Hoist the CPU => APIC ID conversion for the Posted Interrupt descriptor out of the loop to write the descriptor, preemption is disabled so the CPU won't change, and if the APIC ID changes KVM has bigger problems. No functional change intended. Signed-off-by: Sean Christopherson <seanjc@google.com> Message-Id: <20211009021236.4122790-28-seanjc@google.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.
