A comment in the disable_step_tsk macro refers to synchronising with enable_dbg, as historically the entry used enable_dbg to unmask debug exceptions after disabling single-stepping. These days the unmasking happens in entry-common.c via local_daif_restore() or local_daif_inherit(), so the comment is stale. This logic is likely to chang in future, so it would be best to avoid referring to those macros specifically. Update the comment to take this into account, and describe it in terms of clearing DAIF.D so that it doesn't macro where this logic lives nor what it is called. There should be no functional change as a result of this patch.

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.
