Group all the "guest OS" support options together, under CONFIG_PARAVIRT. Make this a proper menu item so it looks neater on menuconfig etc, and make the wording for each prompt uniform.

Introduce the basic VMI sub-arch configuration dependencies. VMI kernels only are designed to run on modern hardware platforms. As such, they require a working APIC, and do not support some legacy functionality, including APM BIOS, ISA and MCA bus systems, PCI BIOS interfaces, or PnP BIOS (by implication of dropping ISA support). They also require a P6 series CPU. Signed-off-by: Zachary Amsden

(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.

This version over last version: (1) Gets rid of the no_paravirt.h header and leaves native ops in place (with some reshuffling to keep then under one #ifdef). (2) Fixes the "X crashes with CONFIG_PARAVIRT=y" bug. (3) Puts __ex_table entry in paravirt iret. Another followup patch implements binary patching...

Create a configurable hole in the linear address space at the top of memory. A more advanced interface is needed to negotiate how much space the hypervisor is allowed to steal, but in the end, it seems most likely that a fixed constant size will be chosen for the compiled kernel, potentially propagated to an information page used by paravirtual initialization to determine interface compatibility.

OK, this is the revised paravirt.h (Andi has seen this before), then the second is the binary patching stuff. More things get added to the paravirt struct in future patches, but this basic stuff hasn't changed for some time. ==== This patch does the dumbest possible replacement of paravirtualized instructions: calls through a "paravirt_ops" structure. Currently these are function

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.

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.

The following patches introduce the core infrastructure needed to paravirtualize the 32-bit x86 Linux kernel. This is done by moving virtualization sensitive insn's or code paths to a function table, paravirt_ops. This structure can be populated with hypervisor specific calls or native stubs and currently support running on bare metal, VMI, Xen, or Lhype. These patches apply to
