f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

07d0c94a46 Add support to eliminate a context switch per crypto op when using the
software crypto device:

o record crypto device capabilities in each session id
o add a capability that indicates if the crypto driver operates synchronously
o tag the software crypto driver as operating synchronously

This commit also introduces crypto session id macros that cleanup their
construction and querying.

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)

b4b138c27f Including <sys/stdint.h> is (almost?) universally only to be able to use
%j in printfs, so put a newsted include in <sys/systm.h> where the printf
prototype lives and save everybody else the trouble.

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)

45e10ed9ef o instead of applying arbitrary tunables, just honor the COP_F_BATCH
flag that can be marked on each symmetric op
o eliminate hw.ubsec.maxbatch and hw.ubsec.maxaggr since they are not
  needed anymore
o change ubsec_feed to return void instead of int since zero is always
  returned and noone ever looked at the return value

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

9967cafc49 Correct mbuf packet header propagation. Previously, packet headers
were sometimes propagated using M_COPY_PKTHDR which actually did
something between a "move" and a  "copy" operation.  This is replaced
by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it
from the source mbuf) and m_dup_pkthdr which copies the packet
header contents including any m_tag chain.  This corrects numerous
problems whereby mbuf tags could be lost during packet manipulations.

These changes also introduce arguments to m_tag_copy and m_tag_copy_chain
to specify if the tag copy work should potentially block.  This
introduces an incompatibility with openbsd which we may want to revisit.

Note that move/dup of packet headers does not handle target mbufs
that have a cluster bound to them.  We may want to support this;
for now we watch for it with an assert.

Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.

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.
