* x86, xen, power: fix up config dependencies on PMJeremy Fitzhardinge2008-07-171-0/+5
| | | | | | | | | | 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.

| * | xen: remove support for non-PAE 32-bitJeremy Fitzhardinge2008-06-241-1/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | 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.

* | xen: add configurable max domain sizeJeremy Fitzhardinge2008-05-271-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* x86: remove depends on X86_32 from PARAVIRT & PARAVIRT_GUESTEduardo Pereira Habkost2008-01-301-0/+1
| | | | | | | | | | | | 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.

* Normalize config options for guest supportRusty Russell2007-10-231-2/+3
| | | | | | | | | | | | | 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.
