target-i386: Convert 'check' and 'enforce' to static properties

  • Additionally convert check_cpuid & enforce_cpuid to bool and make them
    members of X86CPU
  • Make 'enforce' feature independent from 'check'

target-i386: forward CPUID cache leaves when -cpu host is used

Some users running cpu intensive tasks checking the cache CPUID leaves at
startup and making decisions based on the result reported that the guest was
not reflecting the host CPUID leaves when -cpu host is used....

target-i386: Move hyperv_* static globals to X86CPU

- since hyperv_* helper functions are used only in target-i386/kvm.c
move them there as static helpers

target-i386: Disable PMU CPUID leaf by default

Bug description: QEMU currently gets all bits from GET_SUPPORTED_CPUID
for CPUID leaf 0xA and passes them directly to the guest. This makes
the guest ABI depend on host kernel and host CPU capabilities, and
breaks live migration if we migrate between hosts with different...

cpu: Turn cpu_get_phys_page_debug() into a CPUClass hook

Change breakpoint_invalidate() argument to CPUState alongside.

Since all targets now assign a softmmu-only field, we can drop helpers

cpu: Drop unnecessary dynamic casts in *_env_get_cpu()

A transition from CPUFooState to FooCPU can be considered safe,
just like FooCPU::env access in the opposite direction.
The only benefit of the FOO_CPU() casts would be protection against
bogus CPUFooState pointers, but then surrounding code would likely...

cpu: Turn cpu_dump_{state,statistics}() into CPUState hooks

Make cpustats monitor command available unconditionally.

Prepares for changing kvm_handle_internal_error() and kvm_cpu_exec()
arguments to CPUState.

cpu: Replace do_interrupt() by CPUClass::do_interrupt method

This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU...

DeviceClass::realize and set realized = true in cpu_x86_init().

The QOM realizefn cannot depend on errp being non-NULL as in

target-i386: QOM'ify CPU

Embed CPUX86State as first member of X86CPU.
Distinguish between "x86_64-cpu" and "i386-cpu".
Drop cpu_x86_close() in favor of calling object_delete() directly.

For now let CPUClass::reset() call cpu_state_reset().
