Subject: [PATCH 0/7] x86/boot: Shrink the decompression stub: conditionally exclude cmdline processing

This is a patch set that progressively allows more of the decompression command
line processing code to be removed if it can't be used.  This can shrink the
compressed kernel image by over 2k.  The quiet and debug flags been switched to
use the pre-existing CONFIG_X86_VERBOSE_BOOT compile flag instead.  And when
not compiled with earlyprintk debugging, the command-line processing code now
has nothing to configure, so exclude it entirely.

Gokul Caushik (1):
  x86/boot: Exclude cmdline.c if you can't use it

Joe Millenbach (6):
  x86/boot: Removed quiet flag and switched quiet output to debug flag
  x86/boot: Wrap debug printing in a new debug_putstr function
  x86/boot: Changed error putstr path to match new debug_putstr format
  x86/boot: Switch output functions from command-line flags to
    conditional compilation
  x86/boot: Removed unused debug flag and set code
  x86/boot: Exclude early_serial_console.c if can't use it.
