are equal. Unfortunately, RFC 3484 requires that otherwise equal objects
remain in the order supplied by the DNS server. The present code attempts
to deal with this by returning -1 for objects that are equal (i.e.,
returns that the first parameter is less then the second parameter).
Unfortunately, the qsort API does not state that the first parameter
passed in is in any particular position in the list.

- Added bhnd_pmu driver implementations for PMU and PWRCTL chipsets,
derived from Broadcom's ISC-licensed HND code.
- Added bhnd bus-level support for routing per-core clock and resource
power requests to the PMU device.
- Lift ChipCommon support out into the bhnd module, dropping
bhnd_chipc.

As the xinstall(8) utility had to be patched up to work with the POSIXly
correct basename()/dirname() prototypes, we make it pretty hard to build
previous versions of FreeBSD on HEAD. xinstall(8) is part of the
bootstrap tools.
Add some logic to <libgen.h> to automatically detect bad calls to
dirname() based on the type of the argument. If the argument is of type
'const char *', we simply fall back to calling into dirname@FBSD_1.0
directly.
I'll also give basename() similar treatment when importing the
thread-safe version of that function.

This adds support for performing platform_reset() on all supported
devices, using early boot enumeration of chipc capabilities and
available cores.
- Added Broadcom-specific MIPS CP0 register definitions used by
BCM4785-specific reset handling.
- Added a bcm_platform structure for tracking chipc/pmu/cfe platform
data.
- Extended the BCMA EROM API to support early boot lookup of core info
(including port/region mappings).
- Extended platform_reset() to support PMU, PMU+AOB, and non-PMU
devices.

Rather than enabling the I/O MMU when the vmm module is loaded,
defer initialization until the first attempt to pass a PCI device
through to a guest. If the I/O MMU fails to initialize or is not
present, than fail the attempt to pass a PCI device through to a
guest.
The hw.vmm.force_iommu tunable has been removed since the I/O MMU is
no longer enabled during boot. However, the I/O MMU support can be
disabled by setting the hw.vmm.iommu.enable tunable to 0 to prevent
use of the I/O MMU on any systems where it is buggy.

Summary:
First time BSS is cleared in booke_init(), Second time it's cleared in
powerpc_init(). Any variable initialized between two those guys gets wiped out
what is wrong. In particular it wipes tlb1_entries initialized by tlb1_init(),
which was fine when tlb1_init() was called a second time, but this was removed
in r304656.

Now both OpenBSD and NetBSD return failure, i.e. no line and set error

libifc (pronounced lib-ifconfig) aims to be a light abstraction layer between
programs and the kernel APIs for managing the network configuration.
This should hopefully make programs easier to maintain, and reduce code
duplication.
Work will begin on making ifconfig(8) use this library in the near future.
This code is still evolving. The interface should not be considered stable until
it is announced as such.

In vf(w)printf.c here it is more easy to save __SERR, clear and restore it.

If there was some error, e.g. the sleep was interrupted, as in the
referenced PR, do_rw_rdlock() did not cleared URWLOCK_READ_WAITERS.
Since unlock only wakes up write waiters when there is no read
waiters, for URWLOCK_PREFER_READER kind of locks, the result was
missed wakeups for writers.
In particular, the most visible victims are ld-elf.so locks in
processes which loaded libthr, because rtld locks are urwlocks in
prefer-reader mode. Normal rwlocks fall into prefer-reader mode only
if thread already owns rw lock in read mode, which is not typical and
correspondingly less visible. In the PR, unowned rtld bind lock was
waited for in the process where only one thread was left alive.
Note that do_rw_wrlock() correctly clears URWLOCK_WRITE_WAITERS in
case of errors.
