Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild 

Pull kbuild changes from Michal Marek:
 - Unification of cmd_uimage among archs that use it
 - make headers_check tries harder before reporting a missing
   <linux/types.h> include
 - kbuild portability fix for shells that do not support echo -e
 - make clean descends into samples/
 - setlocalversion grep fix
 - modpost typo fix
 - dtc warnings fix

* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  setlocalversion: Use "grep -q" instead of piping output to "read dummy"
  modpost: fix ALL_INIT_DATA_SECTIONS
  Kbuild: centralize MKIMAGE and cmd_uimage definitions
  headers_check: recursively search for linux/types.h inclusion
  scripts/Kbuild.include: Fix portability problem of "echo -e"
  scripts: dtc: fix compile warnings
  kbuild: clean up samples directory
  kbuild: disable -Wmissing-field-initializers for W=1
