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...

TCG variable type checking.

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.

i386/SVM: return amount of ASIDs

With SVM the TLB supports tagging to distinguish TLB entries from
different virtual CPUs. This tag is called an ASID. The amount of ASIDs is
given in EBX of the SVM-CPUID-leaf. Currently we return 0, which might
break hypervisors. Let's better return something >0 here, say 0x10....

target-i386: Add Core Duo Definition

This patch adds a CPU definition for the Core Duo CPU. I tried to
resemble the original as closely as possible and document what features
are missing still. This patch enables the use of a recent CPU definition
on 32 bit platforms....

Do not use load_seg_vm to load CS in real mode iret handling

load_seg_vm calls cpu_x86_load_seg_cache which updates hflags of
current env, real hardware doesn't do this, nor the code that handles
real mode lret/lcall/ljmp.

This unbreaks "unreal mode" and makes QEMU the first emulator being...

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...

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.

Core 2 Duo specification (Alexander Graf).

This patch adds a Core 2 Duo CPU to the available CPU types. The CPU
definition tries to resemble a real CPU as good as possible, whilst not
exposing features qemu does not implement.
The patch also includes some minor additions that Core 2 Duo CPUs have:...

Fix up pxe boot (Glauber Costa)

As discussed in
http://lists.gnu.org/archive/html/qemu-devel/2008-08/msg00667.html,
current pxe boot is broken for some use cases. The problem
goes away if we reduce the number of allowed bits in the address space
to 32 (which has the side effect of reducing guest max mem size to 4Gb)....
