Change Details

New function check_align_mask() checks for a too big mask/alignment as well as if the mask is indeed that of a power of two. If some check fails, it just calls panic(). Use check_align_mask() in uma_set_align_mask(), and also in uma_zcreate() to replace a KASSERT() (that was checking only for a power of 2).

New function check_align_mask() asserts (under INVARIANTS) that the highest bit of the mask is not set (see the comment) and the alignment is a power of two. Use check_align_mask() in uma_set_align_mask() and also in uma_zcreate() to replace the KASSERT() there (that was checking only for a power of 2).
