cover adjust pvops to accomodate its x86_64 variant

Hi folks,

With this series, the bulk of the work of pvops64 is done. Here, I integrate most of the paravirt.c and paravirt.h files, making them applicable to both architectures.

CONFIG_PARAVIRT is _not_ present yet. Basically, this code is missing page table integration (patches currently being worked on by Jeremy).

Enjoy

PATCH 1/15 change paravirt_32.c name

This patch changes paravirt_32.c to paravirt.c. The goal is to have paravirt support in x86_64, so we do it in a common file

PATCH 2/15 adjust PVOP_CALL/VCALL macros for x86_64

This patch adjust the PVOP_VCALL and PVOP_CALL macros to work with x86_64. It has a different calling convention, and we use auxiliary macros to account for both calling conventions as cleanly as possible

Comments are adjusted accordingly.

PATCH 5/15 change assembly definition of paravirt_patch_site

To account for differences in x86_64, we change the macros that create raw instances of the paravirt_patch_site struct.
We need to align 64-pointers to 64-bit boundaries, so we add an alignment directive. Also, we need to make room for a word-sized pointer, instead of a fixed 32-bit one

PATCH 10/15 replace privileged instructions with paravirt macros

The assembly code in entry_64.S issues a bunch of privileged instructions, like cli, sti, swapgs, and others. Paravirt guests are forbidden to do so, and we then replace them with macros that will do the right thing.

PATCH 12/15 add CLBR_ defines for x86_64.

x86_64 needs a potentially larger clobber list than i386, due to its calling convention. So we add more CLBR_ defines for it.
Note that CLBR_ANY is different for each of the architectures, since it comprises the notion of "All call clobbers in this architecture"

Re: [PATCH 13/15] move patching code to arch-specific file.

Quoted 11 lines · Ingo Molnar

this patch adds the paravirt_patch_32.o:

Subject: [PATCH] [PATCH] move patching code to arch-specific file.
