- Don't require all receivers of ipis to wait for all other receivers,
only that the sender wait for all receivers. This should reduce the
amount of time spent with interrupts disabled, which may be a cause
of ipi timeouts.

mutexes are supposed to only be used as leaf mutexes, and what appear
to be separate pool mutexes could be aliased together, it is bad idea
for a thread to attempt to hold two pool mutexes at the same time.
Slightly rearrange the code in kern_open() so that FILE_UNLOCK() is
called before calling VOP_GETVOBJECT(), which will grab the v_vnlock
mutex.
Setting the LD_DUMP_REL_PRE or LD_DUMP_REL_POST environment variables
cause rtld-elf to output a table of all relocations.
This is useful for debugging.

This will mean the bktr and other definitions can go back to their

- Mark that it cannot handle greater than 4GB of RAM at this time. Fixing
that will come later. Fail any attempts to dump above thati limit.
- If a call to aac_disk_dump() needs to be split into multiple i/o's,
increment the virtual offset after each i/o instead of just dumping the
same offset over and over again.
- Bail out if bus_dmamap_load() returns an error. Error recovery is likely
not possible.
Rev 1.201 also removed the out of file descriptor warning messages

the values that are "reserved", but they are not reserved anywhere else
so I'm assuming this is what they were unreserved for. Unfortunately
some of the values for local syscons types overlap the values used for
sbus adapters elsewhere, so we can't have all the same values.
- Move prototypes for sparc64-specific helper functions from bus.h to
bus_private.h
- Move the method pointers from struct bus_dma_tag into a separate
structure; this saves some memory, and allows to use a single method
table for each busdma backend, so that the bus drivers need no longer
be changed if the methods tables need to be modified.
- Remove the hierarchical tag method lookup. It was never really useful,
since the layering is fixed, and the current implementations do not
need to call into parent implementations anyway. Each tag inherits
its method table pointer and cookie from the parent (or the root tag)
now, and the method wrapper macros directly use the method table
of the tag.
- Add a method table to the non-IOMMU backend, remove unnecessary
prototypes, remove the extra parent tag argument.
- Rename sparc64_dmamem_alloc_map() and sparc64_dmamem_free_map() to
sparc64_dma_alloc_map() and sparc64_dma_free_map(), move them to a
better place and use them for all map allocations and deallocations.
- Add a method table to the iommu backend, and staticize functions,
remove the extra parent tag argument.
- Change the psycho and sbus drivers to just set cookie and method table
in the root tag.
- Miscellaneous small fixes.
Also fixed the rest of ell (list) functions prototypes to include
a (commented out) terminating null pointer.

redundant paths to the same device.
This class reacts to a label in the first sector of the device,
which is created the following way:
# "0123456789abcdef012345..."
# "<----magic-----><-id-...>
echo "GEOM::FOX someid" | dd of=/dev/da0 conv=sync
NB: Since the fact that multiple disk devices are in fact the same
device is not known to GEOM, the geom taste/spoil process cannot
fully catch all corner cases and this module can therefore be
confused if you do the right wrong things.
NB: The disk level drivers need to do the right thing for this to
be useful, and that is not by definition currently the case.
Tests with openldap20 where successful whereas openldap21 didn't like
the way hdb-ldap accessed openldap (doesn't like non-bind access).
To activate the support put a USE_OPENLDAP=yes in your make.conf.
The OPENLDAPBASE is also optional and points to /usr/local as default.
