Seongsu Park cf938f9178 arm64: Cleanup __cpu_set_tcr_t0sz()
The T0SZ field of TCR_EL1 occupies bits 0-5 of the register and encode
the virtual address space translated by TTBR0_EL1. When updating the
field, for example because we are switching to/from the idmap page-table,
__cpu_set_tcr_t0sz() erroneously treats its 't0sz' argument as unshifted,
resulting in harmless but confusing double shifts by 0 in the code.

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.
