This patch implements Supervisor Mode Execution Prevention (SMEP) and
Supervisor Mode Access Prevention (SMAP) for x86. The purpose of the
patch, obviously, is to help kernel developers debug the support for
those features.
A fair bit of the code relates to the handling of CPUID features. The
CPUID code probably would get greatly simplified if all the feature
bit words were unified into a single vector object, but in the
interest of producing a minimal patch for SMEP/SMAP, and because I had
very limited time for this project, I followed the existing style.

We have a problem with how we handle migration with KVM paravirt features.
We unconditionally enable paravirt features regardless of whether we know how
to migrate them.
We also don't tie paravirt features to specific machine types so an old QEMU on
a new kernel would expose features that never existed.
The 1.2 cycle is over and as things stand, migration is broken. Michael has
another series that adds support for migrating PV EOI and attempts to make it
work correctly for different machine types.
After speaking with Michael on IRC, we agreed to take this patch plus 1 & 4
from his series. This makes sure QEMU can migrate PV EOI if it's enabled, but
does not enable it by default.
This also means that we won't unconditionally enable new features for guests
future proofing us from this happening again in the future.

Instead of assuming that we can use irqfds if and only if

The kernel documentation implies that the only thing
you need to use KVM_IRQFD is that KVM_CAP_IRQFD is
advertised, but this seems to be untrue. In particular
the kernel does not (alas) return a sensible error if you
try to set up an irqfd when you haven't created an irqchip.

protocol, so try to model this. However there is no point in implementing

This patch:
- moves decision to designate BSP from board into cpu, making cpu
self-sufficient in this regard. Later it will allow to cleanup hw/pc.c
and remove cpu_reset and wrappers from there.
- stores flag that CPU is BSP in IA32_APIC_BASE to model behavior

- uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP

According to the Intel manual
"Intel® 64 and IA-32 Architectures Software Developer’s Manual
Volume 3", "3.4.4 Segment Loading Instructions in IA-32e Mode":
"When in compatibility mode, FS and GS overrides operate as defined by
32-bit mode behavior regardless of the value loaded into the upper 32
linear-address bits of the hidden descriptor register base field.
Compatibility mode ignores the upper 32 bits when calculating an effective address."
However, the code misses the 64-bit mode case, where an instruction with
address and segment size override would be translated incorrectly. For example,
inc dword ptr gs:260h[ebx*4] gets incorrectly translated to:
(uint32_t)(gs.base + ebx * 4 + 0x260)
instead of
gs.base + (uint32_t)(ebx * 4 + 0x260)

KVM performs TPR raising asynchronously to QEMU, specifically outside
QEMU's global lock. When an interrupt is injected into the APIC and TPR
is checked to decide if this can be delivered, a stale TPR value may be
used, causing spurious interrupts in the end.
Fix this by deferring apic_update_irq to the context of the target VCPU.
We introduce a new interrupt flag for this, CPU_INTERRUPT_POLL. When it
is set, the VCPU calls apic_poll_irq before checking for further pending
interrupts. To avoid special-casing KVM, we also implement this logic
for TCG mode.

was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()
that would operate on QOM objects.
All callers have been updated except for one in target-mips, so drop all
implementations except for the one in target-mips and move the
declaration there until MIPSCPU reset can be fully QOM'ified.

We should know where the note and memory is stored before writing
them to vmcore. If we know this, we can avoid using lseek() when
creating vmcore.

Dump info contains: endian, class and architecture. The next
patch will use these information to create vmcore. Note: on
x86 box, the class is ELFCLASS64 if the memory is larger than 4G.
