Linux kernel source tree
680e7863de
With CM 3.5 the "core-other" register block evolves into the "redirect" register block, which is capable of accessing not only the core local registers of other cores but also the shared/global registers of other clusters. This patch generates accessor functions for shared/global registers accessed via the redirect block, with "redir_" inserted after "gic_" in their names. For example the accessor function: read_gic_config() ...accesses the GIC_CONFIG register of the GIC in the local cluster. With this patch a new function: read_gic_redir_config() ...is added which accesses the GIC_CONFIG register of the GIC in whichever cluster the GCR_CL_REDIRECT register is configured to access. This mirrors the similar redirect block accessors already provided for the CM & CPC.

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.
