2016-07-15tools: Simplify BITS_PER_LONG definePeter Zijlstra1-21/+2
Do it using (__CHAR_BIT__ * __SIZEOF_LONG__), simpler, works everywhere, reduces the complexity by ditching CONFIG_64BIT, that was being synthesized from yet another set of defines, which proved fragile, breaking the build on linux-next for no obvious reasons. Committer Note: Except on: gcc version 4.1.2 20080704 (Red Hat 4.1.2-55) Fallback to __WORDSIZE in that case...

2016-07-13tools: Fix up BITS_PER_LONG settingArnaldo Carvalho de Melo1-5/+19
It was set based on CONFIG_64BIT, that is available only when using Kconfig, which we're working towards but not to the point of having this CONFIG variable set, so synthesize it from available compiler defined defines, __SIZEOF_LONG__ or, lacking that, __WORDSIZE.

2016-07-12tools: Copy the bitsperlong.h files from the kernelArnaldo Carvalho de Melo3-0/+27
We use it in bitops/__ffs.h and bitops/atomic.h, that we also got from the kernel, but were getting it from either newer systems that carry it in /usr/include, or from the kernel sources, that we decided not to touch from tools/ code. Fix it.

2016-03-09tools: Copy hashtable.h into tools directoryJosh Poimboeuf3-3/+3
Copy hashtable.h from include/linux/tools.h. It's needed by objtool in the next patch in the series. Add some includes that it needs, and remove references to kernel-specific features like RCU and __read_mostly. Also change some if its dependency headers' includes to use quotes instead of brackets so gcc can find them.

2015-05-08tools include: Add basic atomic.h implementation from the kernel sourcesArnaldo Carvalho de Melo1-0/+63
Uses the arch/x86/ kernel code for x86_64/i386, fallbacking to a gcc intrinsics implementation that has been tested in at least sparc64. Will be used for reference counting in tools/perf.

2015-01-16tools: Remove bitops/hweight usage of bits in tools/perfArnaldo Carvalho de Melo4-0/+11
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...
