dd540b4623 Add a parser for the ACPI SRAT table for amd64 and i386. It sets
PCPU(domain) for each CPU and populates a mem_affinity array suitable
for the NUMA support in the physical memory allocator.

d8561f0a50 Update mlockall(2) to mention that it's superuser-only syscall, just
like the mlock(2) manual page says.  Update mlock(2) to say that hitting
RLIMIT_MEMLOCK results in ENOMEM, not EAGAIN.

a3870a1826 Very rough first cut at NUMA support for the physical page allocator. For
now it uses a very dumb first-touch allocation policy.  This will change in
the future.
- Each architecture indicates the maximum number of supported memory domains
  via a new VM_NDOMAIN parameter in <machine/vmparam.h>.
- Each cpu now has a PCPU_GET(domain) member to indicate the memory domain
  a CPU belongs to.  Domain values are dense and numbered from 0.
- When a platform supports multiple domains, the default freelist
  (VM_FREELIST_DEFAULT) is split up into N freelists, one for each domain.
  The MD code is required to populate an array of mem_affinity structures.
  Each entry in the array defines a range of memory (start and end) and a
  domain for the range.  Multiple entries may be present for a single
  domain.  The list is terminated by an entry where all fields are zero.
  This array of structures is used to split up phys_avail[] regions that
  fall in VM_FREELIST_DEFAULT into per-domain freelists.
- Each memory domain has a separate lookup-array of freelists that is
  used when fulfulling a physical memory allocation.  Right now the
  per-domain freelists are listed in a round-robin order for each domain.
  In the future a table such as the ACPI SLIT table may be used to order
  the per-domain lookup lists based on the penalty for each memory domain
  relative to a specific domain.  The lookup lists may be examined via a
  new vm.phys.lookup_lists sysctl.
- The first-touch policy is implemented by using PCPU_GET(domain) to
  pick a lookup list when allocating memory.

2af6e14d39 Introduce exec_alloc_args(). The objective being to encapsulate the
details of the string buffer allocation in one place.

Eliminate the portion of the string buffer that was dedicated to storing
the interpreter name.  The pointer to the interpreter name can simply be
made to point to the appropriate argument string.

fa597729aa Document that the "ngtee" action no longer accepts packet, and
thus don't depend on one_pass flag anymore.

This is a POLA violation, but it is quite difficult to restore
the old behavior with new code. Also, the new behavior matches
behavior of the older "tee" action, and this is more intuitive.

85011246ac When installing a new ARP entry via 'arp -S', lla_lookup() will
either find an existing entry, or allocate a new one. In the latter
case an entry would have flags, that were supplied as argument to
lla_lookup(). In case of an existing entry, flags aren't modified.

This lead to losing LLE_PUB and/or LLE_PROXY flags.

We should apply these flags either in lla_rt_output() or in the
in.c:in_lltable_lookup(). It seems to me that lla_rt_output() is
a more correct choice.

6c0c240366 sh: Fix crash due to uninitialized here-document.
If an ; or & token was followed by an EOF token, pending here-documents were
left uninitialized. Execution would crash, either in the main shell process
for literal here-documents or in a child process for expanded
here-documents. In the latter case the problem is hard to detect apart from
the core dumps and log messages.

Side effect: slightly different retries on inputs where EOF is not
persistent.

Note that tools/regression/bin/sh/parser/heredoc6.0 still causes a similar
crash in a child process. The text passed to eval is malformed and should be
rejected.

9e4e511499 Change the order in which the file name, arguments, environment, and
shell command are stored in exec*()'s demand-paged string buffer.  For
a "buildworld" on an 8GB amd64 multiprocessor, the new order reduces
the number of global TLB shootdowns by 31%.  It also eliminates about
330k page faults on the kernel address space.

Change exec_shell_imgact() to use "args->begin_argv" consistently as
the start of the argument and environment strings.  Previously, it
would sometimes use "args->buf", which is the start of the overall
buffer, but no longer the start of the argument and environment
strings.  While I'm here, eliminate unnecessary passing of "&length"
to copystr(), where we don't actually care about the length of the
copied string.

Clean up the initialization of the exec map.  In particular, use the
correct size for an entry, and express that size in the same way that
is used when an entry is allocated.  The old size was one page too
large.  (This discrepancy originated in 2004 when I rewrote
exec_map_first_page() to use sf_buf_alloc() instead of the exec map
for mapping the first page of the executable.)
