Most of the gpio controller cannot configure or get the configuration
of the pin muxing as it's usually handled in the pinctrl driver.
But they can know what is the pinmuxing driver either because they are
child of it or via the gpio-range property.
Add some new methods to fdt_pinctrl that a pin controller can implement.
Some methods are :
fdt_pinctrl_is_gpio: Use to know if the pin in the gpio mode
fdt_pinctrl_set_flags: Set the flags of the pin (pullup/pulldown etc ...)
fdt_pinctrl_get_flags: Get the flags of the pin (pullup/pulldown etc ...)
The defaults method returns EOPNOTSUPP.

arichardson has an actual fix for the same issue that this was working
around; given that we don't build with llvm today, go ahead and revert the
workaround in advance.
This provides a specific pointer for users of tap(4) to understand why their
interfaces are losing their addresses, and specifically how to workaround
this if they need different behavior.
This manpage received a .Dd bump earlier today in r35688, so no bump occurs
this time.

Explicitly setting WITHOUT_KERBEROS implies WITHOUT_KERBEROS_SUPPORT,
but previously other cases that forced KERBEROS off (such as
WITHOUT_CRYPT) did not also set KERBEROS_SUPPORT off. Because the
_SUPPORT dependent options (KERBEROS/KERBEROS_SUPPORT) are processed
before other dependencies (CRYPT/KERBEROS) it's not easy to make this
happen automatically. Instead just explicitly set KERBEROS_SUPPORT
off where we set KERBEROS off.

hard use floating point hardware, pass registers to functions in
floating point registers.
softfp use floating point hardware, but pass registers to functions
in integer registers.
soft do floating point calcuations without using floating point
hardware. Pass arguments in integer registers.
FreeBSD 11 and newer assumes hard. 10 and earlier assumed softfp. We have no
real support, at the moment, for soft. It's untested, though, if softfp still
works.
Add a note here since this is a whack-a-doodle combination relative to all other
platforms.
softfp is likely to go away in the future because it was retained for people
using FreeBSD 10 + armv6 needing to transition more slowly from softfp -> hard
than the project. It likely is no longer needed, and may be getting in the
way of people needing 'soft' support.
It's not immediately clear by what mechanism loader(8) will be loading the
preloaded file. Specifically name-drop loader.conf(5) with a pointer to the
module loading section and a description of what the 'name' should look
like, because that certainly isn't clear from the loader.conf(5) standpoint.
The default loader.conf already has a pointer to md(4) where it appears and
the reference to loader.conf in the new version of this manpage should make
it more clear that this is where one should look for information.

- Move flag VTOSLAB from public to private.
- Introduce public NOTPAGE flag and make HASH private.
- Introduce public NOTOUCH flag and make OFFPAGE private.
- Update man page.
The net effect of this should be to make the contract with clients more
clear. Clients should choose constraints, UMA will figure out how to
implement them. This also breaks the confusing double meaning of
OFFPAGE.

Only sparc64 did not enable LLVM_LIBUNWIND. After r356513 LLVM_LIBUNWIND
should at least build on sparc64. The old DWARF unwinder will be removed
along with GCC 4.2.1 in the near future, so switch sparc64 to use LLVM's
unwinder in advance of the removal. Someone with access to the obsolete
sparc64 hardware supported by FreeBSD will have to test, and investigate
any failures. I will gladly help, but I don't have any suitable hardware
myself.

This allows cheapest DRAM-less NVMe SSDs to use some of host RAM (about
1MB per 1GB on the devices I have) for its metadata cache, significantly
improving random I/O performance. Device reports minimal and preferable
size of the buffer. The code limits it to 1% of physical RAM by default.
If the buffer can not be allocated or below minimal size, the device will
just have to work without it.

This re-enables building the googletest suite by default on mips and instead
specifically doesn't build fusefs tests for mips+clang builds. clang will
easily spent >= 1.5 hours compiling a single file due to a bug in
optimization (see LLVM PR 43263), so turn these off for now while that's
hashed out.
GCC builds are unaffected and build the fusefs tests as-is. Clang builds
only happen by early adopters attempting to hash out the remaining issues.
The comment has been updated to reflect its new position and use less strong
wording about imposing on people.

Extend r356379 to include 32-bit mips and sparc64. Using a decade-old
binutils linker with a contemporary compiler (either Clang or GCC) is
a combination unlikely to be used by anyone else, and it's not going
to be a good use of our time investigating and addressing any issues
that arise. Expect that all architectures newly migrated to external
GCC will also use external binutils.
After GCC was disabled by default in r356367, mips and sparc64 started
relying external GCC. However, the in-tree Binutils ld 2.17.50 is not
compatible with GCC for some mips64 targets, so turn off
BINUTILS_BOOTSTRAP and rely on external binutils (linker) as well.
For libssp.so, rebuild stack_protector.c with FORTIFY_SOURCE stubs that just
abort built into it.
For libssp_nonshared.a, steal stack_protector_compat.c from
^/lib/libc/secure and massage it to maintain that __stack_chk_fail_local
is a hidden symbol.
libssp is now built unconditionally regardless of {WITH,WITHOUT}_SSP in the
build environment, and the gcclibs version has been disconnected from the
build in favor of this one.
