[PATCH 0/5] PATCH 0/6] dyndbg: fix i386 alignment and KEEP module sections

[Jim Cromie]

This series starts with a fix to a section misalignement on i386, and
follows with cleanups and refactoring for reuse.

When CONFIG_DRM_USE_DYNAMIC_DEBUG=Y (currently marked BROKEN) and
CONFIG_DRM=y, the __dyndbg_classes section gets a single
struct/record.  On i386 this is 28-bytes, breaking the required
ALIGN(8) on the following __dyndbg section.

This breaks dynamic_debug_init() with a NULL pointer dereference; the
section traversal logic encounters padding bytes instead of a valid
descriptor.

the series:

1. adds ALIGN(8) to the BOUNDED_SECTION_* macros

2. refactors BOUNDED_SECTION_* macros for later reuse

3. adds dyndbg.lds.S to KEEP sections in modules
   follows codetag.lds.h model

4. drops unused HEADERED_SECTION_* macros

5. removes redundant (after patch 1) ALIGN(8)s in vmlinux.lds.h

6. adds BOUNDED_SECTION_* _ALIGN variants,
   usea them in ORC_UNWIND_TABLE
