cd9660_readdir() to return the address of the file's first data block as
the inode number instead of the address of the directory entry, but
neglected to update cd9660_vget_internal() for the new inode numbering
scheme.
Since the NFS server calls VFS_VGET (cd9660_vget()) with inode numbers
returned through VOP_READDIR (cd9660_readdir()) when servicing a READDIRPLUS
request, these two interfaces must agree on the numbering scheme; failure to
do so caused panics and/or bogus information about the entries to be returned
to clients using READDIRPLUS (Solaris, FreeBSD w/ mount -o rdirplus).

to RS232 bridges, such as the one found in the DeLorme Earthmate USB GPS
receiver (which is the only device currently supported by this driver).
While other USB to serial drivers in the tree rely heavily on ucom, this
one is self-contained. The reason for that is that ucom assumes that
the bridge uses bulk pipes for I/O, while the Cypress parts actually
register as human interface devices and use HID reports for configuration
and I/O.
The driver is not entirely complete: there is no support yet for flow
control, and output doesn't seem to work, though I don't know if that is
because of a bug in the code, or simply because the Earthmate is a read-
only device.
- Various markup, typo, and wording fixes.
- Use &man.*;.
- Move sound(4) related changes to the multimedia support section.
- Add net.inet.tcp.rfc3042 and net.inet.tcp.rfc3390.
- Unify items which relates to multibyte support of userland
utilities.
multibyte character support:
- In CHadd(), avoid writing past the end of the character set bitmap when
the opposite-case counterpart of wide characters with values less than
NC have values greater than or equal to NC.
- In CHaddtype(), fix a braino that caused alphabetic characters to be
added to all character classes! (but only with REG_ICASE)

ia64_write_reg() and call these whenever we read or write registers from
and to memory. This way we correctly read registers from addresses in
the register cache and thus fixes backtraces when the saved registers
(such as rp and ar.pfs) are in dirty stacked registers.
also occupies a single slot. There's no need for any special handling
of Quads. While here, remove the silly make_quad() function. We have
the 2 longs on 32-bit machines already lined up in the argument array,
so we can fetch the Quad with a simple cast.
Before:
lseek(1,0x123456789,0xd0d0d0d0d0d0d0d0) = 4886718345 (0x123456789)
After:
lseek(1,0x123456789,SEEK_SET) = 4886718345 (0x123456789)
but with slightly cleaned up interfaces.
The KSE structure has become the same as the "per thread scheduler
private data" structure. In order to not make the diffs too great
one is #defined as the other at this time.
The KSE (or td_sched) structure is now allocated per thread and has no
allocation code of its own.
Concurrency for a KSEGRP is now kept track of via a simple pair of counters
rather than using KSE structures as tokens.
Since the KSE structure is different in each scheduler, kern_switch.c
is now included at the end of each scheduler. Nothing outside the
scheduler knows the contents of the KSE (aka td_sched) structure.
The fields in the ksegrp structure that are to do with the scheduler's
queueing mechanisms are now moved to the kg_sched structure.
(per ksegrp scheduler private data structure). In other words how the
scheduler queues and keeps track of threads is no-one's business except
the scheduler's. This should allow people to write experimental
schedulers with completely different internal structuring.
A scheduler call sched_set_concurrency(kg, N) has been added that
notifies teh scheduler that no more than N threads from that ksegrp
should be allowed to be on concurrently scheduled. This is also
used to enforce 'fainess' at this time so that a ksegrp with
10000 threads can not swamp a the run queue and force out a process
with 1 thread, since the current code will not set the concurrency above
NCPU, and both schedulers will not allow more than that many
onto the system run queue at a time. Each scheduler should eventualy develop
their own methods to do this now that they are effectively separated.
Rejig libthr's kernel interface to follow the same code paths as
linkse for scope system threads. This has slightly hurt libthr's performance
but I will work to recover as much of it as I can.
Thread exit code has been cleaned up greatly.
exit and exec code now transitions a process back to
'standard non-threaded mode' before taking the next step.

denote a directory. Unfortunately, in the presence of GNU or POSIX
extensions, this code was checking the truncated filename stored in the
regular header rather than the full filename stored in the extended
attribute. As a result, long filenames with '/' in just the right
position would trigger this check and be erroneously marked as
directories. Move the check so it only considers the full filename.
Note: the check can't simply be disabled for archives that contain
these extensions because there are some very broken archivers out
there.

This should be MFC'd.
since otherwise the initial seek offset will contain the directory
offset of the filesystem block that contained its directory entry.
This bug was mostly harmless because typically the directory is
less than one filesystem block in size so the offset would be zero.
It did however generally break loading a kernel from the (large)
kernel compile directory.
Also reset the seek pointer when a new inode is opened in read_inode(),
though this is not actually necessary now because all callers set
it afterwards.

By using r8 instead of r14 to do the swap, we put the dst argument
in the return register. Since bcopy() doesn't clobber r8, we don't
have to do anything else. This fixes ports/textproc/aspell.
