You probably need to rename the driver.

The iret paravirt op is rather special as it is using a jmp instead
of a call instruction. Switch it to ALTERNATIVE.

Instead of patching an ud2 instruction for unpopulated vector entries

This is a major cleanup of the paravirt infrastructure aiming at
eliminating all custom code patching via paravirt patching.
This is achieved by using ALTERNATIVE instead, leading to the ability
to give objtool access to the patched in instructions.
In order to remove most of the 32-bit special
There is no need any longer to have different paravirt patch functions
for native and Xen. Eliminate native_patch() and rename
paravirt_patch_default() to paravirt_patch().

For being able to switch paravirt patching from special cased custom
code sequences to ALTERNATIVE handling some X86_FEATURE_* are needed
as new features. This enables to have the standard indirect pv call
as the default code and to patch that with the non-Xen custom code
sequence via ALTERNATIVE
PVOP_VCALL4() is only used for Xen PV, while PVOP_CALL4() isn't used
at all. Keep PVOP_CALL4() for 64 bits due to symmetry reasons.
This allows to remove the 32-bit definitions of those macros leading
to a substantial simplification of the paravirt macros, as those were
the only ones needing
The time pvops functions are the only ones left which might be
used in 32-bit mode and which return a 64-bit value.
Switch them to use the static_call() mechanism instead of pvops, as
this allows quite some simplification of the pvops implementation.

The central pvops call macros PVOP_CALL() and PVOP_VCALL() are
looking very similar now.
The main differences are using PVOP_VCALL_ARGS or PVOP_CALL_ARGS, which
are identical, and the return value handling.
So drop PVOP_VCALL_ARGS and instead of PVOP_VCALL() just use
