[Xen-devel] [PATCH] linux: do_callback_op()''s second argument can be const
Subject: Constify pointer argument of HYPERVISOR_callback_op
This (obviously) duplicates the public header changes already submitted
with the Xen side patch.
As usual, written and tested on 2.6.24-rc7 and made apply to the 2.6.18
tree without further testing.
