Title:
  Xenial kernel 4.4.0-155.182 fails to build perf with libnuma

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Xenial:
  Fix Released

Bug description:
  [Impact] 
  When libnuma-dev is installed on the build environment, tools/perf tries to build bench/numa.c, but in the current Xenial kernel in -proposed it fails:

    CC       bench/numa.o
  bench/numa.c: In function 'lfsr_32':
  bench/numa.c:729:24: error: implicit declaration of function 'BIT' [-Werror=implicit-function-declaration]
    const uint32_t taps = BIT(1) | BIT(5) | BIT(6) | BIT(31);
                          ^
  bench/numa.c:729:2: error: nested extern declaration of 'BIT' [-Werror=nested-externs]
    const uint32_t taps = BIT(1) | BIT(5) | BIT(6) | BIT(31);
    ^

  
  [Fix]
  Commit "UBUNTU: SAUCE: perf/bench: Drop definition of BIT in numa.c", applied for "Xenial update: 4.4.180 upstream stable release (LP: #1830176)" is causing build failures on tools/perf/bench after stable upstream commit "perf tools: No need to include bitops.h in util.h" removed the inclusion of the header file where the BIT() macro is defined.

  The fix is to revert the SAUCE patch and keep the definition of BIT()
  in loco in numa.c as done in 4.4 stable upstream.

  
  [Test Case]
  1. Install libnuma-dev package on the build environment.
  2. cd xenial/linux source directory.
  3. fakeroot debian/rules clean
  4. cd tools/perf
  5. make

  
  [Regression Potential] 
  Low. The fix is to revert a SAUCE patch that was applied to fix a build failure that has been fixed upstream and it's not needed anymore.
