While ld(4) is MP safe, many backends are not.
Add a flag for backends that are MP safe. Take KERNEL_LOCK when calling
into a backend that doesn't have the flag set. Do the same for the
discard routine.
Fixes PR 52462.
Defer sdmmc discard operations to the sdmmc task queue. Fixes a panic
introduced by ld.c r1.102.
validate length for discard operation and split operation when byte length
doesn't fit into 'int'.
make the sc_discard interface for the ld backend asynchronous and
signal completion through new callback lddiscardend. Use a standard
struct buf to pass disk address and range instead of two off_t values.
make lddiscard synchronous again. This is a requirement of the current
ffs discard code.
Initialize error also in the case where len=0, which just succeeds.
while here, assert that the len is indeed non-negative. this is already
confirmed by sys_fdiscard, but let's be sure.
reported by: GCC, but with different compile flags

While ld(4) is MP safe, many backends are not.

Add a flag for backends that are MP safe. Take KERNEL_LOCK when calling

discard routine.

Fixes PR 52462.

merge to -current.

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.

Sync with wrstuden-revivesa-base-2.

Complete device_t/softc split for the ld(4) attachments. This should
prevent crashes while attaching a drive.

Patch supplied by Juan RP in PR kern/39468.

Replace most gcc-specific __attribute__ uses with BSD-style sys/cdef.h
preprocessor macros.

Add a flags argument to the ld(4) flush handlers, and call these with a
"poll" flag when called from ld_shutdown().

This is the infrastructure part of kern/38655 - in itself it doesn't
fix the panic referenced in that PR.

XXX: At least ld_twa.c and perhaps ld_iop.c and ld_icp.c need to
check for this new poll flag and do something useful.

Revert my suggested fix for kern/38655 - that shouldn't have snuck in

- Eliminate B_ERROR (from HEAD).

Sync with HEAD.

It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

- Merge changes from the vmlocking branch.
- Eliminate opt_i2o.h, since I2OVERBOSE is gone.

Checkpoint work in progress. Seems to break block I/O but I am not sure
why yet:

- Avoid a NULL pointer dereference in bus_dmamap_sync.
- MP safety changes, incomplete.

- Pass the error number and residual count to biodone(), and let it handle
  setting error indicators. Prepare to eliminate B_ERROR.
- Add a flag argument to brelse() to be set into the buf's flags, instead
  of doing it directly. Typically used to set B_INVAL.
- Add a "struct cpu_info *" argument to kthread_create(), to be used to
  create bound threads. Change "bool mpsafe" to "int flags".
- Allow exit of LWPs in the IDL state when (l != curlwp).
- More locking fixes & conversion to the new API.

file ld_iop.c was added on branch netbsd-1-5 on 2001-10-25 17:54:01 +0000

Parameter group changes:

- Do FIELD_SET correctly for scalar types.
- Add some basic table ops.
- Push error reporting back into iop.c.
- Add some field index and (yet more) LAN defs to i2o.h.

Some changes from OpenBSD, and some of my own:

- More SCSI port defs.
- Nuke vtophys().
- Release resources in iop_init() upon failure.
- Don't use a message wrapper when initalising the outbound FIFO.
- A couple of field size/endian fixes.
- Just use iop_post() when we don't need special handling.
- IM_DISCARD is now pointless, since we don't queue at the driver level.
- Map data transfers from/to userspace directly.
- A few comment and stylistic changes.

Oops.

- Only configure un-claimed devices. Implement re-configuration.
- Adhere to the spec better in some places. Also, work around some quirks
  noted in the Linux I2O code.
- Register event handlers for the executive and RBS devices.
- Fix a number of buglets and tidy a little.
- Implement a message pass-through interface and some other useful ioctls.
