We were using either APIC_DEST_PHYSICAL|APIC_DEST_LOGICAL or 0|1 to fill in kvm_lapic_irq.dest_mode. It's fine only because in most cases when we check against dest_mode it's against APIC_DEST_PHYSICAL (which equals to 0). However, that's not consistent. We'll have problem when we want to start checking against APIC_DEST_LOGICAL, which does not equals to 1. This patch firstly introduces kvm_lapic_irq_dest_mode() helper to take any boolean of destination mode and return the APIC_DEST_* macro. Then, it replaces the 0|1 settings of irq.dest_mode with the helper. Signed-off-by: Peter Xu <peterx@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
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.
