This series primarily revises: https://lore.kernel.org/lkml/[email protected]/ 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/[email protected]/ 2nd is 2 doc-only patches for current behavior, not drawing any comments: https://lore.kernel.org/linux-doc/[email protected]/ 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. Signed-off-by: Jim Cromie <[email protected]>
