      bluetooth: don't use bitmaps for random flag accesses · e1cff700
      Linus Torvalds authored
      The bluetooth code uses our bitmap infrastructure for the two bits (!)
      of connection setup flags, and in the process causes odd problems when
      it converts between a bitmap and just the regular values of said bits.
      
      It's completely pointless to do things like bitmap_to_arr32() to convert
      a bitmap into a u32.  It shoudln't have been a bitmap in the first
      place.  The reason to use bitmaps is if you have arbitrary number of
      bits you want to manage (not two!), or if you rely on the atomicity
      guarantees of the bitmap setting and clearing.
      
      The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
      clear the bit values, but considering that it then copies the bitmaps
      around with "bitmap_to_arr32()" and friends, there clearly cannot be a
      lot of atomicity requirements.
      
      So just use a regular integer.
      
      In the process, this avoids the warnings about erroneous use of
      bitmap_from_u64() which were triggered on 32-bit architectures when
      conversion from a u64 would access two words (and, surprise, surprise,
      only one word is needed - and indeed overkill - for a 2-bit bitmap).
      
      That was always problematic, but the compiler seems to notice it and
      warn about the invalid pattern only after commit 0a97953f ("lib: add
      bitmap_{from,to}_arr64") changed the exact implementation details of
      'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
