45ab79431b Add a section describing how to tune ARM kernel options to use an MD_ROOT
filesystem larger than about 50-55 MiB.

The description of VM_KMEM_SIZE_SCALE is roughly as hand-wavy as my
understanding of the option, but at least mentioning that it's a factor
and giving an empirical datapoint that works will give folks some idea
of what to tweak if they have problems.

ebff39fb9b [mips] fix compilation of TP-WN1043ND kernel configuration
This compilation issue has been found thanks to freebsd-wifi-build:
 - gpioiic requires "gpio_if.h", so "device gpio" is mandatory
 - rtl8366rb works over MDIO interface, so "device mdio" is mandatory

Compilation is checked on FreeBSD 12-CURRENT machine.

513581749b Add a new ARM kernel option, LOCORE_MAP_MB, to control the size of the
kernel VA mapping in the temporary page tables set up by locore-v6.S.

The number used to be hard-coded to 64MB, which is still the default if
the kernel option is not specified.  However, 64MB is insufficient for
using a large mdroot filesystem.  The hard-coded number can't be safely
increased because too large a number may run into memory-mapped IO space
on some SoCs that must not be mapped as ordinary memory.

fec296887f Refactor vm_map_find(), creating a separate function, vm_map_alignspace(),
for finding aligned free space in the given map.  With this change, we
always return KERN_NO_SPACE when we fail to find free space.  Whereas,
previously, we might return KERN_INVALID_ADDRESS.  Also, with this change,
we explicitly check for address wrap, rather than relying upon the map's
min and max addresses to establish sentinel-like regions.

This refactoring was inspired by the problem that we addressed in r326098.

198ca831a1 extres/syscon: Commit missing bits from r327106
r327106 introduced kobj to syscon so it can be subclassed and fit in with
the rest of the syscon framework. The diff for syscon.c was misapplied in a
clean tree prior to commit, so bring it back to what was included in the
review and tested. The entire file has basically been rewritten from what
was present prior to the kobj work.

cd90150413 When adding support for sending SCTP packets containing an ABORT chunk
to ipfw in https://svnweb.freebsd.org/changeset/base/326233,
a dependency on the SCTP stack was added to ipfw by accident.

This was noted by Kevel Bowling in https://reviews.freebsd.org/D13594
where also a solution was suggested. This patch is based on Kevin's
suggestion, but implements the required SCTP checksum computation
without any dependency on other SCTP sources.

While there, do some cleanups and improve comments.

Thanks to Kevin Kevin Browling for reporting the issue and suggesting
a fix.

d9aed21ce3 Match unattached devices on the system to potential kernel modules.
devmatch(8) matchs up devices in the system device tree with drivers
that may match them. For each unattached device in the system, it
tries to find matching PNP info in the linker hints and prints modules
to load to claim the devices.

In --unbound mode, devmatch can look for drivers that have attached to
devices in the device tree and have plug and play information, but for
which no PNP info exists. This helps find drivers that haven't been
converted yet that are in use on this system.

In addition, the ability to dump out linker.hints is provided.

Future commits will add hooks to devd.conf and rc.d to fully automate
using this information.

280d15cd0a Fix two problems with the page daemon control loop.
Both issues caused the page daemon to erroneously go to sleep when
applications are consuming free pages at a high rate, leaving the
application threads blocked in VM_WAIT.

1) After completing an inactive queue scan, concurrent allocations may
   have prevented the page daemon from meeting the v_free_min threshold.
   In this case, the page daemon was going to sleep even when the
   inactive queue contained plenty of clean pages.
2) pagedaemon_wakeup() may be called without the free queues lock held.
   This can lead to a lost wakeup if a call occurs after the page daemon
   clears vm_pageout_wanted but before going to sleep.

Fix 1) by ensuring that we start a new inactive queue scan immediately
if v_free_count < v_free_min after a prior scan.

Fix 2) by adding a new subroutine, pagedaemon_wait(), called from
vm_wait() and vm_waitpfault(). It wakes up the page daemon if either
vm_pages_needed or vm_pageout_wanted is false, and atomically sleeps
on v_free_count.

34f4d02c2f Fix clang 6.0.0 compiler warnings in binutils
Latest clang git has a warning -Wnull-pointer-arithmetic which will
trigger a -Werror failure. Addition and subtraction from a null pointer
is undefined behaviour and could be optimized into anything.

Furthermore, using the difference between two pointers and casting the
result back to a pointer is not portable since the size of ptrdiff_t
does not necessary have to be the same as size of void* (this happens
e.g. on CHERI). Using intptr_t instead fixes this portability issue and
the compiler warning.

to know what they are doing.
