Subject: xen-access: Correct default value of write-to-CR4 switch
X-Git-Tag: archive/raspbian/4.11.1-1+rpi1~1^2~66^2~1514
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=f975068fea81adc81b71864c70f9413521ef3a04;p=xen.git

xen-access: Correct default value of write-to-CR4 switch

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.
