tools: Work around BITS_PER_LONG related build failure in objtool

2016-07-13T07:37:43+00:00

The objtool build fails with the recent changes to the bits-per-long
headers:

  tools/include/linux/bitops.h:12:0: error: "BITS_PER_LONG" redefined [-Werror]

Which got introduced by:

  bb9707077b4e tools: Copy the bitsperlong.h files from the kernel

Work it around for the time being.

tools: Remove bitops/hweight usage of bits in tools/perf

2015-01-16T20:49:29+00:00

We need to use lib/hweight.c for that, just like we do for lib/rbtree.c,
so tools need to link hweight.o. For now do it directly, but we need to
have a tools/lib/lk.a or .so that collects these goodies...

tools: Move bitops.h from tools/perf/util to tools/

2014-12-17T14:17:53+00:00

So that we better mirror the kernel sources and make it available for
other tools.
