Rtld did not set FD_CLOEXEC on its internal file descriptors; therefore,
such a file descriptor may be passed to a process created by another thread
running in parallel to dlopen() or fdlopen().
No other threads are expected to be running during parsing of the hints
and libmap files but the file descriptors need not be passed to child
processes so add O_CLOEXEC there as well.
This change will break fdlopen() (as used by OpenPAM) on kernels without
F_DUPFD_CLOEXEC (added in July). Note that running new userland on old
kernels is not supported.

Otherwise we could fail with an incorrect error if e.g. parent
object id is removed too or we can even return a wrong vnode if
parent object has been already re-used.

flags. If a caller doesn't mind a doomed vnode, then zfs should deliver.

It turned out to be not that useful, because its default value may lead
to a problem when a root pool is present in zpool.cache, but its
on-disk status is 'exported'. This may happen if the pool was imported
in a different environment with -f flag and then exported.

The copies of initarm used on platforms with FDT support were almost
identical. The differences were pulled out into separate functions that
were called by initarm.
This change merges the, now identical, copies of initarm and a few of it's
support functions. This is a step towards a common kernel on ARMv6.
Although sufficient memory is available for a longer string in cmdname,
this is undefined behaviour anyway.
Side effect: for alignment reasons, an additional byte of memory is
allocated per hashed command.

that the APs get configured the same as the BSP, irrspective
of how FreeBSD was loaded.
2. Make sure to flush the dcache after writing the TLB1 entries
to the boot page. The APs aren't part of the coherency domain
just yet.
3. Set pmap_bootstrapped after calling pmap_bootstrap(). The
FDT code now maps the devices (like OF), and this resulted
in a panic.
4. Since we pre-wire the CCSR, make sure not to map chunks of
it in pmap_mapdev().
The automation can set TARGET_ARCH and TARGET and then make various
top-level targets, including buildLINT and buildkernel (with
KERNCONF=LINT). Previously there was no way to generate the LINT
kernel configuration without having to do something exceptionally
painful.
