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

Pull misc kbuild updates from Michal Marek:
 - Fix for make O=... perf-tar*
 - make tags revamp and fix for the fallout.  Patch for warnings about
   line breaks inside DEFINE_PER_CPU macros is pending
 - New coccinelle test

* 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  coccinelle: tests: unsigned value cannot be lesser than zero
  tags: Unify emacs and exuberant rules
  tags: Drop the _PE rule
  tags: Do not try to index defconfigs
  tags: Process Kconfig files in a single pass
  tags: Fix erroneous pattern match in a comment
  aic7xxx: Avoid name collision with <linux/list.h>
  tags: Treat header files as C code
  package Makefile: fix perf-tar targets when outdir is set
  scripts/tags.sh: Teach tags about more powerpc macros

/// Unsigned expressions cannot be lesser than zero. Presence of
/// comparisons 'unsigned (<|<=|>|>=) 0' often indicates a bug,
/// usually wrong type of variable.
///
/// To reduce number of false positives following tests have been added:
/// - parts of range checks are skipped, eg. "if (u < 0 || u > 15) ...",
/// developers prefer to keep such code,
/// - comparisons "<= 0" and "> 0" are performed only on results of
/// signed functions/macros,
/// - hardcoded list of signed functions/macros with always non-negative
/// result is used to avoid false positives difficult to detect by other ways
