ext2_readdir() has always been very fs specific and different
with respect to its ufs_ counterpart. Recent changes from UFS
have made it possible to share more closely the implementation.
MFUFS r252438:
Always start parsing at DIRBLKSIZ aligned offset, skip first entries if
uio_offset is not DIRBLKSIZ aligned. Return EINVAL if buffer is too
small for single entry.
Preallocate buffer for cookies.
Skip entries with zero inode number.

Replace the RESET blocks with regular functions and a reset() function that
calls them all.
This code generation tool is unusual and does not appear to provide much
benefit. I do not think isolating the knowledge about which modules need to
be reset is worth an almost 500-line build tool and wider scope for
variables used by the reset functions.
Also, relying on reset functions is often wrong: the cleanup should be done
in exception handlers so that no stale state remains after 'command eval'
and the like.
These cleanup operations are not needed because they are already performed
after an optimized command substitution (whether there was an error or not).
SVN r95378 refactored ahc_9005_subdevinfo_valid out into a separate

This function is called 4 times in this file, with swapped parameter
ordering. Fix the function definition instead of all the call sites.
16bit/stereo or 8bit/mono playback is unaffected and was probably
working fine before, this should fix 16bit/mono and 8bit/stereo
playback.

locks don't accidentally appear to have been already
initialized.
In particular, this fixes a consistent kernel crash on
armv6 with:
panic: lock "vm map (user)" 0xc09cc050 already initialized
that appeared with r251709.
PR: arm/180820
Kernel include files (i.e. sys/*.h) come first; normally, include
<sys/types.h> OR <sys/param.h>, but not both. <sys/types.h> includes
<sys/cdefs.h>, and it is okay to depend on that.
to those that are universally administered. While it is possible to
add locally administered MAC addresses, it's unclear whether those
are (expected) to be more unique than random multicast MAC addresses
or not.
With many U-Boot configurations assigning fixed and non-official MAC
addresses to ethernet ports and without setting the 'X' flag, this
change may have very little value in the embedded (development)
space. Uniqueness of the universally administered addresses is non-
existent on the (H/W) bench and questionable under the (S/W) desk.
In short: this change is aimed at production environments...
it gets built 16 times in parallel in the same location.
While we are at it, until we finish getting rid of fmake,
be explicit about the make we want to use, thus avoid the problem
of the temp make being the wrong version.

- move init and fini code into separate functions (like it is done upstream)
- invoke fini code via shutdown_post_sync event hook
This should make zfs close its underlying devices during shutdown,
which may be important for their drivers.

Also directly call swapper() at the end of mi_startup instead of
relying on swapper being the last thing in sysinits order.
Rationale:
- "RUN_SCHEDULER" was misleading, scheduling already takes place at that stage
- "scheduler" was misleading, the function swaps in the swapped out processes
- another SYSINIT(SI_SUB_RUN_SCHEDULER, SI_ORDER_ANY) could never be
invoked depending on its relative order with scheduler; this was not obvious
and the bug actually used to exist

All other places where a znode is allocated do not need z_vnode at all.
These are:
- zfs_create_share_dir
- zfs_create_fs
This chnage ensures two things:
- VN_LOCK_ASHARE is not erroneously called for VFIFO vnodes
- vn_lock is called on a fully constructed vnode with correct v_ops
The change also allows to make zfs_znode_cache_constructor a normal
kmem_cache constructor again (as it is in upstream).
This allows to avoid a problem where zfs_znode_cache_destructor
may be called on un-constructed znodes.

addresses added to the UUID generator using uuid_ether_add(). The
UUID generator keeps an arbitrary number of MAC addresses, under
the assumption that they are rarely removed (= uuid_ether_del()).
This achieves the following:
1. It brings up closer to having the network stack as a loadable
module.
2. It allows the UUID generator to filter MAC addresses for best
results (= highest chance of uniqeness).
3. MAC addresses can come from anywhere, irrespactive of whether
it's used for an interface or not.
A side-effect of the change is that when no MAC addresses have been
added, a random multicast MAC address is created once and re-used if
needed. Previusly, when a random MAC address was needed, it was
created for every call. Thus, a change in behaviour is introduced
for when no MAC addresses exist.
