[PATCH v2 00/24] dynamic-debug cleanups refactors maintenance + alignment fix

[Jim Cromie <jim.cromie@gmail.com>]

This series primarily revises:
 https://lore.kernel.org/lkml/20260504-dd-cleanups-2-v1-0-6fdd24040642@gmail.com/
    
rev2 addresses all of sashiko's feedback:
 https://sashiko.dev/#/patchset/20260504-dd-cleanups-2-v1-0-6fdd24040642%40gmail.com
    
I dropped the pr-fmt patch as not reproducible,
advanced the drop-NAMES patch to reduce subsequent churn,
and fixed the classmaps PARAMs to u64 to avoid 32bit flags on 32bit arches
    
For easy one-stop-shopping, it also includes 2 smaller series:
    
1st fixes a section alignment problem, with Reviewed-by from Petr Pavlu
 https://lore.kernel.org/lkml/20260515-asm-generic-1-v3-0-680b273666d4@gmail.com/
    
2nd is 2 doc-only patches for current behavior, not drawing any comments:
 https://lore.kernel.org/linux-doc/20260502-dyndbg-doc-v1-0-67cc4a93a77e@gmail.com/
    
Not included here is the API fix for classmaps, which splits
DECLARE_DYNDBG_CLASSES into DYNAMIC_DEBUG_CLASSMAP{_DEFINE,_USE}, and
the changes to drivers/gpu/drm/* to use the repaired api.
I'll schedule that flight after this one lands.
