Will Deacon 7ed3cce2fe arm64: mm: Drop 'const' from conditional arm64_dma_phys_limit definition 
commit 770093459b upstream.

Commit 031495635b ("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.

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.
