o Correct authorization check in CANSIGIO(), which suffered from incorrect
transcription during the (pcred,ucred) merge; this was not used for
the kill() system call, so does not affect direct explicit process
signalling.
Rearrange so we search for I/O port space as early as possible (i.e.
before console probing). Also fix a confusion between EFI's page size
which is fixed at 4096 and our own page size which is variable at compile
time.
Avoid the region used for thread0's trapframe when setting up the stack
for ia64_init. If we use this area for ia64_init's stack, it ends up
containing garbage which causes cpu_fork to die horribly later.
o Modify NFS rights comment to note that the early credential changes
to test for a home directory don't set up the additional groups, and
as such may limit users conservatively. This does not affect the
eventual credentials selected.
o Add a comment noting that the early setting of privileges for the purpose
of NFS home directory and root directory processing fails to include
additional groups. This doesn't impact the final credential, but does
mean that users may be denied login even when additional groups might
allow it.
* Use Intel's EFI headers instead of home-grown ones.
* Use the bootinfo's memory map if present instead of hard-coding SKI's
memory map.
* Record the location of the I/O Port Space if present in the memory map.

In the devfs case, have initproc attempt the easy cases of mounting /dev.
This works if /dev exists, or if / is read/write (nfsroot). If it is
too hard, leave it up to init -d (which will probably fail if /dev does
not exist, but there isn't much else we can do short of making a union
mount on /).
This means we get a proper /dev if you boot a 5.x kernel on a 4.x world,
which I happen to do often (the ramdisks on our install netboot servers
have 4.x userland worlds on them).
Fill out some gaps in ia64 DDB support. This involves generalising DDB's
breakpoint handling slightly to cope with the fact that ia64 instructions
are not located on byte boundaries.
Handle "identifier strings" right. Each ISA PnP card must have a
mandatory "card" identifier string. A logical devices on the ISA PnP
card may optionally have a "device" identifier string. Do not confuse
them.
The "card" identifier string is assigned to a logical device as the
default description string when the device is found. (If the "card"
identifier string has not been found, use the EISA PnP ID string.
Strictly speaking, this is an error.) We will override it when a
"device" identifier string is found later.
Implement comprehensive CVS/Template support to complement the Template
support that already exists for checkout. The -T option for cvs update
and cvs checkout may be used to cause CVS to retrieve/update the checkin
template when possible.
- Add workaround for the problematic PnP BIOS which does not assign
irq resource for the PS/2 mouse device node; if there is no irq
assigned for the PS/2 mouse node, refer to device.hints for an
irq number. If we still don't find an irq number in the hints
database, use a hard-coded value.
- Delete unused ivars.
- Bit of clean up in probe/attach.
- Add PnP ID for the PS/2 mouse port on some IBM ThinkPad models.
Rev 1.10 bogusly tested the kernel version, not the libc version.
The version of the kernel has no bearing on what is in libc.
We now search for basename in libc to determin if we need to include
the libiberty version in the build.
This is all still a bit bogus as it will (like the sysctl method) cause
basename.o to be linked into the cross-build as well as the host build. It
would probably be better to test if we were doing the initial host build and
unconditionally include that. Once we've generated the target libc we know
that basename is available. (maybe test for $TOOLS_PREFIX or something).
- Correctly increment the channel refcount in dsp_open() such that it is
no longer possible to unload the driver module while sound is playing
(which resulted in a panic).
- Fix a similar problem with the sndstat device that I found while looking
at the above.
- Append a newline character to error messages in pcm_unregister()
The code that sees a drive (at mount time) not in buffered mode and
attempts to set buffered mode was printing out "unable to set buffered
mode" no matter what. Oops.
Two style changes: Bring "maintained by" credit into a sect1info, and
move the ID string from a pubdate element into a comment on the
grounds that this document doesn't change rapidly enough to require
that the ID string to actually be rendered in the output.
Unbreak build-tools -- build and use up-to-date ${HEADERS}.
These might not be present in /usr/include, or they may be
incompatible with the version we are building (for library
upgrades/downgrades).
This stopped the RELENG_4 buildworld on a -CURRENT box.
Well, this only fixes the issue if MFC'ed. :-)
Fix off by one error introduced by the use of the ifnet_byindex()
macro. The commit log clearly states that the index given to the
macro is one higher than previously used to index the array. This
wasn't represented in the code and resulted in kernel page faults.

Fix locking on td_flags for TDF_DEADLKTREAT. If the comments in the code
are true that curthread can change during this function, then this flag
needs to become a KSE flag, not a thread flag.
fix savecore so that it works on the alpha after the size change
of dumpmag from an int to a u_long in rev 1.41 -- without this

Add a strcasecmp() call I forgot in my hurry to commit the previous fix.
Without this call, the hostname check would in some cases yield false
positives.
<jkh> "Hey Rocky, watch me eject this pccard outta my laptop!" "What,
again? That NEVER works!" "This time for sure!"
Minor overhaul of how we do interrupts for the pci interrupt routing
case to cope with card ejection better (read: make it not hand on so
many cards):
o Reintroduce func_intr and func_arg and use the to store the
interrupt handler to call.
o Create a pcic_pci_func_intr to call the real interrupt handler
iff the card hasn't been ejected.
o Remove some checks in pcic_setup_intr now that it is used
exclusively for isa routed interrupts.
o Defer the eject event until later too, but make sure we can't
do any client driver ISR calling in the interrum.
o Add some simple code to make sure that we don't attach more
than one child. This should fix pccardd starting twice
problem (ala single user -> multi-user when you started pccardd
by hand in SU).
MFC: after jkh thinks I've put the crack pipe away.
