The different architectures used their own (and different) declarations:
extern __visible const void __nosave_begin, __nosave_end;
extern const void __nosave_begin, __nosave_end;
extern long __nosave_begin, __nosave_end;
Consolidate them using the first variant in <asm/sections.h>.

* may be out of this range on some architectures.

* [_sinittext, _einittext]: contains .init.text.* sections
|

* [__bss_start, __bss_stop]: contains BSS sections
