6660f1d7c1 Serialize access to the info/dir file; needed for parallel installs.
Reported by:	scottl

I'm not very fond of using the non-standard lockf(1) here, but I
have no better idea at the moment.  NetBSD uses ln(1) to create a
lock file, but this approach can result in a deadlock if make is
interrupted, leaving an orphaned lock file.

41ce2892bb In nfs_flush(), clear the NMODIFIED bit only if there are no dirty
buffers *and* there are no buffers queued up for writing.  The bug
was that NMODIFIED was being cleared even while there were buffers
scheduled to be written out, which leads to all sorts of interesting
bugs - one where the file could shrink (because of a post-op getattr
load, say) causing data in buffer(s) queued for write to be tossed,
resulting in data corruption.

c7362ff7fb Change the x86 code to allocate IDT vectors on-demand when an interrupt
source is first enabled similar to how intr_event's now allocate ithreads
on-demand.  Previously, we would map IDT vectors 1:1 to IRQs.  Since we
only have 191 available IDT vectors for I/O interrupts, this limited us
to only supporting IRQs 0-190 corresponding to the first 190 I/O APIC
intpins.  On many machines, however, each PCI-X bus has its own APIC even
though it only has 1 or 2 devices, thus, we were reserving between 24 and
32 IRQs just for 1 or 2 devices and thus 24 or 32 IDT vectors.  With this
change, a machine with 100 IRQs but only 5 in use will only use up 5 IDT
vectors.  Also, this change provides an API (apic_alloc_vector() and
apic_free_vector()) that will allow a future MSI interrupt source driver to
request IDT vectors for use by MSI interrupts on x86 machines.

a91395a9d0 Tests with my dual Opteron system have shown that it's possible
for code to start out on one CPU when thunking into Windows
mode in ctxsw_utow(), and then be pre-empted and migrated to another
CPU before thunking back to UNIX mode in ctxsw_wtou(). This is
bad, because then we can end up looking at the wrong 'thread environment
block' when trying to come back to UNIX mode. To avoid this, we now
pin ourselves to the current CPU when thunking into Windows code.

Few other cleanups, since I'm here:

- Get rid of the ndis_isr(), ndis_enable_interrupt() and
  ndis_disable_interrupt() wrappers from kern_ndis.c and just invoke
  the miniport's methods directly in the interrupt handling routines
  in subr_ndis.c. We may as well lose the function call overhead,
  since we don't need to export these things outside of ndis.ko
  now anyway.

- Remove call to ndis_enable_interrupt() from ndis_init() in if_ndis.c.
  We don't need to do it there anyway (the miniport init routine handles
  it, if needed).

- Fix the logic in NdisWriteErrorLogEntry() a little.

- Change some NDIS_STATUS_xxx codes in subr_ntoskrnl.c into STATUS_xxx
  codes.

- Handle kthread_create() failure correctly in PsCreateSystemThread().

56a4e45ab3 Mandatory mbuf cluster reference counting and groundwork for UMA
based jumbo 9k and jumbo 16k cluster support.

All mbuf's with external storage attached are mandatory reference
counted.  For clusters and jumbo clusters UMA provides the refcnt
storage directly.  It does not have to be separatly allocated.  Any
other type of external storage gets its own refcnt allocated from
an UMA mbuf refcnt zone instead of normal kernel malloc.

The refcount API MEXT_ADD_REF() and MEXT_REM_REF() is no longer
publically accessible.  The proper m_* functions have to be used.

mb_ctor_clust() and mb_dtor_clust() both handle normal 2K as well
as 9k and 16k clusters.

Clusters and jumbo clusters may be obtained without attaching it
immideatly to an mbuf.  This is for high performance cluster
allocation in network drivers where mbufs are attached after the
cluster has been filled.

cb92d4d58f Moved the optimization for tiny x from __kernel_tan[f](x) to tan[f](x)
so that it can be faster for tiny x and avoided for reduced x.

This improves things a little differently than for cosine and sine.
We still need to reclassify x in the "kernel" functions, but we get
an extra optimization for tiny x, and an overall optimization since
tiny reduced x rarely happens.  We also get optimizations for space
and style.  A large block of poorly duplicated code to fix a special
case is no longer needed.  This supersedes the fixes in k_sin.c revs
1.9 and 1.11 and k_sinf.c 1.8 and 1.10.

Fixed wrong constant for the cutoff for "tiny" in tanf().  It was
2**-28, but should be almost the same as the cutoff in sinf() (2**-12).
The incorrect cutoff protected us from the bugs fixed in k_sinf.c 1.8
and 1.10, except 4 cases of reduced args passed the cutoff and needed
special handling in theory although not in practice.  Now we essentially
use a cutoff of 0 for the case of reduced args, so we now have 0 special
args instead of 4.

