adee32cbcc pf: address family must be set when creating a pf_fragment
Fix a panic when handling fragmented ip4 packets with 'drop-ovl' set.
In that scenario we take a different branch in pf_normalize_ip(), taking us to
pf_fragcache() (rather than pf_reassemble()). In pf_fragcache() we create a
pf_fragment, but do not set the address family. This leads to a panic when we
try to insert that into pf_frag_tree because pf_addr_cmp(), which is used to
compare the pf_fragments doesn't know what to do if the address family is not
set.

Simply ensure that the address family is set correctly (always AF_INET in this
path).

d7bc9285a6 Implement lockless resource limits.
Use the same scheme implemented to manage credentials.

Code needing to look at process's credentials (as opposed to thred's) is
provided with *_proc variants of relevant functions.

Places which possibly had to take the proc lock anyway still use the proc
pointer to access limits.

67f2eebb44 Generalised support for copy-on-write structures shared by threads.
Thread credentials are maintained as follows: each thread has a pointer to
creds and a reference on them. The pointer is compared with proc's creds on
userspace<->kernel boundary and updated if needed.

This patch introduces a counter which can be compared instead, so that more
structures can use this scheme without adding more comparisons on the boundary.

73775f21e2 Correct a type error in kmem_unback(). Previously, kmem_unback() did not
correctly handle deallocation requests of two or more gigabytes in size.
Eventually, this would lead to a panic elsewhere in the kernel, such as
"vm_radix_insert: key <vm_pindex_t> is already present".

f92ed46073 Add options to dmb() and dsb() macros on ARM64
Using plain dsb()/dmb() as full system barriers is usually to much.
Adding proper options to those barriers (instead of full system - sy)
will most likely reduce the cost of the instructions and will benefit
in performance improvement.
This commit adds options to barrier macro definitions.

aec8808588 Add support for reading MAM attributes to camcontrol(8) and libcam(3).
MAM is Medium Auxiliary Memory and is most commonly found as flash
chips on tapes.

This includes support for reading attributes and decoding most
known attributes, but does not yet include support for writing
attributes or reporting attributes in XML format.

libsbuf/Makefile:
	Add subr_prf.c for the new sbuf_hexdump() function.  This
	function is essentially the same function.

libsbuf/Symbol.map:
	Add a new shared library minor version, and include the
	sbuf_hexdump() function.

libsbuf/Version.def:
	Add version 1.4 of the libsbuf library.

libutil/hexdump.3:
	Document sbuf_hexdump() alongside hexdump(3), since it is
	essentially the same function.

camcontrol/Makefile:
	Add attrib.c.

camcontrol/attrib.c:
	Implementation of READ ATTRIBUTE support for camcontrol(8).

camcontrol/camcontrol.8:
	Document the new 'camcontrol attrib' subcommand.

camcontrol/camcontrol.c:
	Add the new 'camcontrol attrib' subcommand.

camcontrol/camcontrol.h:
	Add a function prototype for scsiattrib().

share/man/man9/sbuf.9:
	Document the existence of sbuf_hexdump() and point users to
	the hexdump(3) man page for more details.

sys/cam/scsi/scsi_all.c:
	Add a table of known attributes, text descriptions and
	handler functions.

	Add a new scsi_attrib_sbuf() function along with a number
	of other related functions that help decode attributes.

	scsi_attrib_ascii_sbuf() decodes ASCII format attributes.

	scsi_attrib_int_sbuf() decodes binary format attributes, and
	will pass them off to scsi_attrib_hexdump_sbuf() if they're
	bigger than 8 bytes.

	scsi_attrib_vendser_sbuf() decodes the vendor and drive
	serial number attribute.

	scsi_attrib_volcoh_sbuf() decodes the Volume Coherency
	Information attribute that LTFS writes out.

sys/cam/scsi/scsi_all.h:
	Add a number of attribute-related structure definitions and
	other defines.

	Add function prototypes for all of the functions added in
	scsi_all.c.

sys/kern/subr_prf.c:
	Add a new function, sbuf_hexdump().  This is the same as
	the existing hexdump(9) function, except that it puts the
	result in an sbuf.

	This also changes subr_prf.c so that it can be compiled in
	userland for includsion in libsbuf.

	We should work to change this so that the kernel hexdump
	implementation is a wrapper around sbuf_hexdump() with a
	statically allocated sbuf with a drain.  That will require
	a drain function that goes to the kernel printf() buffer
	that can take a non-NUL terminated string as input.
	That is because an sbuf isn't NUL-terminated until it is
	finished, and we don't want to finish it while we're still
	using it.

	We should also work to consolidate the userland hexdump and
	kernel hexdump implemenatations, which are currently
	separate.  This would also mean making applications that
	currently link in libutil link in libsbuf.

sys/sys/sbuf.h:
	Add the prototype for sbuf_hexdump(), and add another copy
	of the hexdump flag values if they aren't already defined.

	Ideally the flags should be defined in one place but the
	implemenation makes it difficult to do properly.  (See
	above.)

0500876d98 Extend TPS65217 support to be able to pull and decode battery
charger configuration and provide some basic control knobs to
set charger voltage and dump config on boot. Two loader tunables
have been added:

 o hw.am335x_pmic.bootverbose set to 1 to get more info on the
   boot;

 o hw.am335x_pmic.vo: set to charger voltage to be applied on
   kernel initialization time, supported values are "4.10V",
   "4.15V", "4.20V" and "4.25V".

Cleanup code a bit in general, move TPS65217 register
definitions into a separate header, convert bit-banging
defines into bitmap structures.

Also threat the case when power source is neither "AC" nor "USB"
as "Battery", not "Unknown".

fbb65db559 Switch from make_dev_alias to make_dev_alias_p since make_dev_alias_p can
gracefully fail if the /dev/megaraid_sas_ioctl_node symlink already exists.
This can happen if mfi(4) and mrsas(4) are both attached to cards and
providing Linux emulation support.  Let the first one win.  An equivalent
change needs to be done to mrsas(4).  Extra credit would be to pass the
Linux emulation call to the other driver when appropriate.  This will
probably be a rare case and the user can manually change where the symlink
points to.

557733c8f3 When updating/accessing the timehands, barriers are needed to ensure
that:
- th_generation update is visible after the parameters update is
  visible;
- the read of parameters is not reordered before initial read of
  th_generation.

On UP kernels, compiler barriers are enough.  For SMP machines, CPU
barriers must be used too, as was confirmed by submitter by testing on
the Freescale T4240 platform with 24 PowerPC processors.

8d7fa71fca Handle X2APIC entries in the MADT for APICs with an ID < 255. At least one
BIOS has been seen to include such entries even though the relevant specs
require that X2APIC entries only be used for CPUs with an APIC ID >= 255.

This was tested on a system with "plain" local APIC entries in the MADT
to ensure no regressions, but it has not yet been tested on a system with
X2APIC entries in the MADT.  Currently such systems do not boot at all,
and with this change they might now boot correctly.
