d7ed4e7b79 Try to avoid crashes during kernel startup by limiting the # of EISA
slots to probe.  Problems have been reported in this area, lets hope this
bandaid helps.

!! Owners of EISA-equipped Alpha machines are requested to at least
!! boot-test a 6-BETA build and report back to the Alpha list. Thanks!

---snip---
FYI this bit isn't needed for FreeBSD - I think it came from either
OpenBSD or NetBSD where arc4random() wasn't available during cold
boot.

e515ee7832 Make rule zero really magical, that way we don't have to do anything
when we mount and get zero cost if no rules are used in a mountpoint.

Add code to deref rules on unmount.

Switch from SLIST to TAILQ.

Drop SYSINIT, use SX_SYSINIT and static initializer of TAILQ instead.

Drop goto, a break will do.

Reduce double pointers to single pointers.

Combine reaping and destroying rulesets.

Avoid memory leaks in a some error cases.

0e4f6eecd7 Restore a historical ufs_inactive behavior that has been changed
in rev. 1.40 of ufs_inode.c, which allows an inode being truncated
even when the filesystem itself is marked RDONLY.  A subsequent
call of UFS_TRUNCATE (ffs_truncate) would panic the system as it
asserts that it can only be called when the filesystem is mounted
read-write (same changeset, rev. 1.74 of sys/ufs/ffs/ffs_inode.c).

Because ffs_mount() already takes care of sync'ing the filesystem
to disk before being downgraded to readonly, it appears to be more
desirable that we should not permit this sort of writes to disk.

This change would fix a panic that occours when read-only mounted
a corrupted filesystem and doing some file operations.

It confuses the lock manager since in some places thread0 is

7028887eac Add fi_sx, an sx lock to serialize I/O operations on the socket pair
underlying the POSIX fifo implementation.  In 6.x/7.x, fifo access is
moved from the VFS layer, where it was serialized using the vnode
lock, to the file descriptor layer, where access is protected by a
reference count but not serialized.  This exposed socket buffer
locking to high levels of parallelism in specific fifo workloads, such
as make -j 32, which expose as yet unresolved socket buffer bugs.

fi_sx re-adds serialization about the read and write routines,
although not paths that simply test socket buffer mbuf queue state,
such as the poll and kqueue methods.  This restores the extra locking
cost previously present in some cases, but is an effective workaround
for the instability that has been experienced.  This workaround should
be removed once the bug in socket buffer handling has been fixed.

has been removed.  It has been replaced by hw.pci.do_power_nodriver
and hw.pci.do_power_resume.  The former defaults to 0 while the latter
defaults to 1.

When do_powerstate was set to 0, it broke suspend/resume for a lot of
people as an unintended consequence.  This change will only affect the
areas that were intended to affect.  This change will have no effect on

2d7e9ead07 Several fixes to rt_setgate(), that fix problems with route changing:
- Rearrange code so that in a case of failure the affected
  route is not changed. Otherwise, a bogus rtentry will be
  left and later rt_check() can recurse on its lock. [1]
- Remove comment about protocol cloning.
- Fix two places where rtentry mutex was recursed on, because
  accessed via two different pointers, that were actually pointing
  to the same rtentry in some cases. [1]
- Return EADDRINUSE instead of bogus EDQUOT, in case when gateway
  uses the same route. [2]
