test_bitmap: unit tests for lib/bitmap.c This is mainly testing bitmap construction and conversion to/from u32[] for now. Tested: qemu i386, x86_64, ppc, ppc64 BE and LE, ARM. Signed-off-by: David Decotigny <decot@googlers.com> Signed-off-by: David S. Miller <davem@davemloft.net>

bitmap: replace bitmap_{from,to}_u32array with bitmap_{from,to}_arr32 over the kernel. Additionally to it: * __check_eq_bitmap() now takes single nbits argument. * __check_eq_u32_array is not used in new test but may be used in future. So I don't remove it here, but annotate as __used.

lib/test_bitmap.c: add optimisation tests Patch series "Bitmap optimisations", v2. These three bitmap patches use more efficient specialisations when the compiler can figure out that it's safe to do so. Thanks to Rasmus's eagle eyes, a nasty bug in v1 was avoided, and I've added a test case which would have caught it. This patch (of 4): This version of the test is actually a no-op; the next patch will enable it.

lib/test_bitmap.c: clean up test_zero_fill_copy() test case and rename Since we have separate explicit test cases for bitmap_zero() / bitmap_clear() and bitmap_fill() / bitmap_set(), clean up test_zero_fill_copy() to only test bitmap_copy() functionality and thus rename a function to reflect the changes. While here, replace bitmap_fill() by bitmap_set() with proper values.
