ae9fcf4c66 Remove test in pipe_write() which causes write(2) to return EAGAIN
on a non-blocking pipe in cases where select(2) returns the file
descriptor as ready for write. This in turns causes libc_r, for
one, to busy wait in such cases.

Note: it is a quick performance fix, a more complex fix might be
required in case this turns out to have unexpected side effects.

1734c95cec Fixed style bugs in rev.1.94 before MFCing it (for large C asm statements,
use "\n\" instead of "\" at the end of each source line, and don't use
semicolons).  Fixed some older style bugs on the same lines (mainly
English errors in comments).

d56368d779 Plug a race and a leak in UMA.
1) The race has to do with zone destruction.  From the zone destructor we
   would lock the zone, set the working set size to 0, then unlock the zone,
   drain it, and then free the structure.  Within the window following the
   working-set-size set to 0 and unlocking of the zone and the point where
   in zone_drain we re-acquire the zone lock, the uma timer routine could
   have fired off and changed the working set size to something non-zero,
   thereby potentially preventing us from completely freeing slabs before
   destroying the zone (and thus leaking them).

2) The leak has to do with zone destruction as well.  When destroying a
   zone we would take care to free all the buckets cached in the zone, but
   although we would drain the pcpu cache buckets, we would not free them.
   This resulted in leaking a couple of bucket structures (512 bytes each)
   per cpu on SMP during zone destruction.

While I'm here, also silence GCC warnings by turning uma_slab_alloc()
from inline to real function.  It's too big to be an inline.

93b4c5b707 The introduction of vm object locking has caused witness to reveal
a long-standing mistake in the way a portion of a pipe's KVA is
allocated.  Specifically, kmem_alloc_pageable() is inappropriate
for use in the "direct" case because it allows a preceding vm map entry
and vm object to be extended to support the new KVA allocation.
However, the direct case KVA allocation should not have a backing
vm object.  This is corrected by using kmem_alloc_nofault().

416c84a212 Return 1 from pmap_protect_tte() instead of 0. When used with
tsb_foreach(), 0 signals to terminate the tsb traversal, so when
tsb_foreach() was used in pmap_protect() (which only happens when
the area to be protected is larger than PMAP_TSB_THRESH = 16MB), only
the first tsb entry in the specified range would be protected.

a40fdcb439 When generating the zone stats make sure to handle the master zone
("UMA Zone") carefully, because it does not have pcpu caches allocated
at all.  In the UP case, we did not catch this because one pcpu cache
is always allocated with the zone, but for the MP case, we were getting
bogus stats for this zone.

9b72ad91bf Initialize the FIXCRYPTO, BINMAKE and related variables (that use
the != operator) only when needed.

This change allows me to check out the current version of release/
makefiles only (co -l) to /tmp/release, and use that directory to
build a release (supplying the correct WORLDDIR).

Without this, attempt to "make release" caused an endless fork bomb
while trying to evaluate FIXCRYPTO, and the only way I could get
away from this on a remote box was to "kill -INT 1", thanks to
tcsh(1) and its internal "kill" command.

d11e0ba565 - Check to see if we need a slab prior to allocating one. Failure to do
so not only wastes memory but it can also cause a leak in zones that
   will be destroyed later.  The problem is that the slab allocation code
   places newly created slabs on the partially allocated list because it
   assumes that the caller will actually allocate some memory from it.
   Failure to do so places an otherwise free slab on the partial slab list
   where we wont find it later in zone_drain().

f52ecc3346 Restored clearing of the bss, except for putting it in a correct place
with up to date comments.  This fixes booting kernels with boot2
(except for loss of the features provided by loader) and is suitable
for MFC.  Contrary to the old comments, most loaders don't clear the bss.
biosboot lost clearing of the bss in a code crunch in 1997, and boot2
never did it.

kan didn't notice the problem with gcc-3.3 putting variables that are
initialized to 0 in the bss until after committing gcc-3.3 because he
was already using essentially this patch.  Before gcc-3.3, only the
non-critical `bootdev' variable was clobbered by clearing the bss.
