Commit031495635b("arm64: Do not defer reserve_crashkernel() for platforms with no DMA memory zones") introduced different definitions for 'arm64_dma_phys_limit' depending on CONFIG_ZONE_DMA{,32} based on a late suggestion from Pasha. Sadly, this results in a build error when passing W=1: | arch/arm64/mm/init.c:90:19: error: conflicting type qualifiers for 'arm64_dma_phys_limit' Drop the 'const' for now and use '__ro_after_init' consistently.

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.
