That's a forward port of the core HAX interface code from the
emu-2.2-release branch in the external/qemu-android repository as used by
the Android emulator.
The original commit was "target/i386: Add Intel HAX to android emulator"
saying:
"""
Backport of 2b3098ff27bab079caab9b46b58546b5036f5c0c
from studio-1.4-dev into emu-master-dev
Intel HAX (harware acceleration) will enhance android emulator performance
in Windows and Mac OS X in the systems powered by Intel processors with
"Intel Hardware Accelerated Execution Manager" package installed when
user runs android emulator with Intel target.

It has been modified to build and run along with the current code base.
The formatting has been fixed to go through scripts/checkpatch.pl,
and the DPRINTF macros have been updated to get the instanciations checked by
the compiler.
The FPU registers saving/restoring has been updated to match the current
QEMU registers layout.
The implementation has been simplified by doing the following modifications:
- removing the code for supporting the hardware without Unrestricted Guest (UG)
mode (including all the code to fallback on TCG emulation).
- not including the Darwin support (which is not yet debugged/tested).
- simplifying the initialization by removing the leftovers from the Android
specific code, then trimming down the remaining logic.
- removing the unused MemoryListener callbacks.

rcu_read_unlock was not called if the address_space_access_valid result is

This caused (at least) a problem when qemu on PPC/E500+TAP failed to terminate

Split irqchip works based on the fact that we kept the first 24 gsi
routing entries inside KVM for userspace ioapic's use. When system
boot, we'll reserve these MSI routing entries before hand. However,
after migration, we forgot to re-configure it up in the destination
side. The result is, we'll get invalid gsi routing entries after
migration (all empty), and we get interrupts with vector=0, then
strange things happen, like keyboard hang.
The solution is simple - we update them after migration, which is a
one line fix.

'hotplugged' propperty is meant to be used on migration side when migrating
source with hotplugged devices.
However though it not exacly correct usage of 'hotplugged' property
it's possible to set generic hotplugged property for CPU using
-cpu foo,hotplugged=on
or
-global foo.hotplugged=on
in this case qemu crashes with following backtrace:
...
because pc_cpu_plug() assumes that hotplugged CPU could appear only after
rtc/fw_cfg are initialized.
Fix crash by replacing assumption with explicit checks of rtc/fw_cfg
and updating them only if they were initialized.
