Function 'bitmap_empty' has it's own implementation.
But it's clearly as simple as:
find_first_bit(src, nbits) == nbits
The same is true for 'bitmap_full'.
Underscored versions of 'bitmap_[empty,full]' are not
needed anymore and so removed too.

It's about SHMLBA definition.
For aarch32 glibc defines it as (__getpagesize () << 2).
