Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
4db61fef16
In an effort to clarify and simplify the annotation of assembly functions in the kernel new macros have been introduced. These replace ENTRY and ENDPROC with separate annotations for standard C callable functions, data and code with different calling conventions. Using these for __smccc_workaround_1_smc is more involved than for most symbols as this symbol is annotated quite unusually, rather than just have the explicit symbol we define _start and _end symbols which we then use to compute the length. This does not play at all nicely with the new style macros. Instead define a constant for the size of the function and use that in both the C code and for .org based size checks in the assembly code.

README
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.
