- Fix KVM "lost kick" race, where an attempt to pull a vcpu out of the guest could be
lost (or delayed until the next guest exit).
- Disable SCV (system call vectored) when PR KVM guests could be run.
- Fix KVM PR guests using SCV, by disallowing AIL != 0 for KVM PR guests.
- Add a new KVM CAP to indicate if AIL == 3 is supported.
- Fix a regression when hotplugging a CPU to a memoryless/cpuless node.
- Make virt_addr_valid() stricter for 64-bit Book3E & 32-bit, which fixes crashes seen
due to hardened usercopy.
- Revert a change to max_mapnr which broke HIGHMEM.
Thanks to: Christophe Leroy, Fabiano Rosas, Kefeng Wang, Nicholas Piggin, Srikar Dronamraju.

README
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.
