  "message": "bitmap: introduce bitmap_set, bitmap_clear, bitmap_find_next_zero_area\n\nThis introduces new bitmap functions:\n\nbitmap_set: Set specified bit area\nbitmap_clear: Clear specified bit area\nbitmap_find_next_zero_area: Find free bit area\n\nThese are mostly stolen from iommu helper. The differences are:\n\n- Use find_next_bit instead of doing test_bit for each bit\n\n- Rewrite bitmap_set and bitmap_clear\n\n  Instead of setting or clearing for each bit.\n\n- Check the last bit of the limit\n\n  iommu-helper doesn\u0027t want to find such area\n\n- The return value if there is no zero area\n\n  find_next_zero_area in iommu helper: returns -1\n  bitmap_find_next_zero_area: return \u003e\u003d bitmap size\n\nSigned-off-by: Akinobu Mita \u003cakinobu.mita@gmail.com\u003e\nCc: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: \"David S.