This change makes no difference to the results for sinf() (since it
only changes the algorithm for the 4 special args and the results for
those happen not to change), but it changes lots of results for sin().
Exhaustive testing is impossible for sin(), but exhaustive testing
for sinf() (relative to a version with the old algorithm and a fixed
cutoff) shows that the changes in the error are either reductions or
from 0.5-epsilon ulps to 0.5+epsilon ulps.  The new method just uses
some extra terms in approximations so it tends to give more accurate
results, and there are apparently no problems from having extra
accuracy.  On amd64 with -O1, on all float args the error range in ulps
is reduced from (0.500, 0.665] to [0.335, 0.500) in 24168 cases and
increased from 0.500-epsilon to 0.500+epsilon in 24 cases.  Non-
exhaustive testing by ucbtest shows no differences.

34333b16cd Retire MT_HEADER mbuf type and change its users to use MT_DATA.
Having an additional MT_HEADER mbuf type is superfluous and redundant
as nothing depends on it.  It only adds a layer of confusion.  The
distinction between header mbuf's and data mbuf's is solely done
through the m->m_flags M_PKTHDR flag.

Non-native code is not changed in this commit.  For compatibility
MT_HEADER is mapped to MT_DATA.

4f8d68d6ca Updated the comment about the optimization for tiny x (the previous
commit moved it).  This includes a comment that the "kernel" sine no
longer works on arg -0, so callers must now handle this case.  The kernel
sine still works on all other tiny args; without the optimization it is
just a little slower on these args.  I intended it to keep working on
all tiny args, but that seems to be impossible without losing efficiency
or accuracy.  (sin(x) ~ x * (1 + S1*x**2 + ...) would preserve -0, but
the approximation must be written as x + S1*x**3 + ... for accuracy.)

639a1e1106 Removed dead code for handling tan[f]() on odd multiples of pi/2. This
case never occurs since pi/2 is irrational so no multiple of it can
be represented as a float and we have precise arg reduction so we never
end up with a remainder of 0 in the "kernel" function unless the
original arg is 0.

If this case occurs, then we would now fall through to general code
that returns +-Inf (depending on the sign of the reduced arg) instead
of forcing +Inf.  The correct handling would be to return NaN since
we would have lost so much precision that the correct result can be
anything _except_ +-Inf.

Don't reindent the else clause left over from this, although it was already
bogusly indented ("if (foo) return; else ..." just marches the indentation
to the right), since it will be removed too.

16622bffd4 Fixed some of the silliness related to rev.1.8. In 1.8, "double" in
a declaration was not translated to "float" although bit fiddling on
double variables was translated.  This resulted in garbage being put
into the low word of one of the doubles instead of non-garbage being
put into the only word of the intended float.  This had no effect on
any result because:
- with doubles, the algorithm for calculating -1/(x+y) is unnecessarily
  complicated.  Just returning -1/((double)x+y) would work, and the
  misdeclaration gave something like that except for messing up some
  low bits with the bit fiddling.
- doubles have plenty of bits to spare so messing up some of the low
  bits is unlikely to matter.
- due to other bugs, the buggy code is reached for a whole 4 args out
  of all 2**32 float args.  The bug fixed by 1.8 only affects a small
  percentage of cases and a small percentage of 4 is 0.  The 4 args
  happen to cause no problems without 1.8, so they are even less likely
  to be affected by the bug in 1.8 than average args; in fact, neither
  1.8 nor this commit makes any difference to the result for these 4
  args (and thus for all args).

Corrections to the log message in 1.8: the bug only applies to tan()
and not tanf(), not because the float type can't represent numbers
large enough to trigger the problem (e.g., the example in the fdlibm-5.3
readme which is > 1.0e269), but because:
- the float type can't represent small enough numbers.  For there to be
  a possible problem, the original arg for tanf() must lie very near an
  odd multiple of pi/2.  Doubles can get nearer in absolute units.  In
  ulps there should be little difference, but ...
- ... the cutoff for "small" numbers is bogus in k_tanf.c.  It is still
  the double value (2**-28).  Since this is 32 times smaller than
  FLT_EPSILON and large float values are not very uniformly distributed,
  only 6 args other than ones that are initially below the cutoff give
  a reduced arg that passes the cutoff (the 4 problem cases mentioned
  above and 2 non-problem cases).

Fixing the cutoff makes the bug affect tanf() and much easier to detect
than for tan().  With a cutoff of 2**-12 on amd64 with -O1, 670102
args pass the cutoff; of these, there are 337604 cases where there
might be an error of >= 1 ulp and 5826 cases where there is such an
error; the maximum error is 1.5382 ulps.

The fix in 1.8 works with the reduced cutoff in all cases despite the
bug in it.  It changes the result in 84492 cases altogether to fix the
5826 broken cases.  Fixing the fix by translating "double" to "float"
changes the result in 42 cases relative to 1.8.  In 24 cases the
(absolute) error is increased and in 18 cases it is reduced, but it
remains less than 1 ulp in all cases.
