linux-user: Implement new ARM 64 bit cmpxchg kernel helper
linux-user: Implement new ARM 64 bit cmpxchg kernel helper
Linux 3.1 will have a new kernel-page helper for ARM implementing
64 bit cmpxchg. Implement this helper in QEMU linux-user mode:
* Provide kernel helper emulation for 64bit cmpxchg
* Allow guest to object to guest offset to ensure it can map a page
* Populate page with kernel helper version
