Current Skylake-Server, Cascadelake-Server and Icelake-Server CPU models
lack several VMX features. Icelake-Server also lacks two features in
FEAT_7_0_EBX. In addition, The model numbers of Icelake-Client and
Icelake-Server need to be fixed.

Public bug reported:
I have a bootable image where GNOME Shell fails because it hits a limit
in virtio-gpu.
In `hw/display/virtio-gpu.c`, there is a limit for `nr_entries` at
16384. There is no explanation for that limit. But there does not seem
to be any limit on the kernel side.

There is a special quiesce PSW that we check for "shutdown". Otherwise disabled
wait is detected as "crashed". Architecturally we must only check PSW bits
116-127. Fix this.

RNSBG is handled via the op_rosbg() helper function. But RNSBG has
the opcode 0xEC54, i.e. 0x54 as second byte, while op_rosbg() currently
checks for 0x55. This seems to be a typo, fix it to use 0x54 instead,
so that op_rosbg() does not abort() anymore if a program uses RNSBG.
Move to system/, as this is mostly about configuring vfio-ap.

I totally disagree with your using the term "hardfloat feature enabled" in

Factor it out and properly use it where applicable. Make
qemu_vfio_undo_mapping() look like qemu_vfio_do_mapping(), passing the
size and iova, not the mapping.

Everybody discards the error. Let's error_report() instead so this error
doesn't get lost.
This is now the same error handling as in qemu_vfio_do_mapping(). However,
we don't report any errors via the return value to the caller. This seems
to be one of these "will never happen, but let's better
I don't see why we shouldn't apply all settings to make it look like the
surrounding RAM (and enable proper VMA merging).
Note: memory backend settings might have overridden these settings. We
would need a callback to let the memory backend fix that up.

We want to actually use resizeable allocations in resizeable ram blocks
(IOW, make everything between used_length and max_length inaccessible) -
however, not all ram block notifiers can support that.
Introduce a way to detect if any registered notifier does not
support resizes -
Introduce qemu_anon_ram_alloc_resizeable() and qemu_anon_ram_resize().
Implement them under POSIX and make them return NULL under WIN32.
Under POSIX, we make use of resizeable mmaps. An implementation under
WIN32 is theoretically possible AFAIK and can be added later.
In qemu_anon_ram_free(),
