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.

Add support for exporting statistics on mmu updates, multicall
batching and pv spinlocks into debugfs. The base path is xen/ and
each subsystem adds its own directory: mmu, multicalls, spinlocks.
In each directory, writing 1 to "zero_stats" will cause the
corresponding stats to be zeroed the next time they're updated.

Xen save/restore needs bits of code enabled by PM_SLEEP, and PM_SLEEP
depends on PM. So make XEN_SAVE_RESTORE depend on PM and PM_SLEEP
depend on XEN_SAVE_RESTORE.

Allow Xen to be enabled on 64-bit.
Also extend domain size limit from 8 GB (on 32-bit) to 32 GB on 64-bit.

Non-PAE operation has been deprecated in Xen for a while, and is
rarely tested or used. xen-unstable has now officially dropped
non-PAE support. Since Xen/pvops' non-PAE support has also been
broken for a while, we may as well completely drop it altogether.

Add a config option to set the max size of a Xen domain. This is used
to scale the size of the physical-to-machine array; it ends up using
around 1 page/GByte, so there's no reason to be very restrictive.
For a 32-bit guest, the default value of 8GB is probably sufficient;
there's not much point in giving a 32-bit machine much more memory
than that.

There's no real reason we can't support sparsemem/discontigmem, so do so.
This is mostly useful to support hotplug memory.

With this, the paravirt_ops code can be enabled on x86_64 also.
Each guest implementation (Xen, VMI, lguest) now depends on X86_32. The
dependencies can be dropped for each one when they start to support
x86_64.

1) Group all the "guest OS" support options together, under a PARAVIRT_GUEST
menu.
2) Make those options select CONFIG_PARAVIRT, as suggested by Andi.
3) Make kconfig help titles consistent.
