idr: remove length restriction from idr_layer->bitmap
Currently, idr->bitmap is declared as an unsigned long which restricts
the number of bits an idr_layer can contain. All bitops can handle
arbitrary positive integer bit number and there's no reason for this
restriction.
Declare idr_layer->bitmap using DECLARE_BITMAP() instead of a single
unsigned long.
* idr_layer->bitmap is now an array. '&' dropped from params to
bitops.
* Replaced "== IDR_FULL" tests with bitmap_full() and removed
IDR_FULL.
* Replaced find_next_bit() on ~bitmap with find_next_zero_bit().
* Replaced "bitmap = 0" with bitmap_clear().
This patch doesn't (or at least shouldn't) introduce any behavior
changes.
