Pull x86/apic update from Thomas Gleixner: "A single commit which reduces cache misses in __x2apic_send_IPI_mask() significantly by converting x86_cpu_to_logical_apicid() to an array instead of using per CPU storage. This reduces the cost for a full broadcast on a dual socket system with 256 CPUs from 33 down to 11 microseconds" * tag 'x86-apic-2021-11-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/apic: Reduce cache line misses in __x2apic_send_IPI_mask()
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.
