init_desc, by always ORing with 1 for the descriptor header inclusion
into the descriptor length, and init_sh_desc_pdb, by always specifying
the descriptor length modification for the PDB via options, would not
allow for odd length PDBs to be embedded in the constructed descriptor
length. Fix this by simply changing the OR to an addition.
also round-up pdb_bytes to the next SEC command unit size, to
allow for, e.g., optional packet header bytes that aren't a

It has been observed that sometimes the crypto allocation code
will get stuck for 60 seconds or multiples thereof. This is
usually caused by an algorithm failing to pass the self-test.
If an algorithm fails to be constructed, we will immediately notify
all larval waiters. However, if it succeeds in construction, but
then fails the self-test, we won't notify anyone at all.
This patch fixes this by merging the notification in the case
where the algorithm fails to be constructed with that of the
the case where it pases the self-test. This way regardless of
what happens, we'll give the larval waiters an answer.

This reverts commit 9e612a008f.
It incorrectly finds VGA connectors where none are attached, apparently
not noticing that nothing replied to the EDID queries, and happily using
the default EDID modes that have nothing to do with actual hardware.
That in turn then causes X to fall down to the lowest common
denominator, which is usually the default 1024x768 mode that is in the
default EDID and pretty much anything supports).
I'd suggest that if not relying on the HDP pin, the code should at least
check whether it gets valid EDID data back, rather than just assume
there's something on the VGA connector.

This reverts commit 7732a557b1 (and commit
3f50fff4da, which was a follow-up
cleanup).
We're chasing an elusive bug that Dave Jones can apparently reproduce
using his system call fuzzer tool, and that looks like some kind of
locking ordering problem on the directory i_mutex chain. Our i_mutex
locking is rather complex, and depends on the topological ordering of
the directories, which is why we have been very wary of splicing
directory entries around.
Of course, we really don't want to ever see aliased unconnected
directories anyway, so none of this should ever happen, but this revert
aims to basically get us back to a known older state.
Bruce points to some of the previous discussion at
http://marc.info/?i=<20110310105821.GE22723@ZenIV.linux.org.uk>
and in particular a long post from Neil:
http://marc.info/?i=<20110311150749.2fa2be66@notabene.brown>
It should be noted that it's possible that Dave's problems come from
other changes altohgether, including possibly just the fact that Dave
constantly is teachning his fuzzer new tricks. So what appears to be a
new bug could in fact be an old one that just gets newly triggered, but
