[PATCH 0/4] cosmetic fixes to module pr_debugs

Hi Luis,

These 4 patches alter pr_debug() messages for more info, and less
log-spam.

* add "for $modname:" to banners
  helpful for finding one of many

[   40.885922] main:layout_sections: Core section allocation order for test_dynamic_debug:
    	       ~20 lines of output
[   40.885967] main:move_module: Final section addresses for test_dynamic_debug:
    	       ~2 lines - .init.text/data

* add symbol name to "Absolute symbol: <value>"
  val ~== 0 - less interesting than name

[   40.886006] main:simplify_symbols: Absolute symbol: 0x00000000 test_dynamic_debug.c
[   40.886008] main:simplify_symbols: Absolute symbol: 0x00000000 test_dynamic_debug.mod.c

* add size to section report. gives more info.

[   40.885968] main:move_module: 	0xffffffffc0249000 0x0000035d .text
[   40.885971] main:move_module: 	0xffffffffc0252000 0x0000003c .init.text

* drop already_uses: pr_debug("$ uses $b!") messages

  echo module main +pmf >/proc/dynamic_debug/control
  modprobe i915

before:
  dmesg | grep already_uses | cut -c15- | wc
    673    2722   28641
  dmesg | grep already_uses | cut -c15- | sort -u | wc
     26     134    1237

after:
  dmesg | grep already_uses | cut -c15- | wc
     15      90     756
  dmesg | grep already_uses | cut -c15- | sort -u | wc
     15      90     756


Jim Cromie (4):
  module: in layout_sections, move_module: add the modname
  module: add symbol-name to pr_debug Absolute symbol
  module: add section-size to move_module pr_debug
  module: already_uses() - reduce pr_debug output volume
