91458022a7 Create a /boot/dtb directory to house DTB blobs. The flattened device
tree support includes a device tree source compiler dtc(8) which
converts .dts files into .dtb files. /boot/loader will load dtb files
from this directory by default, allowing for fewer differences between
images for different SoCs. Compiled dts files will wind up here
eventually as an alternative to embedding them into the kernel.
Document this in hier(7), as well as add missing entries for
/boot/firmware and /boot/zfs, though the latter two should only be
considered place holders if someone wants to make them better.

51325ca40d Always seek back to the beginning of a regular directory, even if the
previous seek location was 0.  Without this, readdir() would see
dd_loc of zero and call getdirentries() which would start reading
entries at the current seek location of the directory ignoring the
first batch of entries.  Also, rewinddir() should always seek so that
it reads the directory from the beginning to get updated entries.

MFV:  Only emit movw on ARMv6T2

Building for the FreeBSD default target ARMv6 was emitting movw ASM on certain
test cases (found building qmake4/5 for ARM).  Don't do that, moreover, the AS
in base doesn't understand this instruction for this target.  One would need
to use --integrated-as to get this to build if desired.

dffba5b7eb Leave the C11 keywords alone when we have a recent version of GCC.
As GCC also gained support for the C11 keywords over time, we can patch
up <sys/cdefs.h> to not define these anymore. This has the advantage
that error messages for static assertions are printed natively and that
_Alignas() will work with even a type outside of C11 mode.

All C11 keywords are supported with GCC 4.7 and higher, with the
exception of _Thread_local and _Generic. These are only supported as of
GCC 4.9.

401c0a1c8f Right now, thread_single(SINGLE_EXIT) returns after the p_numthreads
reaches 1. The p_numthreads counter is decremented in thread_exit() by
a call to thread_unlink(). This means that the exiting threads may
still execute on other CPUs when thread_single(SINGLE_EXIT) returns.
As result, vmspace could be destroyed while paging structures are
still used on other CPUs by exiting threads.

Delay the return from thread_single(SINGLE_EXIT) until all threads are
really destroyed by thread_stash() after the last switch out. The
p_exitthreads counter already provides the required mechanism, move
the wait from the thread_wait() (which is called from wait(2) code)
into thread_single().

dc78f18afe Allow standalone debug for non-default ${PROG} targets
This allows WITH_DEBUG_FILES to produce standalone debug for the ELF
runtime linker.

We previously disabled standalone debug files for bsd.prog.mk consumers
that included a non-default ${PROG} target, but this is not required.

Consumers that do not support standalone debug are still handled by
disabling it for statically linked binaries, and for those that specify
a non-default binary format.

944d759ab7 Create an interface for drivers to enable or disable their clocks as listed
in the clocks=<...> properties of their FDT data.  The clock properties
consist of 2-cell tuples, each containing a clock device node reference and
a clock number.  A clock device driver can register itself as providing
this interface, then other drivers can turn the FDT clock node reference
into the corresponding device_t so that they can use the interface to query
and manipulate their clocks.

This provides convenience functions to enable or disable all the clocks
listed in the properties for a device, so most drivers will be able to
manage their clocks with a single call to fdt_clock_enable_all(dev).
