These filters "hit" before anything else in the LE's lookup. The exact

a) High priority filters

c) Servers (TOE hw listeners)
d) Normal filters

On PowerPC (and possibly other architectures), that doesn't use
EARLY_AP_STARTUP, the config task queue may be used initialized.
This was observed while trying to mount the root fs from NFS, as
reported here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230168.
This patch has 2 main changes:
1- Perform a basic initialization of qgroup_config, similar to
what is done in taskqgroup_adjust, but simpler.
This makes qgroup_config ready to be used during NFS root mount.
2- When EARLY_AP_STARTUP is not used, call inm_init() and
in6m_init() right before SI_SUB_ROOT_CONF, because bootp needs
to send multicast packages to request an IP.

We use ps to collect the information of all processes in textdump. But
it doesn't contain process arguments which however sometimes are very
useful for debugging. The new 'a' modifier adds that capability.
While here, remove 'm' modifier from ddb.4. It was in the manual page
from its very first revision, but I could not find any evidence of the
code ever supporting it.

From the "newly licensed to drive" PR department, add a BOOT_TAG marker (by
default, --<<BOOT>>--, to the beginning of each boot's dmesg. This makes it
easier to do textproc magic to locate the start of each boot and, of
particular interest to some, the dmesg of the current boot.
The PR has a dmesg(8) component as well that I've opted not to include for
the moment- it was the more contentious part of this PR.
bde@ also made the statement that this boot tag should be written with an
ordinary printf, which I've- for the moment- declined to change about this
patch to keep it more transparent to observer of the boot process.

Using a space as the magic character would result in problems if the command
started with a number:
- For a 'valid' number n, n < size of argv, it would erroneously get
replaced with that argument; e.g. `apply -a ' ' -d 1rm x => `execxrm x`
- For an 'invalid' number n, n >= size of argv, it would segfault.
e.g. `apply -a ' ' 2to3 test.py` would try to access argv[2]
This problem occurred because apply(1) would prepend "exec " to the command
string before doing the actual magic number replacements, so it would come
across "exec 2to3 1" and assume that the " 2" is also a magic number to be
replaced.
Re-work this to instead just append "exec " to the command sbuf and
workaround the ugliness. This also simplifies stuff in the process.

If OPAL_RTC_READ is busy and does not return the information on the first run,
as returning OPAL_BUSY_EVENT, the system will crash since ymd and hmsm variable
will contain junk values.
This is happening because we were not calling OPAL_RTC_READ again after
OPAL_POLL_EVENTS' return, which would finally replace the old/junk hmsm and ymd
values.
The code was also mixing OPAL_RTC_READ and OPAL_POLL_EVENTS return values.
This patch fix this logic and guarantee that we call OPAL_RTC_READ after
OPAL_POLL_EVENTS return, and guarantee the code will only proceed if
OPAL_RTC_READ returns OPAL_SUCCESS.

argv has been incremented during argument handling, so elements of the
array are no longer valid. Change the err() arguments so only the
first string pointer in argv is used.
Found during code inspection.
After a re-read of the appropriate section of RFC5661, I decided that a
few things should be changed related to LayoutRecall callback handling.
Here are the things fixed by this patch.
- For two of the three cases that LayoutRecall is done, I now think
setting the clora_changed argument false is correct.
- All errors other than NFSERR_DELAY returned by LayoutRecall appear
permanent, so don't retry for any of them. (NFSERR_DELAY is retried by
newnfs_request(), so it is not affected by this patch.)
- Instead of waiting "forever" (actually until the process is SIGTERM'd)
for Layouts to be returned during a mirror copy, fail and return
ENXIO after about 1minute.
Waiting for a <ctrl>C made sense when pnfsdscopymr() was done by itself,
but did not make sense when done via find(1).
This patch only affects the pNFS server.

add support for explicitly requesting that pmap_enter() create a 1 MB page
mapping. (Essentially, this feature allows the machine-independent layer
to create superpage mappings preemptively, and not wait for automatic
promotion to occur.)
Export pmap_ps_enabled() to the machine-independent layer.
Add a flag to pmap_pv_insert_pte1() that specifies whether it should fail
or reclaim a PV entry when one is not available.
Refactor pmap_enter_pte1() into two functions, one by the same name, that
is a general-purpose function for creating pte1 mappings, and another,
pmap_enter_1mpage(), that is used to prefault 1 MB read- and/or execute-
only mappings for execve(2), mmap(2), and shmat(2).
In addition, as an optimization to pmap_enter(..., psind=0), eliminate the
use of pte2_is_managed() from pmap_enter(). Unlike the x86 pmap
implementations, armv6 does not have a managed bit defined within the PTE.
So, pte2_is_managed() is actually a call to PHYS_TO_VM_PAGE(), which is O(n)
in the number of vm_phys_segs[]. All but one call to PHYS_TO_VM_PAGE() in
pmap_enter() can be avoided.
