3453bca864 Eliminate every mention of PG_CACHED pages from the comments in the machine-
independent layer of the virtual memory system.  Update some of the nearby
comments to eliminate redundancy and improve clarity.

In vm/vm_reserv.c, do not use hyphens after adverbs ending in -ly per
The Chicago Manual of Style.

Update the comment in vm/vm_page.h defining the four types of page queues to
reflect the elimination of PG_CACHED pages and the introduction of the
laundry queue.

5afb134c32 vfs: add vrefact, to be used when the vnode has to be already active
This allows blind increment of relevant counters which under contention

3ce73b2662 Fix gic_cpu_mask() calculation in ARM GIC
r309616 changed the definition of GICD_ITARGETSR(n) to take the irq
id as argument, but the usage of the macro in gic_cpu_mask() was not
updated to reflect this. This causes the cpu mask to be computed
incorrectly.

Update the GICD_ITARGETSR() call to fix this, this fixes a hang seen
while booting freebsd on qemu-system-aarch64 with SMP enabled.

7d9082cafa Increase interrupt cells in generic_pcie_fdt_route_interrupt
ARM GIC specification in device trees use 3 cells, so the current
limit of 2 causes the last cell to be dropped. This in turn can
cause the interrupt polarity and trigger settings to be incorrect.

Increase the limit to 4 which should handle all reasonable cases.
This fixes issues seen in QEMU when registering PCI interrupts.

545d312293 When a zombie gets reparented due to the parent exit, send SIGCHLD to
the reaper.

The traditional reaper init(8) is aware of zombies silently reparented
to it after the parents exit, it loops around waitpid(2) to collect
them.  For other reapers, the silent reparenting is surprising and
collecting zombies requires a thread blocking in waitpid(2) just for
that purpose.  It seems that sending second SIGCHLD is a better
workaround than forcing all reapers to obey the setup.

5a1842a24a Add ip6_tryforward() - a run to completion forwarding implementation
for IPv6.

It gets performance benefits from reduced number of checks. It doesn't
copy mbuf to be able send ICMPv6 error message, because it keeps mbuf
unchanged until the moment, when the route decision has been made.
It doesn't do IPsec checks, and when some IPsec security policies present,
ip6_input() uses normal slow path.

b6ff672460 We currently don't do TSO if ip options are present. In case of IPv6, we look at
in6p_options to check that. That is incorrect as we carry ip options in
in6p_outputopts. Also, just checking for in6p_outputopts being NULL won't
suffice as we combine ip options and ip header fields both in that one field.
The commit fixes this by using ip6_optlen() which correctly calculates length
of only ip options for IPv6.

2823b6467a Postpone ZVOL media/block size caching till first open.
At least on FreeBSD there are no legal way to access media or get its
size without opening device/provider first.  Postponing this caching
allows to skip several disk seeks per ZVOL/snapshot during import.

For HDD pool with 1 ZVOL in dev mode with 1000 snapshots this reduces
pool import time from 40 to 10 seconds.

cc7734cbac Change the process limits for RLIMIT_MEMLOCK to RLIM_INFINITY when
executing :mincore_resid

The default process limits in FreeBSD is 64kB for unprivileged users,
which empirically is too low to run the :mincore_resid testcase.

Process limits are inherited, so even though the default limit for
root users is RLIM_INFINITY, the inherited limit with "sudo" with the
default login.conf will be 64kB.

Use setrlimit to set rlim_max for RLIMIT_MEMLOCK to RLIM_INFINITY to
avoid ENOMEM issues when calling mlock to wire the mmap'ed address
space.

setrlimit requires root access to increase rlim_max, so require root
privileges when running the test

Discovered when executing the tests with sudo, e.g.
"sudo kyua test -k /usr/tests/lib/libc/sys/Kyuafile mincore_test"
