af3c78886f Alter the prototype of qsort_r(3) to match POSIX, which adopted the
glibc-based interface.

Unfortunately, the glibc maintainers, despite knowing the existence
of the FreeBSD qsort_r(3) interface in 2004 and refused to add the
same interface to glibc based on grounds of the lack of standardization
and portability concerns, has decided it was a good idea to introduce
their own qsort_r(3) interface in 2007 as a GNU extension with a
slightly different and incompatible interface.

With the adoption of their interface as POSIX standard, let's switch
to the same prototype, there is no need to remain incompatible.

C++ and C applications written for the historical FreeBSD interface
get source level compatibility when building in C++ mode, or when
building with a C compiler with C11 generics support, provided that
the caller passes a fifth parameter of qsort_r() that exactly matches
the historical FreeBSD comparator function pointer type and does not
redefine the historical qsort_r(3) prototype in their source code.

Symbol versioning is used to keep old binaries working.

ddfc9c4c59 newbus: Move from bus_child_{pnpinfo,location}_src to bus_child_{pnpinfo,location} with sbuf
Now that the upper layers all go through a layer to tie into these
information functions that translates an sbuf into char * and len. The
current interface suffers issues of what to do in cases of truncation,
etc. Instead, migrate all these functions to using struct sbuf and these
issues go away. The caller is also in charge of any memory allocation
and/or expansion that's needed during this process.

Create a bus_generic_child_{pnpinfo,location} and make it default. It
just returns success. This is for those busses that have no information
for these items. Migrate the now-empty routines to using this as
appropriate.

Document these new interfaces with man pages, and oversight from before.

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.

This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

Mark all obvious cases as MPSAFE.  All entries that haven't been marked

7c7c726bca siba(4): Ignore disabled per-core address match entries.
Previously, the address regions described by disabled admatch entries would
be treated as being mapped to the given core; while incorrect, this was
essentially harmless given that the entries describe unused address space
on the few affected devices.

We now perform parsing of per-core admatch registers and interrupt flags in
siba_erom, correctly skip any disabled admatch entries, and use the
siba_erom API in siba_add_children() to perform enumeration of attached
cores.

84d6a5d4a7 bhndb_pci(4): fix incorrect BHND_PCI_SRSH_PI workaround
On a SPROM-less device, the PCI(e) bridge core will be initialized with its
power-on-reset defaults; this can leave the SPROM-derived BHND_PCI_SRSH_PI
value pointing to the wrong backplane address. This value is used by the
PCI core when performing address translation between the static register
windows in BAR0 that map the PCI core's register block, and backplane
address space.

Previously, bhndb_pci(4) incorrectly used the potentially invalid static
BAR0 PCI register windows when attempting to correct the BHND_PCI_SRSH_PI
value in the PCI core's SPROM shadow.

Instead, we now read/update BHND_PCI_SRSH_PI by fetching the PCI core's
backplane address from the core enumeration table, and then using a dynamic
register window to explicitly map the PCI core's register block into BAR0.
