In order to deal with the few AArch32 system registers that map to only a particular half of their AArch64 counterpart (such as DFAR and IFAR being colocated in FAR_EL1), let's add an optional annotation to the sysreg descriptor structure, indicating whether a register maps to the upper or lower 32bits of a register. Nothing is using these annotation yet. Signed-off-by: Marc Zyngier <maz@kernel.org>
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.
