Subject: xen: events: mark cpu_evtchn_mask_p as __refdata
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b052181a985592f81767f631f9f42accb4b436cd;p=deliverable%2Flinux.git

xen: events: mark cpu_evtchn_mask_p as __refdata

This variable starts out pointing at init_evtchn_mask which is marked
__initdata but is set to point to a non-init data region in xen_init_IRQ
which is itself an __init function so this is safe.
