Turns out we over-engineered Direct Mode for stimers a bit: unlike traditional stimers where we may want to try to re-inject the message upon EOI, Direct Mode stimers just set the irq in APIC and kvm_apic_set_irq() fails only when APIC is disabled (see APIC_DM_FIXED case in __apic_accept_irq()). Remove the redundant part. Suggested-by: Roman Kagan <rkagan@virtuozzo.com> Signed-off-by: Vitaly Kuznetsov <vkuznets@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.
