Four drivers (hpt27xx, hptmv, hptnr, hptrr, hpt27xx) include precompiled
binary objects; have users load them as modules if they are needed.
Additional work (i.e., integrating devmatch) required before MFC.

The feature is implemented as an extension of the existing
ZFS_IOC_RENAME ioctl. Both the userland and the DSL interfaces support
renaming only a single bookmark at a time. As of now, there is no ZCP
interface to the new functionality. I am going to add it once the DSL
interface passes a test of time.
This change picks up support for zfs_ioc_namecheck_t::ENTITY_NAME that
was added to ZoL as part of Redacted Send/Receive feature by Paul
Dagnelie <pcd@delphix.com>. This is needed to allow a bookmark name in
zc_name.

private data.
- Use NG_NODE_FOREACH_HOOK() to traverse through hooks instead of array.

It was defined with the wrong MACHINE_ARCH previously. This permits
using an MFS image without defining MD_ROOT_SIZE which has various
benefits (one being that the build is able to treat the MFS image as
a dependency and properly re-link the kernel with the new image when
building with NO_CLEAN).

MAXPATHLEN / PATH_MAX includes space for the terminating NUL, and namei
verifies the presence of the NUL. Thus there is no need to increase the
buffer size here.
The sysctl passes the string excluding the NUL, so req->newlen equal to
PATH_MAX is too long.

Provide *cmpset_{8,16} as wrappers around atomic_fcmpset_32. Initial users
will be mips and sparc64, and perhaps parts of powerpc.
This are not for general consumption; machine/atomic.h should include this
header as needed to provide atomic_{,f}cmpset_{8,16} and machine/atomic.h

The mountpoint may not have defined an iosize parameter, so an attempt
to configure readahead on a device file can lead to a divide-by-zero
crash.
The sequential heuristic is not applied to I/O to or from device files,
and posix_fadvise(2) returns an error when v_type != VREG, so perform
the same check here.

For ll/sc architectures, atomic(9) allows failure modes where *old == val
due to write failure and callers should compensate for this. Do not retry on
failure, just leave 0 in ret and fail the operation if we couldn't sc it.
This lets the caller determine if it should retry or not.

Before attempting to initialize the command interface we must wait till
the fw_initializing bit is clear.
If we fail to meet this condition the hardware will drop our
configuration, specifically the descriptors page address. This scenario
can happen when the firmware is still executing an FLR flow and did not
finish yet so the driver needs to wait for that to finish.
