Could either of you clarify what the significance of such a construct
(encountered several times in arch/x86/Kconfig alone) is?
At first, I noticed it only with GENERIC_LOCKBREAK (it is my
understanding that this block can go away entirely), but then realized
that with the bool->def_bool conversion this was introduced in various
other places (where "default n" was used before, which seems as
pointless a statement). Am I missing something?
I assume this is solely to document that x86 does
NOT use GENERIC_LOCKBREAK as it serves no other purpose.
Notice that we may see:
And this will result in setting FOO to the last seen value.
All the HAVE_* stuff is btw to avoid such double definition
of a config symbol.
GENERIC_LOCKBREAK is another candidate.
