Hello Arthur Heymans, Julius Werner, Jérémy Compostella, Lean Sheng Tan, Martin L Roth, Patrick Rudolph, build bot (Jenkins),

I'd like you to reexamine a change. Please visit

to look at the new patch set (#5).

symbols: Add __maybe_unused flag to region variable symbols

In DECLARE_REGION and DECLARE_OPTIONAL_REGION, a set of 3 variables
will be defined, that is the region 'base', 'end' and 'size'.
However, in many codes, the users will only selectively use 'end'
or 'size' instead of both of them, which will trigger compiler errors
for unused variables. This patch sets __maybe_unused attributes on
'end' and 'size' so that users do not need to use all of them.
