Chuck Ebbert 08115ab4d9 xen: make CONFIG_XEN_SAVE_RESTORE depend on CONFIG_XEN
Xen options need to depend on XEN.
Also, add newline at end of file.

Without this patch you need to disable CONFIG_PM in order to
disable CPU hotplugging.

help
This is the Linux Xen port. Enabling this will allow the
kernel to boot in a paravirtualized environment under the
Xen hypervisor.
config XEN_MAX_DOMAIN_MEMORY
int "Maximum allowed size of a domain in gigabytes"
default 8 if X86_32
default 32 if X86_64
depends on XEN
help
The pseudo-physical to machine address array is sized
according to the maximum possible memory size of a Xen
domain. This array uses 1 page per gigabyte, so there's no
need to be too stingy here.
config XEN_SAVE_RESTORE
bool
depends on XEN && PM
default y
config XEN_DEBUG_FS
bool "Enable Xen debug and tuning parameters in debugfs"
depends on XEN && DEBUG_FS
default n
help
Enable statistics output and various tuning options in debugfs.
Enabling this option may incur a significant performance overhead.
