The macros __seq_to_nbcon_seq() and __nbcon_seq_to_seq() are used to provide support for atomic handling of sequence numbers on 32bit systems. Until now this was only used by nbcon.c, which is why they were located in nbcon.c and include nbcon in the name. In a follow-up commit this functionality is also needed by printk_ringbuffer. Rather than duplicating the functionality, relocate the macros to printk_ringbuffer.h. Also, since the macros will be no longer nbcon-specific, rename them to __u64seq_to_ulseq() and __ulseq_to_u64seq(). This does not result in any functional change.

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.
