but because of a bug it was a no-op, so we were still using offsets in native
byte order for the host. Do it properly this time, bump version to 4 and set
the G_ELI_FLAG_NATIVE_BYTE_ORDER flag when version is under 4.

to kproc_xxx as they actually make whole processes.
Thos makes way for us to add REAL kthread_create() and friends
that actually make theads. it turns out that most of these
calls actually end up being moved back to the thread version
when it's added. but we need to make this cosmetic change first.
I'd LOVE to do this rename in 7.0 so that we can eventually MFC the
new kthread_xxx() calls.
- Use thread_lock() rather than sched_lock for per-thread scheduling
sychronization.
- Use the per-process spinlock rather than the sched_lock for per-process
scheduling synchronization.

o make all crypto drivers have a device_t; pseudo drivers like the s/w
crypto driver synthesize one
o change the api between the crypto subsystem and drivers to use kobj;
cryptodev_if.m defines this api
o use the fact that all crypto drivers now have a device_t to add support
for specifying which of several potential devices to use when doing
crypto operations
o add new ioctls that allow user apps to select a specific crypto device
to use (previous ioctls maintained for compatibility)
o overhaul crypto subsystem code to eliminate lots of cruft and hide
implementation details from drivers
o bring in numerous fixes from Michale Richardson/hifn; mostly for
795x parts
o add an optional mechanism for mmap'ing the hifn 795x public key h/w
to user space for use by openssl (not enabled by default)
o update crypto test tools to use new ioctl's and add cmd line options
to specify a device to use for tests
These changes will also enable much future work on improving the core
crypto subsystem; including proper load balancing and interposing code
between the core and drivers to dispatch small operations to the s/w
driver as appropriate.
These changes were instigated by the work of Michael Richardson.

We can't bind to a CPU which is not yet on-line, so add code that wait for
CPUs to go on-line before binding to them.

This way one will be able to use provider encrypted on eg. i386 on
eg. sparc64. This doesn't really buy us much today, because UFS isn't
endian agnostic.
We retain backward compatibility by setting G_ELI_FLAG_NATIVE_BYTE_ORDER
flag on devices with version number less than 2 and not converting the
offset.
case panic on sparc64.
The problem is in MD5(9) implementation. The Encode() function takes
'unsigned char *output' as its first argument, which is then assigned to
'u_int32_t *op'. If the 'output' argument is not 4 byte aligned (and in
geli(8) case it is not), sparc64 machine will panic.
I don't know how to fix MD5(9) in a clean way, so I'm implementing a
work-around in geli(8).
