Fix a deadlock between a route update and lltable
It happens because rtalloc1 is called from lltable with holding
IF_AFDATA_WLOCK.
If a route update is in action, rtalloc1 would wait for its completion with
holding IF_AFDATA_WLOCK. At the same moment, a softint (e.g., arpintr) may try
to take IF_AFDATA_WLOCK and get stuck on it. Unfortunately the stuck softint
prevents the route update from progressing because the route update calls
psref_target_destroy that needs the softint to complete.
A resource allocation graph of the senario looks like this:
    route update =(psref_target_destroy)=> softint => IF_AFDATA_WLOCK
    =(rt_update_wait)=> route update
Fix the deadlock by pulling rtalloc1 out of the lltable codes inside
IF_AFDATA_WLOCK.
Note that the deadlock happens only if NET_MPSAFE is enabled.

bin/sh/jobs.c: revision 1.91 (patch)

PR bin/52640  PR bin/52641

Don't delete jobs from the jobs table merely because they finished,
if they are not the job we are waiting upon.  (bin/52640 part 1)

In a sub-shell environment, don't allow wait to find jobs from the
parent shell that had already exited (before the sub-shell was
created) and return status for them as if they are our children.
(bin/52640 part 2)

Don't have the "jobs" command also be an implicit "wait" command
in non-interactive shells.  (bin/52641)

Use WCONTINUED (when it exists) so we can report on stopped jobs that
"mysteriously" move back to running state without the user issuing
a "bg" command (eg: kill -CONT <pid>)  Previously they would keep
being reported as stopped until they exited.
When a job is detected as having changed status just as we're
issuing a "jobs" command (i.e.: the change occurred between the last
prompt and the jobs command being entered) don't report it twice,
once from the status change, and then again in the jobs command
output.  Once is enough (keep the jobs output, suppress the other).

Apply some sanity to the way jobs_invalid is processed - ignore it
in getjob() instead of just ignoring it most of the time there, and
instead always check it before calling getjob() in situations where
we can handle only children of the current shell.  This allows the
(totally broken) save/clear/restore of jobs_invalid in jobscmd() to
be done away with (previously an error while in the clear state would
have left jobs_invalid incorrectly cleared - shouldn't have mattered
since jobs_invalid => subshell => error causes exit, but better to be safe).

Implement a debugging facility (overflow/underflow detection) for localcount

We cannot get an accurate count from a localcount instance because it consists
of per-cpu counters and we have no way to sum them up atomically. So we cannot
detect counter overflow/underflow as we can do on a normal refcount.

The facility adds an atomic counter to each localcount instance to enable the
validations. The counter ups and downs in synchronization with the per-CPU
counters. The counter is used iff both DEBUG and LOCKDEBUG are enabled in the
kernel.

Unify IFEF_*_MPSAFE into IFEF_MPSAFE

There are already two flags for if_output and if_start, however, it seems such
MPSAFE flags are eventually needed for all if_XXX operations. Having discrete
flags for each operation is wasteful of if_extflags bits. So let's unify
the flags into one: IFEF_MPSAFE.

Fortunately IFEF_*_MPSAFE flags have never been included in any releases, so
we can change them without breaking backward compatibility of the releases
(though the kernel version of -current should be bumped).

Note that if an interface have both MP-safe and non-MP-safe operations at a
time, we have to set the IFEF_MPSAFE flag and let callees of non-MP-safe
opeartions take the kernel lock.

Support large pages on KASLR kernels, in a way that does not reduce
randomness, but on the contrary that increases it.

The size of the kernel sub-blocks is changed to be 1MB. This produces a
kernel with sections that are always < 2MB in size, that can fit a large
page.

Each section is put in a 2MB physical chunk. In this chunk, there is a
padding of approximately 1MB. The prekern uses a random offset aligned to
sh_addralign, to shift the section in physical memory.

For example, physical memory layout created by the bootloader for .text.4
and .rodata.0:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+
|+---------------+                  |+---------------+                  |
||    .text.4    |      PAD        ||  .rodata.0  |      PAD        |
|+---------------+                  |+---------------+                  |
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+
PA                                  PA+2MB                        PA+4MB

Then, physical memory layout, after having been shifted by the prekern:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+
| P +---------------+              |          +---------------+        |
| A |    .text.4    |      PAD      |  PAD    |  .rodata.0  |  PAD  |
| D +---------------+              |          +---------------+        |
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+
PA                                  PA+2MB                        PA+4MB

The kernel maps these 2MB physical chunks with 2MB large pages. Therefore,
randomness is enforced at both the virtual and physical levels, and the
resulting entropy is higher than that of our current implementaion until
now.

The padding around the section is filled by the prekern. Not to consume
too much memory, the sections that are smaller than PAGE_SIZE are mapped
with normal pages - because there is no point in optimizing them. In these
normal pages, the same shift is applied.

This change has two additional advantages: (a) the cache attacks based on
the TLB are mostly mitigated, because even if you are able to determine
that a given page-aligned range is mapped as executable you don't know
where exactly within that range the section actually begins, and (b) given
that we are slightly randomizing the physical layout we are making some
rare physical attacks more difficult to conduct.

NOTE: after this change you need to update GENERIC_KASLR / prekern /
bootloader.

Put back /bin/cp and /sbin/sysctl to installation binaries.

Split each kernel section into sub-blocks of approximately 2MB. The newly
created sections are named .origname.i, for example:

.text -> { .text .text.0 .text.1 .text.2 .text.3 .text.4 }

Each section is randomized independently by the prekern - and in a random
order obviously. As a result we can get intertwined mappings, of the type:

+-------+-----------+------+---------+-----------+-------+-------+------+-
| text1 | NOTMAPPED | bss0 | rodata1 | NOTMAPPED | data2 | text3 | bss1 |
+-------+-----------+------+---------+-----------+-------+-------+------+-

  ---------+-
    rodata0 | ...
