This patch replaces the (1 << n) with BIT(n) and cleans up whitespace,
no functional change.

This compiles just fine without it though, which means it's probably
pulled in through some of the other includes already present.

I suspected that. However, please see rule #1 in
Documentation/process/submit-checklist.rst:

1) If you use a facility then #include the file that defines/declares
   that facility.  Don't depend on other header files pulling in ones
   that you use.

If I was to include every single header from which I use something,
wouldn't that make the list real long then ? Is that really worth it?

Hi Marek,

Thanks for your work.

I like this cleanup! I have no input on Randy's comment about if you 
should include bitops.h or not. But for the macro changes themselves.

The length of the list of headers is not an issue.
And if you are "cleaning up," you might as well do a full job of it.

Just because it builds on one $ARCH (with various pulled-in headers) does
not mean that it will build on another $ARCH (with different pulled-in headers).

Or did you build it on all linux/arch/* ?

I sent a V3 of this "clean up".

No, since it is limited in Kconfig:
        depends on ARCH_RENESAS || (ARM && COMPILE_TEST)
