BIOS/firmware in know of for x86 do implement a mode called
Cache-as-RAM (CAR) which locks down the CPU cache lines and uses the CPU...

x86 cleanup

Remove some unnecessary includes, add needed includes, move prototypes to
cpu.h to suppress missing prototype warnings.

Remove unused functions and prototypes (cpu_x86_flush_tlb, cpu_lock,
cpu_unlock, restore_native_fp_state, save_native_fp_state)....

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...

Refactor translation block CPU state handling (Jan Kiszka)

This patch refactors the way the CPU state is handled that is associated
with a TB. The basic motivation is to move more arch specific code out
of generic files. Specifically the long #ifdef clutter in tb_find_fast()...

Add KVM support to QEMU

This patch adds very basic KVM support. KVM is a kernel module for Linux that
allows userspace programs to make use of hardware virtualization support. It
current supports x86 hardware virtualization using Intel VT-x or AMD-V. It...

Split CPUID from op_helper

KVM needs to call CPUID from outside of the TCG code. This patch
splits out the CPUID logic into a separate helper that both the op
helper and KVM can call.

My core2duo patch introduced a vague statement of "missing features" in
the CPUID specification. This patch addresses this by specifying exactly
what is missing.
While going along the missing CPUID entries I also stumbled across
invalid and missing CPUID #defines while comparing them to the Intel...
