similar to: [PATCH 1/3] Normalize config options for guest support

(Unless there are complaints, I'll push this as part of the lguest patches for 2.6.24, since there are lguest config changes there too). Andi points out that PARAVIRT is an option best selected when needed. We introduce PARAVIRT_GUEST for the menu itself, and select PARAVIRT if the user turns on anything which needs it.

The TSC register is a requirement when running under Xen, but that's going to be present on any CPU which can boot Xen. We don't need any of the kernel's TSC machinery, since the usage is contained within the Xen interfaces, and therefore XEN does not need to depend on CONFIG_X86_TSC.

Hi Rusty, Lguest should depend on BLOCK too , without BLOCK set I get this error: ... drivers/block/lguest_blk.c: In function 'end_entire_request': drivers/block/lguest_blk.c:80: error: implicit declaration of function 'end_that_request_first' drivers/block/lguest_blk.c:80: error: dereferencing pointer to incomplete type drivers/block/lguest_blk.c:82: error: implicit declaration

This seems to have been added in f0f32fccbffa to avoid a conflict arising from the long deceased ARCH_SETUP() macro and subsequently pushed down to the XEN option. As far as I can tell the conflict is no longer present and by dropping the dependency I was able to build a kernel which has both CONFIG_XEN and CONFIG_X86_VISWS enabled and boot it on Xen. I didn't try it on the VISWS platform.

The ARM platform has no concept of PVMMU and therefor no HYPERVISOR_update_va_mapping et al. Allow this code to be compiled out when not required. In some similar situations (e.g. P2M) we have defined dummy functions to avoid this, however I think we can/should draw the line at dummying out actual hypercalls.

This series contain fixes to make the paravirt_ops code compile and boot on x86_64. This is a follow-up for the previous series from Glauber.

Lguest drivers need to default to "Y" otherwise they're never selected for new builds. (We don't bother prompting, because they're less than 4k combined, and implied by selecting lguest support).

Hi, this version requires that host and guest have the same PAE status. NX cap is not offered to the guest, yet.

Add a new config item PARAVIRT_FULL. It will be used to guard the pv_*_ops functions used by fully paravirtualized guests (Xen pv-guests and lguest) only. Kernels not meant to support those guest types will be able to use many operations without paravirt abstraction while still supporting all the other paravirt features. For now just add the new Kconfig option and select it for XEN_PV and

Andrew Morton commented out some stuff to make lguest compile. This should actually make it work (in the latest -mm).
