radix tree test suite: Remove duplicate bitops code

2017-01-28T02:29:39+00:00

By adding __set_bit and __clear_bit to the tools include directory, we
can share the bitops code.  This reveals an include loop between kernel.h,
log2.h, bitmap.h and bitops.h.  Break it the same way as the kernel does;
by moving the kernel.h include from bitops.h to bitmap.h.

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.
