* kvm-arm64/vgic-lr-overflow: (50 commits) : Support for VGIC LR overflows, courtesy of Marc Zyngier : : Address deficiencies in KVM's GIC emulation when a vCPU has more active : IRQs than can be represented in the VGIC list registers. Sort the AP : list to prioritize inactive and pending IRQs, potentially spilling : active IRQs outside of the LRs. : : Handle deactivation of IRQs outside of the LRs for both EOImode=0/1, : which involves special consideration for SPIs being deactivated from a : different vCPU than the one that acked it.

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 reStructuredText 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.
