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.

There's no real reason we can't support sparsemem/discontigmem, so do so. This is mostly useful to support hotplug memory. Signed-off-by: NJeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: NIngo Molnar <mingo@elte.hu> Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

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.

Add Xen support for preemption. This is mostly a cleanup of existing preempt_enable/disable calls, or just comments to explain the current usage. Signed-off-by: NJeremy Fitzhardinge <jeremy@xensource.com> Signed-off-by: NChris Wright <chrisw@sous-sol.org>

This is a fairly straightforward Xen implementation of smp_ops. Xen has its own IPI mechanisms, and has no dependency on any APIC-based IPI. The smp_ops hooks and the flush_tlb_others pv_op allow a Xen guest to avoid all APIC code in arch/i386 (the only apic operation is a single apic_read for the apic version number). One subtle point which needs to be addressed is unpinning pagetables when another cpu may have a lazy tlb reference to the pagetable. Xen will not allow an in-use pagetable to be unpinned, so we must find any other cpus with a reference to the pagetable and get them to shoot down their references.
