Add hyp percpu section to linker script and rename the corresponding ELF sections of hyp/nvhe object files. This moves all nVHE-specific percpu variables to the new hyp percpu section. Allocate sufficient amount of memory for all percpu hyp regions at global KVM init time and create corresponding hyp mappings. The base addresses of hyp percpu regions are kept in a dynamically allocated array in the kernel. Add NULL checks in PMU event-reset code as it may run before KVM memory is initialized.

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.
