Dou Liyang ca5d376e17 x86/paravirt: Set up the virt_spin_lock_key after static keys get initialized
Commit:

  9043442b43 ("locking/paravirt: Use new static key for controlling call of virt_spin_lock()")

sets the static virt_spin_lock_key to a value before jump_label_init()
has been called, which will result in a WARN().

Reorder the initialization sequence:

 - Move the native_pv_lock_init() into native_smp_prepare_cpus()
 - set the value in xen_init_lock_cpu()

to avoid calling into the not yet initialized static keys subsystem.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
