The pair is of use only in debug or LOCKPROF kernels, but was passed (zeroed)
for many locks even in production kernels.
While here whack the tid argument from wlock hard and xlock hard.
There is no kbi change of any sort - "external" primitives still accept the
pair.
The bwn(4) driver requires a number of extensions to the bhnd(4) PMU
interface to support external configuration of PLLs, LDOs, and other
parameters that require chipset or PHY-specific workarounds.
These changes add support for:
- Writing raw voltage register values to PHY-specific LDO regulator
registers (required by LP-PHY).
- Enabling/disabling PHY-specific LDOs (required by LP-PHY)
- Writing to arbitrary PMU chipctrl registers (required for common PHY PLL
reset support).
- Requesting chipset/PLL-specific spurious signal avoidance modes.
- Querying clock frequency and latency.
Additionally, rather than updating legacy PWRCTL support to conform to the
new PMU interface:
- PWRCTL API is now provided by a bhnd_pwrctl_if.m interface.
- Since PWRCTL is only found in older SSB-based chipsets, translation from
bhnd(4) bus APIs to corresponding PWRCTL operations is now handled
entirely within the siba(4) driver.
- The PWRCTL-specific host bridge clock gating APIs in bhnd_bus_if.m have
been lifted out into a standalone bhnd_pwrctl_hostb_if.m interface.

On KERN_NO_SPACE error, as it is returned now, vm_map_find() continues
the loop searching for the suitable range for the requested mapping
with specific alignment. Since the vm_map_findspace() succesfully
finds the same place, the loop never ends.
The errors returned from vm_map_stack() completely repeat the behavior

The test creates a D library with a "depends_on library" pragma
referencing a non-existent library, and expects compilation to fail.
However, as far as I can tell, libdtrace is supposed simply abort
compilation of the library in this case, and continue. This behaviour
is desirable when adding libraries which depend on optional KLDs, for
example.

BHND Wi-Fi chipsets and SoCs share a common DMA engine, operating within
backplane address space. To support host DMA on Wi-Fi chipsets, the bridge
core maps host address space onto the backplane; any host addresses must
be translated to their corresponding backplane address.
- Defines a new bhnd_get_dma_translation(9) API to support querying DMA
address translation parameters from the bhnd(4) bus.
- Extends bhndb(4) to provide DMA translation descriptors from a DMA
address translation table defined in the host bridge-specific
bhndb_hwcfg.
- Defines bhndb(4) DMA address translation tables for all supported host
bridge cores.
- Extends mips/broadcom's bhnd_nexus driver to return an identity (no-op)
DMA translation descriptor; no translation is required when addressing
the SoC backplane.

On BHND MIPS SoCs, this replaces the use of hard-coded MIPS IRQ#s in the
common bhnd(4) core drivers; we now register an INTRNG child PIC that
handles routing of backplane interrupt vectors via the MIPS core.
On BHND PCI devices, backplane interrupt vectors are now routed to the
PCI/PCIe host bridge core when bus_setup_intr() is called, where they are
dispatched by the PCI core via a host interrupt (e.g. INTx/MSI).
The bhndb(4) bridge driver tracks registered interrupt handlers for the
bridged bhnd(4) devices and manages backplane interrupt routing, while
delegating actual bus interrupt setup/teardown to the parent bus on behalf
of the bridged cores.

Just like for i686 on x86-64, this new vDSO is responsible for padding

The problem happens when the writes have offsets and sizes aligned with
a filesystem's recordsize (maximum block size). In this scenario
dmu_tx_assign() would fail because of being over the quota, but the uio
would already be modified in the code path where we copy data from the
uio into a borrowed ARC buffer. That makes an appearance of a partial
write, so zfs_write() would return success and the uio would be modified
consistently with writing a single block.
That bug can result in a data loss because the writes over the quota
would appear to succeed while the actual data is being discarded.
This commit fixes the bug by ensuring that the uio is not changed until
after all error checks are done. To achieve that the code now uses
uiocopy() + uioskip() as in the original illumos design. We can do that
now that uiocopy() has been updated in r326067 to use
vn_io_fault_uiomove().

uiocopy() is currently unused, its purpose is copy data from a uio
without modifying the uio. It was in use before the vn_io_fault support
was added to ZFS, at which point our code diverged from the illumos code
a little bit. Because ZFS is the only (potential) user of the function
we are free to modify it to better suit ZFS needs.
The intention behind this change is to remove the differences introduced
earlier in zfs_write().
While here, re-implement uioskip() using uiomove() with
uio_segflg == UIO_NOCOPY.
The story of uioskip is the same as with uiocopy.
