XXX: Most of the CTR() macros are called with callout_lock spin mutex
held, thus won't be logged into file, if KTR_ALQ is used. Moving the
CTR() macros out from the spinlocked code would require copying of all
arguments. I'm too lazy to do this.

- document the (new MI, old MD) `halt' command
- document the (new MI, old MD) `reboot' alias
- remove documentation of the removed `registers' command. The `r' alias
for `reset' is now prevented better by the ambiguity between `reset' and
`reboot'.
(PICs) rather than interrupt sources. This allows interrupt controllers
with no interrupt pics (such as the 8259As when APIC is in use) to
participate in suspend/resume.
- Always register the 8259A PICs even if we don't use any of their pins.
- Explicitly reset the 8259As on resume on amd64 if 'device atpic' isn't
included.
- Add a "dummy" PIC for the local APIC on the BSP to reset the local APIC
on resume. This gets suspend/resume working with APIC on UP systems.
SMP still needs more work to bring the APs back to life.
The MFC after is tentative.

vnode_pager_generic_getpages(): (1) that VOP_BMAP() is unsupported by the
underlying file system and (2) an error in performing the VOP_BMAP().
Previously, vnode_pager_generic_getpages() assumed that all errors were
of the first type. If, in fact, the error was of the second type, the
likely outcome was for the process to become permanently blocked on a busy
page.

not trust jails enough to execute audit related system calls. An example of
this is with su(1), or login(1) within prisons. So, if the syscall request
comes from a jail return ENOSYS. This will cause these utilities to operate
as if audit is not present in the kernel.
Looking forward, this problem will be remedied by allowing non privileged
users to maintain and their own audit streams, but the details on exactly how
this will be implemented needs to be worked out.
This change should fix situations when options AUDIT has been compiled into
the kernel, and utilities like su(1), or login(1) fail due to audit system
call failures within jails.
This is a RELENG_6 candidate.

(the group of watchpoint commands, and the `reset' command).
NetBSD has sorted everything alphabetically, but I think we would have
too many commands for that if all commands were actually documented
here, so this commit moves towards alphabetical order in several sections:
- section for pure ddb (non-"show") commands. Now contains the watchpoint
commands and is mostly in "logical" order.
- section for pure ddb "show" commands
- similarly for auxilary commands. Most of these are currently missing
here.
is suspending/suspended. Doing so may result in deadlock. Instead, set the
(new) IN_LAZYACCESS flag, that becomes IN_MODIFIED when suspend is lifted.
Change the locking protocol in order to set the IN_ACCESS and timestamps
without upgrading shared vnode lock to exclusive (see comments in the
inode.h). Before that, inode was modified while holding only shared
lock.

since they just duplicated the MI `reset' command. Instead of removing
them, make `reboot' an MI alias for `reboot' since this gives a better
way of killing the `r' alias for `reset'. Remove the `registers' command
that was used to kill the alias.
Turn the powerpc and sparc64 MD `halt' command into an MI command.
A copy of sparc64/db_interface.c grew in sun4v just after I found the
extra reboot commands. It has not been changed, and is now not
identical. Duplicated commands come out duplicated in ddb's online
help, but cause large problems when used (e.g., on i386's with 2 halt's
and an hwatch, typing h doesn' give the expected message about an
ambiguous command, but hangs like the halt command or a looping parseri
would).
suppression is only needed at ends of lines, but rev.1.32 forced it
off precisely there.
The --More-- prompt is now cleared by explicitly forcing out the
whitespace in "\r \r". It might be better to use the line
editor's clearing functions, but these are currently static and not
much different.
