We do not treat makefs as contrib code. Import copies of makefs msdos
files from NetBSD so that we can track our changes to these files.
These are copied from NetBSD, with only a change to use __FBSDID and
$FreeBSD$ instead of __KERNEL_RCSID and $NetBSD$. A copy of the
original $NetBSD$ tag remains in each source file.
These two files were missed in r320212. Also remove a stray blank line
added in msdosfs_vfsops.c.

dim@ compared clang IAS-built and GNU as-built boot0 and found them
equivalent. IAS encoded one instruction using two bytes where GNU as
used three, and another instruction using three bytes where GNU as used
two. The net result is equivalent and tested, so there is no need to
force IAS off for boot0.
The -B was originally added in projects/release-pkg r289381 as a copy
of what 'make world' did at the time. The -B was removed from
the 'installworld' call in 'world' in r303844 though. The staging
of files is safe to run in parallel.

Add forward compatibility so that new binaries can run on old
kernels. If the new system call from ino64 isn't available on your
system, then the old one will be used and the results translated. The
stat and statfs families of functions are fully emulated. While not
required by policy, in this case it is helpful to our users to provide
this compatibility. In this case, it allows rollback of the kernel
after installing a new userland should a problem be discovered. It
also prevents foot-shooting if a user does an install before rebooting
with the new kernel. Finally, it allows the use case where one needs
to run new binaries on an old kernel as part of an upgrade process.
The getdirentries family uses tricks that may not work on remote
filesystems. Specifically, it uses a buffer 1/4 the size requested to
get the data from he old syscall.
The code carefully uses direct syscalls for old system calls to avoid
referencing freebsd11_* symbols, which contaminate ld-elf.so.1's
export table due to its use of stat functions, which causes errno to
be incorrect in client programs due to the wrong *stat* function being
resolved in some cases.
This code should removed sometime after 12 is branched.
Tested on: 12-current binaries on a 10.3-beta kernel run and return
consistent results. 12-current kernel and userland with
packages from before ino64 was committed also work.

A Build-ID is an identifier generated at link time to uniquely identify
ELF binaries. It allows efficient confirmation that an executable or
shared library and a corresponding standalone debuginfo file match.
(Otherwise, a checksum of the debuginfo file must be calculated when
opening it in a debugger.)
The FreeBSD base system includes GNU bfd ld 2.17.50 as the linker for
architectures other than arm64. Build-ID support was added to bfd ld
shortly after that version, so was not previously available to us.
We can now start making use of Build-ID as we migrate to using lld or
bfd ld from ports, conditionally enabled based on the LINKER_TYPE and
LINKER_VERSION make variables added in r320244 and subsequent commits.

Thanks to Anselm Jonas Scholl for reporting it and providing a patch.
GNU binutils includes two linkers: ld.bfd and ld.gold. For clarity use
LINKER_TYPE=bfd to refer to ld.bfd, the original binutils linker that
identifies itself as "GNU ld".

- Rename chroot_arm_armv6_build_release() to chroot_arm_build_release()
and make it hardware agnostic (such as armv6 -vs- armv7 -vs- arm64).
- Evaluate EMBEDDED_TARGET differently so release/tools/arm.subr can
be used for arm/armv6 and arm64/aarch64.
- Update comments and copyright.
In release/tools/arm.subr:
- In arm_create_disk(), change the default alignment from 63 to 512k,
fixing a boot issue on arm64 and EFI. [1]

INFORMATION ON UTC - TAI
NO leap second will be introduced at the end of June 2017.
The difference between Coordinated Universal Time UTC and the
International Atomic Time TAI is :
from 2017 January 1, 0h UTC, until further notice : UTC-TAI = -37 s
Leap seconds can be introduced in UTC at the end of the months of December
or June, depending on the evolution of UT1-TAI. Bulletin C is mailed every
six months, either to announce a time step in UTC, or to confirm that there
will be no time step at the next possible date.

FreeBSD's C library uses __STDC_VERSION__ to determine whether the
compiler provides language features specific to a certain version of the
C standard. __ISO_C_VISIBLE is used to specify which library features
need to be exposed.
max_align_t currently uses __STDC_VERSION__, even though it should be
using __ISO_C_VISIBLE to remain consistent with the rest of the headers
in include/.

There are disk devices that have logical sector size larger than 512B, for
example 4KB. That is, their physical sector size is larger than 512B and they
do not provide emulation for 512B sector sizes. For such devices both a data
offset and a data size must be properly aligned. L2ARC should arrange that
because it uses physical I/O.
zio_vdev_io_start() performs a necessary transformation if io_size is not
aligned to vdev_ashift, but that is done only for logical I/O. Something
similar should be done in L2ARC code.
* a temporary write buffer should be allocated if the original buffer is
not going to be compressed and its size is not aligned
* size of a temporary compression buffer should be ashift aligned
* for the reads, if a size of a target buffer is not sufficiently large and
it is not aligned then a temporary read buffer should be allocated
