x86 cleanup
Remove some unnecessary includes, add needed includes, move prototypes tocpu.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)....
Remove FORCE_RET() and RETURN

x86: Debug register emulation (Jan Kiszka)
Built on top of previously enhanced breakpoint/watchpoint support, thispatch adds full debug register emulation for the x86 architecture.
Many corner cases were considered, and the result was successfullytested inside a Linux guest with gdb, but I won't be surprised if one...

Split CPUID from op_helper
KVM needs to call CPUID from outside of the TCG code. This patchsplits out the CPUID logic into a separate helper that both the ophelper and KVM can call.

i386/SVM: return amount of ASIDs
With SVM the TLB supports tagging to distinguish TLB entries fromdifferent virtual CPUs. This tag is called an ASID. The amount of ASIDs isgiven in EBX of the SVM-CPUID-leaf. Currently we return 0, which mightbreak 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 toresemble the original as closely as possible and document what featuresare missing still. This patch enables the use of a recent CPU definitionon 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 ofcurrent env, real hardware doesn't do this, nor the code that handlesreal 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" inthe CPUID specification. This patch addresses this by specifying exactlywhat is missing.While going along the missing CPUID entries I also stumbled acrossinvalid 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 patchmakes 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 CPUdefinition tries to resemble a real CPU as good as possible, whilst notexposing 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 inhttp://lists.gnu.org/archive/html/qemu-devel/2008-08/msg00667.html,current pxe boot is broken for some use cases. The problemgoes away if we reduce the number of allowed bits in the address spaceto 32 (which has the side effect of reducing guest max mem size to 4Gb)....
