Sync a list of HP-IB disk IDs with kernel's one.
Now bootloader can boot from 2202A, 7908A, 7911A, and 7941A.
Tested on 425t and HPDisk.

Make local variables static and read only ones const.

Use common macro for numbers of cylinders and blocks for HP-IB disks.
No binary changes.

Fix "rd(4) at punits not configured on HPDisk are misprobed" problem.
- check not only stat value returned by C_QSTAT command against
  each punit but also desc.d_name returned by C_DESC command
  because it looks HPDisk responds to commands against punits supported
  but not-configured punits at 1-3
- prepare rdreset_unit() function to manage reset punit ops during
  probe without valid softc

The stragety is taken from OpenBSD with several modification.
Tested on 425t with real 9122D and HPDisk emulating two 7937H drives.
Should be pulled up to netbsd-9.

Remove now unused buffer members from softc prepared only for rdreset().

Use proper integer types for HP-IB xfer parameters.
No visible regression on 425t and HPDisk.

Sync with rdreg.h integer type changes.

Remove unnecessary declarations.

Check bounds of RAW_PART by bounds_check_with_mediasize() as other drivers.
With this check, dd(1) without a count value against a raw partition
is terminated properly at the end of media.  Tested on 425t and HPDisk.
Should be pulled up to netbsd-9.

Check bounds of each partition by MI bounds_check_with_label(9).
The previous implementation was committed in rev 1.26 about 26 years ago
and it looks there is no quirk to use the old MD one.

Pass a correct dev_t arg to disk_ioctl().
Probably harmless.

Remove a duplicated static function declaration.

Set disk_geom parameters required by DIOCGPARTINFO in disk_ioctl().
With this change raid(4) no longer complains before mountroot:
RAIDframe: can't get disk size for dev rd0 (22)
Should be pulled up to netbsd-9.

Use proper RAW_PART macro rather than a magic number.

Remove more duplicated static function declarations.

Misc KNF and cosmetics.

Add empty DIOCCACHESYNC ioctl(2) for rd(4).
Without this raid(4) always complains on various raidctl(8) ops:
raid0: cache flush[0] to component 0 failed (22)
RAID1 configured by raid(4) just works HP-IB disks on hp300.

Explicitly include <sys/kernel.h> for hz(9) as man pages says.
XXX: it looks sys/param.h r1.615 and later also has extern int hz

Remove now unused buffer members from softc prepared only for rdreset().

Sync with HEAD.

Consistently use #define<tab> here.

Consistently use #define<tab> as rdreg.h.

No need to bother to use aprint_debug(9) inside #ifdef DEBUG block.

Pull HP-IB probe fixes from OpenBSD/hp300.
https://marc.info/?l=openbsd-cvs&m=113217630426615&w=2

Overhaul the way HP-IB devices are probed. We will now do an exhaustive
probe of the (slave, punit) tuple space, since this is the only way we
can get a dual disk or dual tape enclosure to attach two devices of the
same kind.

This allows using multiple rd(4) disk images on the same slave emulated
by HPDisk (and probably the real 9122D with dual floppy disk drives).

Thanks to Miod Vallat for suggesting this fix.

Move attach messages from common rdident() to explicit rdattach().

Cleanup duplicated CS/80 indentify structures.  From OpenBSD.
https://marc.info/?l=openbsd-cvs&m=113227249626888&w=2

Define the CS/80 identify structure only once and correctly, instead of
duplicating it in every CS/80 driver and using an hardcoded number for
its size.
No functional change.

Pick HP-IB describe structures changes from main kernel code here as well.

Include <sys/rndsource.h> where it is actually used.

I had removed <sys/rnd.h> from files that didn't mention anything of
the rnd(9) API.  But they included other files which assumed
<sys/rnd.h> had already been included.

Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
   to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
   source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
   avoid expensive operations on disabled entropy sources; make the
   rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
   have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
   system events, and skew between clocks, with a sample implementation
   for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files).  Tested with release
builds on amd64 and evbarm and live testing on amd64.

First step of random number subsystem rework described in
<20111022023242.BA26F14A158@mail.netbsd.org>.  This change includes
the following:

	An initial cleanup and minor reorganization of the entropy pool
	code in sys/dev/rnd.c and sys/dev/rndpool.c.  Several bugs are
	fixed.  Some effort is made to accumulate entropy more quickly at
	boot time.

	A generic interface, "rndsink", is added, for stream generators to
	request that they be re-keyed with good quality entropy from the pool
	as soon as it is available.

	The arc4random()/arc4randbytes() implementation in libkern is
	adjusted to use the rndsink interface for rekeying, which helps
	address the problem of low-quality keys at boot time.

	An implementation of the FIPS 140-2 statistical tests for random
	number generator quality is provided (libkern/rngtest.c).  This
	is based on Greg Rose's implementation from Qualcomm.

	A new random stream generator, nist_ctr_drbg, is provided.  It is
	based on an implementation of the NIST SP800-90 CTR_DRBG by
	Henric Jungheim.  This generator users AES in a modified counter
	mode to generate a backtracking-resistant random stream.

	An abstraction layer, "cprng", is provided for in-kernel consumers
	of randomness.  The arc4random/arc4randbytes API is deprecated for
	in-kernel use.  It is replaced by "cprng_strong".  The current
	cprng_fast implementation wraps the existing arc4random
	implementation.  The current cprng_strong implementation wraps the
	new CTR_DRBG implementation.  Both interfaces are rekeyed from
	the entropy pool automatically at intervals justifiable from best
	current cryptographic practice.

	In some quick tests, cprng_fast() is about the same speed as
	the old arc4randbytes(), and cprng_strong() is about 20% faster
	than rnd_extract_data().  Performance is expected to improve.

	The AES code in src/crypto/rijndael is no longer an optional
	kernel component, as it is required by cprng_strong, which is
	not an optional kernel component.

	The entropy pool output is subjected to the rngtest tests at
	startup time; if it fails, the system will reboot.  There is
	approximately a 3/10000 chance of a false positive from these
	tests.  Entropy pool _input_ from hardware random numbers is
	subjected to the rngtest tests at attach time, as well as the
	FIPS continuous-output test, to detect bad or stuck hardware
	RNGs; if any are detected, they are detached, but the system
	continues to run.

	A problem with rndctl(8) is fixed -- datastructures with
	pointers in arrays are no longer passed to userspace (this
	was not a security problem, but rather a major issue for
	compat32).  A new kernel will require a new rndctl.

	The sysctl kern.arandom() and kern.urandom() nodes are hooked
	up to the new generators, but the /dev/*random pseudodevices
	are not, yet.

	Manual pages for the new kernel interfaces are forthcoming.

  have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
  from sys/bufq.h to sys/bufq_impl.h.
  (is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c.  (not tested)

Add randomness sampling from hil, sd and rd devices.

New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

Update for sys/buf.h/disksort_*() changes.

Add prototypes, and make this compile with -Wall.  Remove register

Convert to new-style autoconfiguration; old-style config is no longer
supported.

Update from trunk:

Remove old-style disk instrumentation support.  Nothing uses it
anymore.

Remove the old-style disk instrumentation support.  Nothing uses it
anymore.

New generic disk framework.  Highlights:

	- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

Re-arrange things such that we can print out disk geometry regardless of
COMPAT_NOLABEL.

XXX One day when the world doesn't assume DEV_BSIZE bytes/sector, we'll be
able to actually use the stuff sensed from the drive, rather than a table.
