bus_dma does and several drivers depend on it. in particular,
both re(4) and ath(4) would both spew "can't map mbuf" messages
as rapidly as possible (spamming the 9600 bps console) and
effectively locking up the interface until ifconfig "down up"
cycle was run. with this fix, i get a much, much slower spew
of messages, and the interface (re(4)) continues to operate.
The bug displayed itself by locking up console output on a 7043-140
following a powercycle. This may also have been the cause of bogus
interrupts on motorola class machines.
It is unclear that this interrupt fails to latch as int2_wait_fifo()
depends on it doing so and appears to work. Furthermore, we were previously
unconditionally unmasking the interrupt 0 vector, which led to more
'unexpected interrupt' messages on the console, rather than avoiding them.

IPv6 interface address (e.g., sin6_addr fe80::200:24ff:fec3:4bac
sin6_scope_id 1), set a multicast interface with
setsockopt(,IPPROTO_IPV6,IPV6_MULTICAST_IF,), and sendto(2) multicast
destinations with "wildcard" scope ID, 0, without error EHOSTUNREACH.
Prior to this patch, sendto(2) would exit with EHOSTUNREACH, even
though the scope ID was unambiguously specified both by bind(2)
and setsockopt(2). This was a bug because it broke old applications.
Thanks JINMEI Tatuya for the patch!
compiles, where some other system header #defines sc_sp.
In gre_ioctl, GREDSOCK case, do not try to delete sc_fp if it is
NULL.
Move GREDSOCK and GRESSOCK definitions to where the other GRE ioctls
are defined.
Remove #ifdef GRESSOCK, it's unnecessary now that the feature is
complete.
* we now don't rely on having console linear-mapped (that was terribly
broken, really)
* also, this can be used as generic ibm4xx mapiodev()/unmapiodev()
OK by matt@
with a build problem for sparc. The reason is that <dev/tc/sticio.h>
(yes, irrelevant for sparc...) wants NBPG declared, but for sparc user-land
that symbol is not available since sun4/sun4c/sun4m do not all share the
same page size.
* ppc4xx_tlb_mapiodev(): resolve pa to va from reserved TLB entries
OK by matt@
XXX we'll keep TLB_NRESERVED defined until we fix explora to use new API
error. It now correctly sets bp->b_resid to the full size of the buffer.
The failed SCSI read/write command allways contains the complete buffer.
When encountering a read (or write) error, the scsipi stack sets the
xs->resid to zero since the command has been accepted by the drive. The
scsi command set does not allow a partial read or write to be performed and
will signal a success or an error.
* don't try to decode vendor-specific PVR, print raw value instead.
* panic() if we see cache wasn't probed, we'd crash later anyway.
* rework the way PVR gets translated to core name.
* while there, normalize printf format ("%s: ...", device_xname(self), ...).

file system that covers the whole disk but marking most of it in use somehow.
Make this easier to deal with by detecting an existing RISC iX partition and
displaying its starting cylinder.
This program should really go away and its job be done by sysinst and/or
disklabel, but not today.
the device and since we count from zero its equal to the number of sectors
and thus one higher than the last sector.
This fixes the read/write problems on the (raw) device where the last
sector was not readable/writable.
macros, __BIT, __BITS, SHIFTIN, SHIFTOUT, and __arraycount() from
lib/libkern/libkern.h to sys/cdefs.h. Add a __-prefix to SHIFTIN
and SHIFTOUT, and add a manual page for the bit-twiddling macros,
bits(3).
Make the __BIT and __BITS macros "widthless," as best I can, by
changing their type to uintmax_t from uint32_t. XXX The manual
page lags this change by a bit.
Define __PRIxBIT and __PRIxBITS printf(3) format strings.
