[PATCH] x86/paravirt: hide unused patch_default label
A bugfix introduced a harmless warning:
arch/x86/kernel/paravirt_patch_32.c: In function 'native_patch':
arch/x86/kernel/paravirt_patch_32.c:71:1: error: label 'patch_default' defined but not used [-Werror=unused-label]
This puts it in the same #ifdef as its caller.
Fixes: 45dbea5f55c0 ("x86/paravirt: Fix native_patch()")

[PATCH 0/4] make virt_spin_lock() a pvops function
With virt_spin_lock() being a pvops function the bare metal case can be
optimized by patching the call away completely. In case a kernel running
as a guest it can decide whether to use paravitualized spinlocks, the
current fallback to the unfair test-and-set scheme, or to mimic the
bare metal behavior.

[PATCH 00/13] x86/paravirt: Make pv ops code generation more closely match reality
This changes the pv ops code generation to more closely match reality.
For example, instead of:
callq *0xffffffff81e3a400 (pv_irq_ops.save_fl)
vmlinux will now show:
pushfq
pop %rax
nop
nop
nop
nop
nop
which is what the runtime version of the code will show in most cases.
This idea was suggested by Andy Lutomirski.
The benefits are:

[PATCH 00/10] paravirt: make amount of paravirtualization configurable
Today paravirtualization is a all-or-nothing game: either a kernel is
compiled with no paravirtualization support at all, or it is supporting
paravirtualized environments like Xen pv-guests or lguest additionally
to some paravirtualized tuning for KVM, Hyperv, VMWare or Xen
HVM-guests.
As support of pv-guests requires quite intrusive pv-hooks (e.g. all
access functions to page table entries,
