xen: fix "xen: implement save/restore"
-tip testing found the following build breakage: drivers/built-in.o: In function `xen_suspend': manage.c:(.text+0x4390f): undefined reference to `xen_console_resume' with this config: http://redhat.com/~mingo/misc/config-Thu_May_29_09_23_16_CEST_2008.bad i have bisected it down to: | commit 0e91398f2a5d4eb6b07df8115917d0d1cf3e9b58 | Author: Jeremy Fitzhardinge <jeremy@goop.org> | Date: Mon May 26 23:31:27 2008 +0100 | | xen: implement save/restore the problem is that drivers/xen/manage.c is built unconditionally if CONFIG_XEN is enabled and makes use of xen_suspend(), but drivers/char/hvc_xen.c, where the xen_suspend() method is implemented, is only build if CONFIG_HVC_XEN=y as well. i have solved this by providing a NOP implementation for xen_suspend() in the !CONFIG_HVC_XEN case.
