on the Itanium2 system I have when we use up *all* of the initial 256MB
direct mapped region before we are ready to dynamically expand it.
The machine that I have has 4 cpus and a very big hole in the middle.
This makes the bogus '(last_address - first_address) / PAGE_SIZE'
calculations especially dangerous and caused many millions of initial
PV/PTE's to be preallocated.
o "struct addrinfo" contains a pointer to "struct sockaddr,"
not "struct sockaddr" itself
o the function takes a pointer to "struct in*_addr", not to
"struct sockaddr," so the address length must be corresponding

o Add preliminary support for Cirrus Logic CL-PD6729 using PCI
interrupts. To use it you you need to set hw.pcic.pd6729_intr_path
to 2. This is allow us to still default to ISA intrrupt path for
this part (which is found much more often in laptops using ISA IRQs).
But some PCI cards have this part on them and this should allow them
to be used. It is untested on PCI, but it seems to not break the ISA
case.
o Better sysctl descriptions (I hope).

with the previous implementation. One noticeable difference is the order
in which messages are printed. In the previous implementation, the
command "lpc topq lp 1 20 300" might print:
lp:
moved cfA300some.host.org
moved cfA020some.host.org
moved cfA001some.host.org
while in the new implementation you'll see:
lp:
moved cfA001some.host.org
moved cfA020some.host.org
moved cfA300some.host.org
The final order of jobs in the queue is exactly the same, it's just
that the jobs are now moved in the same order they were specified,
instead of being moved (and thus listed) in the reverse order.
The new implementation also supports more options for how to select
which jobs should be moved. The previous topq allowed the user to
select jobs based on a job number, or based on a userid:
topq lp 17
topq lp drosehn
The new one also allows for a range of job numbers, or a hostname
(matching jobs that were sent from that hostname). To specify a
hostname, you must prefix it with an '@'-sign:
topq lp 17
topq lp 15-25
topq lp drosehn
topq lp @some.host.com
or a combination of those things:
topq lp drosehn:17
topq lp 15-25:drosehn
topq lp 15-25@some.host.edu
topq lp gad:15-25@some.host.edu
Futhermore, in the new implementation the user can also use
filename-style pattern-matching on the userid or hostname fields:
topq lp dros[ie]hn
topq lp @samba*
topq lp gad@*freebsd.org
(although the user should probably include those in quotes when they
are specifying the topq command as part of the 'lpc' command, just
to make sure the pattern-matching characters are not expanded by
whatever shell they are typing the command into)
The operator can still specify several of these job-specifiers in a
single command:
topq lp 17 22 27 drosihn:23 gad@*freebsd.org 97
If a job is matched by multiple job-specifiers on a single command,
then its final position in the queue is based on the first job-specifer
which matched it.
The previous implementation also recognized a jobnumber followed by
a hostname (with no separator), or a hostname:jobnumber, although
neither of these options were documented. Eg:
topq lp 42some.host.org
topq lp some.host.org:42
The new version allows the first one, and will also recognize the
second one *iff* the hostname includes a period (otherwise it is
assumed to be a userid followed by a job number). Both remain
undocumented, and are only provided in case there were some users
who did know about those options, and are used to typing them in.
The new implementation also fixes a few subtle security issues in
the old one (mainly just making sure all error-messages are printed
while the process is "not-priv"), avoids integer-overflow issues on
bad user input, and prints out more descriptive messages in a number
of circumstances.
The new bottomq command accepts all the same arguments as topq, but
moves the selected jobs to the bottom of the queue instead of the top.
reflect much valuable feedback from wollman. More details on the new
'lpc topq' are in the log message for revision 1.2 of lpc/movejobs.c.
The previous implementation of 'lpc topq' is available as 'lpc xtopq',
in case there are any problems noticed in the new implementation. If
there are no problems with this version, a later update will remove the
'lpc xtopq' command.
