STATUS command, which makes the 'chio status' command fail.

Reverse the VFS_VRELE patch. Reference counting of vnodes does not need
to be done per-fs. I noticed this while fixing vfs layering violations.
Doing reference counting in generic code is also the preference cited by
John Heidemann in recent discussions with him.
The implementation of alternative vnode management per-fs is still a valid
requirement for some filesystems but will be revisited sometime later,
most likely using a different framework.

Support >8G drives in CHS mode. This is done by guesstimating the
cylinder count from the LBA size reported. It works on my shiny
new Maxtor 11.5G drive, YMMV.
Reports from users of other big drives (read Quantum bigfoot's)
are welcome...
Technologies' Socket 7 chipsets. This covers all of the Apollo chipsets
except the Master (82C570) and the MVP3, and it also covers the cheap
VXPro and VXTWO knockoffs of the VP1 and VPX.

the page offset. If a large file offset was passed in, a large negative
array index could be generated which could cause page faults etc at worst
and file corruption at the least. (Pages are allocated within file
space on page alignment boundaries, so a file offset being passed in here
is harmless to DTRT. The case where this was happening has already been
fixed though, this is in case it happens again).

[__]inline is only used to bloat the code here. It gives a separate copy

Fixed misuse of __P(()).
called from vfs_bio_awrite() without going through cluster_write()
or ufs_bmaparray(), in particular for all writes to block disk devices.
Only ufs_bmaparray() sets vp->v_maxio in a correct way, and it doesn't
seem to be called early enough even for regular files.
expecting a sub-page offset. We were passing the file position,
and vm_page_bits() could do some interesting things when base was
larger PAGE_SIZE.
if (size > PAGE_SIZE - base)
size = PAGE_SIZE - base;

this could have interesting consequences for memory page -> device block
bit validation.
necessary to compile with _THREAD_SAFE defined. This means that people
will get thread-aware code whether they like it or not. This change
is required to allow a process to link against libpthread and libc
to use kernel threads (and prevent each thread from clobbering another
thread's errno just be doing a syscall).
This is bound to break some ports, but it is strictly allowed by ANSI C,
so anything that breaks as a result was already broken anyway 8-).

Increase limit for maximum disk size: as far as I can see previous limit was
gratuitously too low.
