The first patch fixes Xen PV regression introduced by 32-bit rewrite. Unlike the earlier version it uses ALTERNATIVE instruction and avoids using xen_sysexit (and sysret32 in compat mode) pv ops, as suggested by Andy. (I ended up patching TEST with XOR to avoid extra NOPs, even though I said yesterday it would be wrong. It's not wrong) As result of this patch irq_enable_sysexit and

Hi folks, Here is the result of the latest work on the pvops front, after the x86 arch merge. From the functionality point of view, almost nothing was changed, except for proper vsmp support - which was discussed, but not implemented before - and the introduction of smp_ops in x86_64, which eased the merging of the smp header. Speaking of the merge, a significant part (although not majority) of

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
