Kernel for Galaxy S24, rebased on CLO sources (WIP)
8a2b456665
It is permissible for kernel code to call virt_to_phys() against virtual
addresses that are in KSEG0 or KSEG1 and we need to be dealing with both
types. Rewrite the test condition to ensure that the kernel virtual
addresses are above PAGE_OFFSET which they must be, and below KSEG2
where the non-linear mapping starts.
For EVA, there is not much that we can do given the linear address range
that is offered, so just return any virtual address as being valid.
Finally, when HIGHMEM is not enabled, all virtual addresses are assumed
to be valid as well.

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.
