done with boot1 on the alpha. We use 4k buffers regardless of the
actual filesystem block size.
Remove the simple malloc() implementation, as it is no longer used.

MFC at: earliest convenience
detect 3.3V cards for the 6710 and another method for the 6722. This
latter method is also how the 6729/6730 is supposed to detect 3.3V
cards. This method works great on my Fujitsu Stylistic 500. Sadly,
it appears that not all laptop makers are as detail oriented as the
folks that made the Stylistic. IBM Thinkpad 701C and AST Asentia 810N
both hang hard when the 6729 method is used, but at least the thinkpad
works when the 6710 method is used. The failure mode appears to be any
access to the memory that we've mapped the CIS in causes the machine to
hang until you eject the card. The Thinkpad, at least, works with this
change, and it doesn't break my Stylistic.

block sizees larger than 8192 bytes have been resolved, as per the
following deltas:
rev 1.34 src/sys/boot/i386/boot2/boot2.c
rev 1.5 src/sys/boot/alpha/boot1/sys.c
than necessary.
o Move a rarely-used goto label inside a critical section so that we don't
perform an splnet() for which there is no corresponding splx().
o Remove unnecessary splnet()/splx() around accesses to kaioinfo::kaio_jobdone
in aio_return().
o Use TAILQ_FOREACH for simple cases of iteration over kaioinfo::kaio_jobdone.
functions just grab f_data and don't muck with anything else so this
should be ok.
this fixes a panic with invariants where it thinks we've doubly initialized
the filetmp mutex even though all we've done is neglect to bzero it.
vfs.nfs.iodmaxidle (idle time before nfsiod's exit). Make it adaptive
so that we create nfsiod's on demand and they go away after not being
used for a while. The upper limit is NFS_MAXASYNCDAEMON (currently 20).
More will be done here, but this is a useful checkpoint.

which was causing the link of the kernel to fail. Since layer4/i4b_l4mgmt.c
is always required by i4b and layer3/i4b_q931.c is only needed when a
passive card is present it makes sense to have the declaration in the
former file only.
No MFC required since the problem only became apparent after a change to
the compile options in -current which AFAIK wasn't made in -stable.
Seigo Tanimura (tanimura) posted the initial delta.
I've polished it quite a bit reducing the need for locking and
adapting it for KSE.
Locks:
1 mutex in each filedesc
protects all the fields.
protects "struct file" initialization, while a struct file
is being changed from &badfileops -> &pipeops or something
the filedesc should be locked.
1 mutex in each struct file
protects the refcount fields.
doesn't protect anything else.
the flags used for garbage collection have been moved to
f_gcflag which was the FILLER short, this doesn't need
locking because the garbage collection is a single threaded
container.
could likely be made to use a pool mutex.
1 sx lock for the global filelist.
struct file * fhold(struct file *fp);
/* increments reference count on a file */
struct file * fhold_locked(struct file *fp);
/* like fhold but expects file to locked */
struct file * ffind_hold(struct thread *, int fd);
/* finds the struct file in thread, adds one reference and
returns it unlocked */
struct file * ffind_lock(struct thread *, int fd);
/* ffind_hold, but returns file locked */
I still have to smp-safe the fget cruft, I'll get to that asap.
Clarify comment about kind of color emulators for which vt*-co* entries
are for and about saving space.
Use direct \E[m instead of ...;m for dumb emulators.
