For arm32, we get the following build warning:
In file included from /tmp/next/build/include/linux/printk.h:10,
from /tmp/next/build/include/linux/kernel.h:31,
from /tmp/next/build/block/blk-settings.c:5:
/tmp/next/build/block/blk-settings.c: In function 'blk_validate_atomic_write_limits':
/tmp/next/build/include/asm-generic/div64.h:222:35: warning: comparison of distinct pointer types lacks a cast
222 | (void)(((typeof((n)) *)0) == ((uint64_t *)0)); \
| ^~
The divident for do_div() should be 64b, which it is not. Since we want to
check 2x unsigned ints, just use % operator. This allows us to drop the
chunk_sectors variable.
Fixes: 9da3d1e912f3 ("block: Add core atomic write support")

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 reStructuredText 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.
