Nuke incorrect usage of .Ar; replace it with .Vt, .Va or .Fa appropriately.
The .Ar mdoc(7) specifier should only be used when displaying command line
arguments.

output buffer, don't insert them at all. This prevents a buffer
*underrun* when the substitution consists completely of newlines
(e.g. `echo`) and the byte before the source buffer to which p
points is a '\n', in which case more characters would be removed
from the output buffer than were inserted.
This fixes certain port builds on sparc64.

an excessive close() on one of these descriptors would cause
a memory for this descriptor to be allocated in the internal
descriptor table. When this descriptor gets used again, e.g.
through the call to open() or socket(), the descriptor would
be erroneously left in the blocking mode, and the whole
application would get stuck on a blocking operation, e.g.,
in accept(2).
Prevent this bug from happening by disallowing close() against
non-active descriptors (return -1 and set errno to EBADF in
this case).

This machine uses a non-standard scheme to specify the interrupts to
be assigned for devices in PCI slots; instead of giving the INO
or full interrupt number (which is done for the other devices in this
box), the firmware interrupt properties contain intpin numbers, which
have to be swizzled as usual on PCI-PCI bridges; however, the PCI host
bridge nodes have no interrupt map, so we need to guess the
correct INO by slot number of the device or the closest PCI-PCI
bridge leading to it, and the intpin.
To do this, this fix makes the following changes:
- Add a newbus method for sparc64 PCI host bridges to guess
the INO, and glue code in ofw_pci_orb_callback() to invoke it based
on a new quirk entry. The guessing is only done for interrupt numbers
too low to contain any IGN found on e450s.
- Create another new quirk entry was created to prevent mapping of EBus
interrupts at PCI level; the e450 has full INOs in the interrupt
properties of EBus devices, so trying to remap them could cause
problems.
- Set both quirk entries for e450s; remove the no-swizzle entry.
- Determine the psycho half (bus A or B) a driver instance manages
in psycho_attach()
- Implement the new guessing method for psycho, using the slot number,
psycho half and property value (intpin).
Thanks go to the testers, especially Brian Denehy, who tested many kernels
for me until I had found the right workaround.

The current name is confusing, because it indicates to
the client that a bus_dmamap_sync() operation is not
necessary when the flag is specified, which is wrong.
The main purpose of this flag is to hint the underlying
architecture that DMA memory should be mapped in a coherent
way, but the architecture can ignore it. But if the
architecture does supports coherent mapping of memory, then
it makes bus_dmamap_sync() calls cheap.
This flag is the same as the one in NetBSD's Bus DMA.

nfs_lock.c. Right now, if we permit a signal to interrupt the sleep,
we will slip the lock and no process on that client, the server, or
any other client will be able to acquire the lock. This can happen,
for example, if a user hits Ctrl-C or Ctrl-T while a process is
waiting for the lock. By removing PCATCH, we prevent that from
happening, at the cost of not permitting a user-requested lock abort:
also nasty. However, a user interface bug might be preferable to a
serious semantic bug, so we go with that for now.
We need to teach the rpc.lockd/kernel protocol how to abort lock
requests, and rpc.lockd how to handle aborted lock requests; patches
for the kernel bit are floating around, but no rpc.lockd bit yet.

are not normally fatal in per-module builds, only when they are linked

to a buffer in the big key/data case, memmove() was used on pointers
to size_ts, but only sizeof(u_int32_t) bytes where copied. This broke
on big_endian architectures where sizeof(size_t) > sizeof(u_int32_t).
This bug broke portupgrade (by way of ruby_bdb1) on sparc64.

Use the special LUNLEN_SINGLE_LEVEL constant for
post Rev A4 hardware for single byte luns. Without
this change, Rev B hardware would place the single
byte of lun data in byte 0 of the lun structure when
it should be in byte 1. Since there are few if any
devices on the market that support multiple luns in
target mode, the corrupted lun field (which was only
corrupted for non-zero luns) wasn't hurting us.

that requires a dwarf2 runtime interpreter, which we do not have.
