Subject: xen/arm: Fix compile errors when drivers are compiled as modules.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=911dec0db4de6ccc544178a8ddaf9cec0a11d533;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

xen/arm: Fix compile errors when drivers are compiled as modules.

We end up with:

ERROR: "HYPERVISOR_event_channel_op" [drivers/xen/xen-gntdev.ko] undefined!
ERROR: "privcmd_call" [drivers/xen/xen-privcmd.ko] undefined!
ERROR: "HYPERVISOR_grant_table_op" [drivers/net/xen-netback/xen-netback.ko] undefined!

and this patch exports said function (which is implemented in hypercall.S).
