2077be2b73 cam(4): Add an xpt-neutral flag indicating a valid panic CCB
No functional change.

Note that this change is careful to set the CCB header xflags after
foo_fill_bar() routines, which generally zero existing flags.  An earlier
version of this patch mistakenly set the flag before the fill routines.

89edb881e6 Add optional LLVM BPF target support
BPF (eBPF) is an independent instruction set architecture which is
introduced in Linux a few years ago. Originally, eBPF execute
environment was only inside Linux kernel. However, recent years there
are some user space implementation (https://github.com/iovisor/ubpf,
https://doc.dpdk.org/guides/prog_guide/bpf_lib.html) and kernel space
implementation for FreeBSD is going on
(https://github.com/YutaroHayakawa/generic-ebpf).

The BPF target support can be enabled using WITH_LLVM_TARGET_BPF, as it
is not built by default.

50a2c22918 libnv: Remove -I${SRCTOP}/sys
This should have been done as part of r336019 -- including ${SRCTOP}/sys is
not a good business model for something that's build in legacy/bootstrap
stages.

Beyond that, libnv seems to build quite alright as legacy, part of
buildworld, and standalone without. Axe it.

b50a4ea646 Account for the lowmem handlers in the inactive queue scan target.
Before r329882 the target would be computed after lowmem handlers run
and free pages.  On some systems a significant amount of page
reclamation happens this way.  However, with r329882 the target is
computed first, which can lead to unnecessary reclamation from the
page cache, and this in turn may result in excessive swapping.

Instead, adjust the target after running lowmem handlers.  Don't
invoke the lowmem handlers before the PID controller, though, since
that would hide the true rate of page allocation.

2a4650cc11 BOOT_TAG: Make a config(5) option, expose as sysctl and loader tunable
BOOT_TAG lived shortly in sys/msgbuf.h, but this wasn't necessarily great
for changing it or removing it. Move it into subr_prf.c and add options for
it to opt_printf.h.

One can specify both the BOOT_TAG and BOOT_TAG_SZ (really, size of the
buffer that holds the BOOT_TAG). We expose it as kern.boot_tag and also add
a loader tunable by the same name that we'll fetch upon initialization of
the msgbuf.

This allows for flexibility and also ensures that there's a consistent way
to figure out the boot tag of the running kernel, rather than relying on
headers to be in-sync.

c8e2123b6a [ppc] Fix kernel panic when using BOOTP_NFSROOT
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.

2834d61202 kern: Add a BOOT_TAG marker at the beginning of boot dmesg
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.

f032f7b307 apply(1): Fix magic number substitution with magic character ' '
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.

78f4e2fea0 powerpc64/powernv: re-read RTC after polling
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.

41df1b5b47 Assorted fixes to handling of LayoutRecall callbacks, mostly error handling.
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.
