af2b2a7331 Redo locking for proper SMP operation:
o replace driver-global lock with three locks: one for the handling of mcr1
  operations, one for handling of mcr2 operations, and one for the mcr1
  free list
o mark the interrupt handler MPSAFE
o don't use locking on detach; disabling interrupts is sufficient (I think)

b7c4858f1e o add crypto driver glue for using the new rndtest driver/module; this is
conditional in each driver on foo_RNDTEST being defined_
o bring HIFN_DEBUG and UBSEC_DEBUG out to be visible options; they control
  the debugging printfs that are set with hw.foo.debug (e.g. hw.hifn.debug)

45a0c8fe56 fix memory allocation problems and collateral damage:
o create a separate tag for each object allocated with bus_dmamem_alloc so
  the tag's maxsize is setup appropriately; this reduces memory allocation
  for the queue descriptors from 16M to what it should be and also fixes
  memory allocation for public key operands
o release bus dma resources on detach so module usage doesn't leak
o remove public key op disable now that bus dma memory allocation is fixed
o collect attach error handling in one place

f96d19da13 Track openbsd changes that don't affect us yet (PK supoprt is
currently disabled):

o Don't use constants for the output parameter, use the iparam count as a
  pointer to the first result location.
o Fix bits vs bytes counting problems.
o Split out the hardware and software normalization versions of modexp.
o Enable hardware normalization for chips that support it.
o On reset, disable hardware normalization for 582x and make sure the
  chip is in little endian mode.
o Since sw normalization is now the only option, simplify normalization
  handling.

Also fix RNG harvesting: disabling PK support (for the moment) had disabled
the MCR2 interrupt; consider both KEY support and RNG support when deciding
whether or not to enable it.
