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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.

Greg reported that commit 3c241210 ("ARM: 8756/1: NOMMU: Postpone MPU activation till __after_proc_init") is causing breakage for the old Versatile platform in no-MMU mode (with out-of-tree patches): AS arch/arm/kernel/head-nommu.o arch/arm/kernel/head-nommu.S: Assembler messages: arch/arm/kernel/head-nommu.S:180: Error: selected processor does not support `isb' in ARM mode scripts/Makefile.build:417: recipe for target 'arch/arm/kernel/head-nommu.o' failed make[2]: *** [arch/arm/kernel/head-nommu.o] Error 1 Makefile:1034: recipe for target 'arch/arm/kernel' failed make[1]: *** [arch/arm/kernel] Error 2 Since the code is common for all NOMMU builds usage of the isb was a bad idea (please, note that isb also used in MPU related code which is fine because MPU has dependency on CPU_V7/CPU_V7M), instead use more robust instr_sync assembler macro.
