6e5f3d0f0f Allow the user tsb to span multiple pages. Make the default 2 pages for now
until we do some testing to see what's best.  This gives a massive reduction
in system time for processes with a relatively large working set.  The size
of the tsb directly affects the rss size that a user process can keep mapped.
When it starts to get full replacements occur and the process takes a lot of
soft vm faults.  Increasing the default from 1 page to 2 gives the following
before and after numbers for compiling vfs_bio.c:

before:
       14.27 real         6.56 user         5.69 sys
after:
        8.57 real         6.11 user         1.62 sys

This should make self hosted builds more tolerable.

6bd95d70db Work-in-progress commit syncing up pmap cleanups that I have been working
on for a while:
- fine grained TLB shootdown for SMP on i386
- ranged TLB shootdowns.. eg: specify a range of pages to shoot down with
  a single IPI, since the IPI is very expensive.  Adjust some callers
  that used to trigger this inside tight loops to do a ranged shootdown
  at the end instead.
- PG_G support for SMP on i386 (options ENABLE_PG_G)
- defer PG_G activation till after we decide what we are going to do with
  PSE and the 4MB pages at the start of the kernel.  This should solve
  some rumored strangeness about stale PG_G entries getting stuck
  underneath the 4MB pages.
- add some instrumentation for the fine TLB shootdown
- convert some asm instruction wrappers from functions to inlines.  gcc
  seems to do a fair bit better with this.
- [temporarily!] pessimize the tlb shootdown IPI handlers.  I will fix
  this again shortly.

This has been working fairly well for me for a while, but I have tweaked
it again prior to commit since my last major testing round.  The only
outstanding problem that I know of is PG_G related, which is why there
is an option for it (not on by default for SMP).  I have seen a world
speedups by a few percent (as much as 4 or 5% in one case) but I have
*not* accurately measured this - I am a bit sceptical of these numbers.

yet -- things aren't just quite ready (but almost).  So this commit should
be OK to make.

2faccca61a Turn on -Werror by default. This is is easily turned off, by either:
- fix the warnings, they are there for a reason!
- add -DNO_ERROR to your make(1) command.
- add 'makeoptions NO_WERROR=true' to your kernel config.
- add 'nowerror' to conf/files* that have warnings that should be fixed
  due to tracking 3rd party vendor code.
- add 'nowerror' to conf/files* where the warning is false due to a
  compiler bug and fixing it with brute force would be too expensive.

There are some very sloppy warnings in our kernel build, come on folks!

'make release' uses -DNO_WERROR intentionally.

4c4a1a19e8 Implement a nested window state. This avoids attempting to spill a user
window to the user stack while in a nested kernel trap.  We do this for
entry to the kernel from user mode, but if we get an interrupt in kernel
mode while there are still user windows in the cpu, and we attempt to spill
to the user stack, we may take too many nested traps and overflow the trap
stack, causing a red state exception.  This is needed by upcoming changes
to allow the user tsb to not be locked in the tlb.

cb877d0050 Add a new test_counter() function which tries to determine the width of
the inter-value histogram for 2000 samples.  If the width is 3 or less
for 10 consequtive samples, we trust the counter to be good, otherwise
we use the *_safe() method.

This method may be too strict, but the worst which can happen is that
we take the performance hit of the *_safe() method when we should not.

Make the *_safe() method more discriminating by mandating that the three
samples do not span more than 15 ticks on the counter.

Disable the PCI-ident based probing as a means to recognize good
counters.

2ca2159f22 The TCP code did not do sufficient checks on whether incoming packets
were destined for a broadcast IP address. All TCP packets with a
broadcast destination must be ignored. The system only ignored packets
that were _link-layer_ broadcasts or multicast. We need to check the
IP address too since it is quite possible for a broadcast IP address
to come in with a unicast link-layer address.

Note that the check existed prior to CSRG revision 7.35, but was
removed. This commit effectively backs out that nine-year-old change.

3c997c536c Modify the tte format to not include the tlb context number and to store the
virtual page number in a much more convenient way; all in one piece.  This
greatly simplifies the comparison for a matching tte, and allows the fault
handlers to be much simpler due to not having to load wierd masks.
Rewrite the tlb fault handlers to account for the new format.  These are also
written to allow faults on the user tsb inside of the fault handlers; the
kernel fault handler must be aware of this and not clobber the other's
registers.  The faults do not yet occur due to other support that is needed
(and still under my desk).

0c6ec4aca0 Declare time(not3) instead of depending on namespace pollution 3 layers
deep in <stand.h> to eventually include <time.h> to declare the user
version.

This is not quite the right place to declare it, but <stand.h> would
be worse because time() is very MD so it isn't in libstand.

Many places in the boot sources still get the user version using only
1 layer of pollution (#include <sys/time.h>.  Some pollute themselves
directly (#include <time.h>).  But the boot Makefiles are too broken
to enable warnings for redeclarations.

ddb7d629f1 Sockets passed into uipc_abort() have been allocated by sonewconn()
but never accept'ed, so they must be destroyed. Originally, unp_drop()
detected this situation by checking if so->so_head is non-NULL.
However, since revision 1.54 of uipc_socket.c (Feb 1999), so->so_head
is set to NULL before calling soabort(), so any unix-domain sockets
waiting to be accept'ed are leaked if the server socket is closed.

Resolve this by moving the socket destruction code into uipc_abort()
itself, and making it unconditional (the other caller of unp_drop()
never needs the socket to be destroyed). Use unp_detach() to avoid
the original code duplication when destroying the socket.

d32e27a9f4 Tests by numerous people have shown that many chipsets do not properly
latch the acpi timer, resulting in weird deltas.  The problem is severe
enough to adversely effect the timecounter code.

Default to the 'safe' version of the get-timecount function.  The probe
will override it if a known-good chipset is found.  This is temporary
until a more complete solution is found.
