[Xen-devel] [PATCH] xen-access: Correct default value of write-to-CR4 switch

[Sergej Proskurin <proskurin@xxxxxxxxxxxxx>]

The current implementation configures the test environment to always
trap on writes to the CR4 control register, even on ARM. This leads to
issues as calling xc_monitor_write_ctrlreg on ARM with VM_EVENT_X86_CR4
will always fail.
