NFS_MINATTRTIMO         VREG attrib cache timeout in sec
NFS_MAXATTRTIMO
NFS_MINDIRATTRTIMO      VDIR attrib cache timeout in sec
NFS_MAXDIRATTRTIMO
NFS_GATHERDELAY         Default write gather delay (msec)
NFS_UIDHASHSIZ          Tune the size of nfssvc_sock with this
NFS_WDELAYHASHSIZ       and with this
NFS_MUIDHASHSIZ         Tune the size of nfsmount with this
NFS_NOSERVER            (already documented in LINT)
NFS_DEBUG               turn on NFS debugging

also, because NFS_ROOT is used by very different files, it has been
renamed to opt_nfsroot.h instead of the old opt_nfs.h....

7645c57470 Converted add_interrupt_randomness() to take a `void *' arg. Rewrote
mmioctl() to fix hundreds of style bugs and a few error handling bugs
(don't check for superuser privilege for inappropriate ioctls, don't
check the input arg for the output-only MEM_RETURNIRQ ioctl, and don't
return EPERM for null changes).

939eba4d19 Don't declare isa device structs or isa interrupt handlers in <sys/conf>,
and don't depend on them being declared there.  This will cause lots of
warnings for a few minutes until config is updated.  Interrupt handlers
should never have been configured by config, and the machine generated
declarations get in the way of changing the arg type from int to void *.

dbddecf49e Pass lists of possible root devices and their names up to the
machine-independent code and try mounting the devices in the
lists instead of guessing alternative root devices in a machine-
dependent way.

autoconf.c:
Reject preposterous slice numbers instead of silently converting
them to COMPATIBILITY_SLICE.

Don't forget to force slice = COMPATIBILITY_SLICE in the floppy
device name.

Eliminated most magic numbers and magic device names in setroot().

Fixed dozens of style bugs.

vfs_conf.c:
Put the actual root device name instead of "root_device" in the
mount struct if the actual name is available.  This is useful after
booting with -s.  If it were set in all cases then it could be used
to do mount(8)'s ROOTSLICE_HUNT and fsck(8)'s hotroot guess better.

1d5f38ac22 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

d3d65c6b2e Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.
Clean up (or if antipodic: down) some of the msgbuf stuff.

Use an inline function rather than a macro for timecounter delta.

Maintain process "on-cpu" time as 64 bits of microseconds to avoid
needless second rollover overhead.

Avoid calling microuptime the second time in mi_switch() if we do
not pass through _idle in cpu_switch()

This should reduce our context-switch overhead a bit, in particular
on pre-P5 and SMP systems.

WARNING:  Programs which muck about with struct proc in userland
will have to be fixed.

a4775d632f Missing parens caused cpu features not to be printed for cyrix >= M2/MX.
Althought the comments say the datasheet doesn't list the device ID
registers on the M2/MX, they seem to be there and quite alive.
(It's interesting to note that the M2/MX calls itself a 686 class cpu but
 is missing a heck of a lot of features, including VME, PGE, PSE, etc)

cf73abacf6 Change simple lock handling to not depend upon having a local apic
available.  The per-cpu variable ss_tpr has been replaced by ss_eflags.
This reduced the number of interrupts sent to the wrong CPU, due to
the cpu having the global lock being inside a critical region.

Remove some unneeded manipulation of tpr register in mplock.s.

Adjust code in mplock.s to be aware of variables on the stack being
destroyed by MPgetlock if GRAB_LOPRIO is defined.

4347025be3 Add forwarding of roundrobin to other cpus. This gives a more regular
update of cpu usage as shown by top when one process is cpu bound
(no system calls) while the system is otherwise idle (except for top).

Don't attempt to switch to the BSP in boot().  If the system was idle when
an interrupt caused a panic, this won't work.  Instead, switch to the BSP
in cpu_reset.

Remove some spurious forward_statclock/forward_hardclock warnings.

ec73ba31ec Some of newer PC-98 may cause "Windows Protection Fault" when booting
Windows 95 after rebooting FreeBSD without power off.  In PC-98
system, reboot mode is set via I/O port 0x37 in cpu_reset(), and
accessing of this port is the reason of the problem.  To avnoid the
fault, current status of reboot mode should be checked before
accessing the I/O port.

53cc68b743 Backed out previous commit. It is invalid to call d_ioctl() on
possibly non-open devices, and we don't want to restrict dumping
to swap devices anwyay.  It is especially invalid to call d_ioctl()
in non-process context for panics.  d_psize() can be called on
non-open devices, at least on non-SLICED ones that support d_dump(),
and setdumpdev() has depended on this for a long time although it
is probably wrong, but even d_psize() can't be called in non-process
context - that's why dumpsys() depends on previously computed values
although these values may be stale.  The historical restriction to
devices with dkpart(dev) == SWAP_PART should go away.
