Subject: [PATCH v7 0/9] dyndbg: drm.debug adaptation

hi Greg, Dan, Jason, DRM-folk,

heres follow-up to V6:
  rebased on driver-core/driver-core-next for -v6 applied bits (thanks)
  rework drm_debug_enabled{_raw,_instrumented,} per Dan.

It excludes:
  nouveau parts (immature)
  tracefs parts (I missed --to=Steve on v6)
  split _ddebug_site and de-duplicate experiment (way unready)

IOW, its the remaining commits of V6 on which Dan gave his Reviewed-by.

If these are good to apply, I'll rebase and repost the rest separately.

These are also available at:
https://github.com/jimc/linux/releases/tag/dyndbg%2Fdd-drm-class-911

RFC:

DECLARE_DYNDBG_CLASSMAP's interface can be improved: class-names are
currently strings, like "DRM_UT_CORE", which must have corresponding
ENUM symbols defined.  It would be better to just pass DRM_UT_CORE,
etc, and stringify the va-args inside the macro while initializing
classnames member.  But how ?

Jim Cromie (9):
  drm_print: condense enum drm_debug_category
  drm: POC drm on dyndbg - use in core, 2 helpers, 3 drivers.
  drm_print: interpose drm_*dbg with forwarding macros
  drm_print: wrap drm_*_dbg in dyndbg descriptor factory macro
  drm-print.h: include dyndbg header
  drm-print: add drm_dbg_driver to improve namespace symmetry
  drm_print: optimize drm_debug_enabled for jump-label
  drm_print: prefer bare printk KERN_DEBUG on generic fn
  drm_print: add _ddebug descriptor to drm_*dbg prototypes
