35b5051ab9 complete_rqe: explicitly reinitialize b.b_iodone. This shouldn't have
changed, but we've seen some weird cases of b_iodone
	      being NULL, and they don't make any sense.

ca55837990 config_plex: don't allocate a rangelock struct.
lockrange: correctly expand rangelock struct, including expanding a
	   null struct.  Previously lockrange would attempt to lock a
	   NULL pointer under these circumstances.

399f34180a Use .p2align to ensure consistant a.out/elf alignment. I'd have used
SUPERALIGN_TEXT, but this is inline assembler and after cpp has run.

4a54450a9d It would help if things that MUST be 32 bit aligned were really 32 bit
aligned.  If I recall correctly, this is to ensure apic_imen can be
accessed in a single bus cycle.  Also, use TEXT_ALIGN rather than a
.align 2 (which means 2 byte align on ELF and 4 byte align on a.out)

c85f67175f Fix {g|s}etgroups semantics. We use cr_groups[0] to hold egid. This means that
egid will be twice in the set and that setting cr_groups[0] will change egid.
This is simply solved by ignoring cr_groups[0]. That is; linux_getgroups does
not return cr_groups[0] and linux_setgroups does not touch it.

0ff7b13acd Make DEVFS use PHK's specinfo struct as the source of dev_t and devsw.
In lookup() however it's the other way around as we need to supply the
dev_t for the vnode, so devfs still has a copy of it stashed away.

Sourcing it from the vnode in the vnops however is useful as it makes
a lot of the code almost the same as that in specfs.

2053751093 Make DEVFS ops reflect some of the changes that have recently occured in the
specfs version of the same ops. Merging with phk's dev_t changes is not yet
complete.

i.e. devfs still uses it's own devsw pointer rather than following
devsw(a_vp->v_rdev), and it's own copy of the dev_t.

This fixes some broken actions re: syscons and DEVFS due to bitrot in
devfs vops.

076dab2983 When the SYSINIT() was removed, it was replaced with a make_dev on-demand
creation of /dev/drum via calling swapon. However, the make_dev has a
bogus (insofar that it hasn't been added yet) cdevsw, so later we end
up crashing with a null pointer dereference on the swap vp's specinfo.
The specinfo points to a dev_t with a major of 254 (uninitialized), and
we get a crash on its d_strategy being called.

The simple solution to this is to call cdevsw_add before the make_dev
is ever used. This fixes the panic which occurred upon swapping.

0f41c63996 Change PN_RXLEN from 1518 bytes to 1536 bytes. The chip always DMAs data
in 4 byte chunks. It turns out that with the 82c169C on the Netgear
FA-310TX Rev D2, if you tell the chip you have reserved a buffer of 1518
bytes, it will actually treat it as 1516 bytes since 1518 is divisible
by four. Consequently, a packet of 1514 bytes will always end up consuming
two buffers: the last coupleof bytes will spill over into the next
descriptor. This causes the pn_rx_bug_war() routine to trip unnecessarily.

I'm not sure if the 82c169B or 82c168 chips behave the same way; I'll
have to check them. In any case, this change should work just as well
with them. Note that the FA-310TX Rev D2 also has a Broadcom PHY
instead of a Level One LXT970 PHY, however this shouldn't make any
difference as far as the driver is concerned.

This change also allows me to do a way with one rounding overation in
pn_rx-buf_war().
