Commit f4e61f0c9a ("x86/kvm: Fix broken irq restoration in kvm_wait")
replaced "local_irq_restore() when IRQ enabled" with "local_irq_enable()
when IRQ enabled" to suppress a warnning.
Although there is no similar debugging warnning for doing local_irq_enable()
when IRQ enabled as doing local_irq_restore() in the same IRQ situation. But
doing local_irq_enable() when IRQ enabled is no less broken as doing
local_irq_restore() and we'd better avoid it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
