[Xen-devel] [PATCH 3/4] drivers: xen: Move prototype declaration to appropriate header file from arch/x86/xen/xen-ops.h

[Rashika Kheria <rashika.kheria@xxxxxxxxx>]

Move prototype declaration to header file include/xen/xen-ops.h from
arch/x86/xen/xen-ops.h because they are used by more than one file.

This eliminates the following warning in drivers/xen/events/:
drivers/xen/events_2l.c:1231:13: warning: no previous prototype for 
âxen_debug_interruptâ [-Wmissing-prototypes]
