perf tools: Don't use code surrounded by __KERNEL__ We need to refactor code to be explicitely shared by the kernel and at least the tools/ userspace programs, so, till we do that, copy the bare minimum bitmap/bitops code needed by tools/perf.

perf tools: Add bitmap_or function into bitmap object Adding implementation os bitmap_or function to the bitmap object. It is stolen from the kernel lib/bitmap.o object. It is used in upcomming patches.

tools bitmap: Implement bitmap_equal() operation at bitmap API Extend tools bitmap API with bitmap_equal() implementation. The implementation has been derived from the kernel. Extend tools bitmap API with bitmap_free() implementation for symmetry with bitmap_alloc() function.
