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.
