8f5067ba28 Make printf() a bit more robust and allow NULL strings (print them as 
"<null>"). It bad to have diagnostic printfs cause panics when they are
trying to tell you about another problem.

e4bebee03e Use the same current time throughout ITIMES(). I want all current 
timestamps for an atomic operation such as rename() on a local file
system to be identical.

Uniformize yet another idempotency ifdef.  The comment nesting was
bogus.

a176f73d19 Fix panic for `cp -p' by root to an msdos file system. Improve handling 
of attributes so that `cp -p' to an msdos file system can succeed under
favourable circumstances (no uid or gid changes and no nonzero flags
except SF_ARCHIVED).

msdosfs_vnops.c:
The in-core inode flags were confused with the on-disk inode flags, so
chflags() clobbered the lock flag and caused a panic.

denode.h, msdosfs_denode.c, msdosfs_vnops.c:
Support the msdosfs archive attibute (ATTR_ARCHIVE) by mapping it to
the complement of the SF_ARCHIVED flag and setting the ATTR_ARCHIVE
bit when a file's modification time is set (but not when a file's
permissions are set; this is the standard wrong DOS behaviour).

denode.h, msdosfs_denode.c:
Remove the DE_UPDAT() macro.  It was only used once, and the corresponding
macro in ufs has already been removed.

denode.h:
Don't change the timestamp for directories in DE_TIMES() (be consistent
with deupdat()).

msdosfs_vnops.c:
Handle chown() better: return EPERM instead of EINVAL if there are
insufficient permissions; otherwise, allow null changes.

11fa0751bc Fix the "wd" count stat. The seek and xfer stats are still very bogus 
for wd (they both count the number of sectors).  The wpms stat is still
moderately bogus for all drivers.  Even the count stat could be handled
better (partial blocks should be counted as full blocks; should errors
and retries be counted?).

e72e8750d3 Insert a hook to initialize the serial port at the beginning of 
boot().  This is needed so the "serialboot" stuff can share this file,
too.

Everything is #ifdef'ed so it evaluates to nothing when actually been
built in the "biosboot" directory.

2c681fc102 This became a frequently requested item now. 
The files in this directory are modified version of "biosboot".  The
only difference is in that they perform their I/O via a serial port,
so their preferrable usage is to form bootblocks for systems where the
kernel happens to have an "options COMCONSOLE".  Most of the code is
actually shared with "biosboot", and make will not (and should not)
descend into this directory by default.  It is in the responsibility
of the user to build these bootblocks instead of the original ones.
