-Subject: tools include: Adopt linux/bits.h
-
-From: Arnaldo Carvalho de Melo <acme@redhat.com>
-
-commit ba4aa02b417f08a0bee5e7b8ed70cac788a7c854 upstream.
-
-So that we reduce the difference of tools/include/linux/bitops.h to the
-original kernel file, include/linux/bitops.h, trying to remove the need
-to define BITS_PER_LONG, to avoid clashes with asm/bitsperlong.h.
-
-And the things removed from tools/include/linux/bitops.h are really in
-linux/bits.h, so that we can have a copy and then
-tools/perf/check_headers.sh will tell us when new stuff gets added to
-linux/bits.h so that we can check if it is useful and if any adjustment
-needs to be done to the tools/{include,arch}/ copies.
