841c7bb674 Remove static delcarations from {,un}register_pcic_intr declarations
in the not APIC_IO case.  This should silence the warnings when
building pcic.c as well as the undefined functions when the kernel
links.

beef8a367c This solves a deadlock that can occur when read()ing into a file-mmap()
space. When doing this, it is possible to for another process to attempt
to get an exclusive lock on the vnode and deadlock the mmap/read
combination when the uiomove() call tries to obtain a second
shared lock on the vnode. There is still a potential deadlock
situation with write()/mmap().

Submitted by:	Matt Dillon <dillon@frebsd.org>

This change implements a relatively sophisticated fix to getnewbuf().
There were two problems with getnewbuf(). First, the writerecursion
can lead to a system stack overflow when you have NFS and/or VN
devices in the system. Second, the free/dirty buffer accounting was
completely broken. Not only did the nfs routines blow it trying to
manually account for the buffer state, but the accounting that was
done did not work well with the purpose of their existance: figuring
out when getnewbuf() needs to sleep.

The meat of the change is to kern/vfs_bio.c. The remaining diffs are
all minor except for NFS, which includes both the fixes for bp
interaction AND fixes for a 'biodone(): buffer already done' lockup.
Sys/buf.h also contains a chaining structure which is not used by
this patchset but is used by other patches that are coming soon.
This patch deliniated by tags PRE_MAT_GETBUF and POST_MAT_GETBUF.

56ce1a8dc4 Fixed runtime accounting. The time since the previous context switch
was discarded on every call to calcru().  Hacking on the `switchtime'
global for a related fix in rev.1.38 of kern_resource.c was too fragile

e9deda23ae Keyboard driver update in preparation for the USB keyboard driver.
- Refined internal interface in keyboard drivers so that:
  1. the side effect of device probe is kept minimal,
  2. polling mode function is added,
  3. and new ioctl and configuration options are added (see below).

- Added new ioctl: KDSETREPEAT
  Set keyboard typematic rate.  There has existed an ioctl command,
  KDSETRAD, for the same purpose.  However, KDSETRAD is dependent on
  the AT keyboard.  KDSETREPEAT provides more generic interface.
  KDSETRAD will still be supported in the atkbd driver.

- Added new configuration options:
  ATKBD_DFLT_KEYMAP
  Specify a keymap to be used as the default, built-in keymap.
  (There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
  SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.
  These options are now gone for good.  The new option is more general.)

  KBD_DISABLE_KEYMAP_LOADING
  Don't allow the user to change the keymap.

1853e64dca Fix from author of the driver:
The i++ loop from 1..1000 is too small on very fast machines like
PII 450 MHz. Increasing the loop from 1..100000 lets the machine
access PHY. After this patch it's possible to use a SMC PCI card
on a HP Kayak XA series PC Workstation. Workaround until this fix
was to enable debugging in the driver (#define EPIC_DEBUG 1).

Without that patch you get an undefined state:
while true
do
ifconfig -a | grep status:
done
The status messages flaps between twwo values, but not
"connected".

08c9325cb2 Fix a number of memory leaks and other memory-related disorders.
Also, unbreak the breakage introduced at the last revision of module.c.
This changes the semantics of mod_searchfile() (and mod_searchmodule())
to make the caller's responsibility freeing the buffer returned. This
is different from other functions in loader's code, and was done as a
fix for kern/9631. If someone wants to revert this to the original
behavior, don't forget to fix kern/9631 in another way.

This should also fix bin/10462, which was introduced as a result of the
first try at kern/9631 (module.c last revision).
