Suravee Suthikulpanit 4cbb69b45c KVM: x86: Fixes posted interrupt check for IRQs delivery modes 
commit 637543a8d6 upstream.

Current logic incorrectly uses the enum ioapic_irq_destination_types
to check the posted interrupt destination types. However, the value was
set using APIC_DM_XXX macros, which are left-shifted by 8 bits.

Fixes by using the APIC_DM_FIXED and APIC_DM_LOWEST instead.

Fixes: (fdcf756213 'KVM: x86: Disable posted interrupts for non-standard IRQs delivery modes')

README 

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.
