From ba4aa02b417f08a0bee5e7b8ed70cac788a7c854 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 25 Sep 2018 10:55:59 -0300 Subject: tools include: Adopt linux/bits.h 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.
