sys/vm swap_pager.c swap_pager.h vm_swap.c
Log:
The swap bitmap allocator was not calculating the bitmap size properly
in the face of non-stripe-aligned swap areas. The bug could cause a
panic during boot.
Refuse to configure a swap area that is too large (67 GB or so)
Properly document the power-of-2 requirement for SWB_NPAGES.
The patch is slightly different then the one Tor enclosed in the P.R.,
but accomplishes the same thing.
