always print an error message. If bootable and -v flag was
specified, print a success message. If -v flag was specified
more than once, also try to decode more information from
the PBR.
Input from dsl and bad.
fdc0 at isa? don't have a fdc at all). Because of the 'fdc0 at isa?', on
systems supporting ACPI the floppy controller would attach as fdc1. as fd(4)
looks for its type in nvram using the floppy controller index, it's looking for
the wrong controller and the default density isn't set (so /dev/fd0a doens't
work).
Problem analyzed by John Nemeth, thanks !
- Remove unused debug and progname variables
- Use return instead of exit() for quiting at end of main()
- Print errors to stderr instead of stdout

(hfslib_open_volume) We are only interested in the catalgo and
extents header, so read the first 512 bytes, not the whole first
extent. Also makes mounting a lot faster.
Rewrite the ARM mutex implementation to be of the simple-mutex variety.
Because pre-v6 ARM lacks support for an atomic compare-and-swap, we
implement _lock_cas() as a restartable atomic squence that is checked
in the IRQ handler right before AST processing. (This is safe because,
for all practical purposes, there are no SMP pre-v6 ARM systems.)
This can serve as a model for other non-MP platforms that lack the
necessary atomic operations for mutexes (SuperH, for example).
Upshots of this change:
- kmutex_t is now down to 8 bytes on ARM; about as good as we can get.
- ARM2 systems don't have to trap and emulate SWP or SWPB for mutexes.
The acorn26 port is not updated by this commit to do the LOCK_CAS_CHECK.
That is left as an exercise for the port maintainer.

Since I managed to commit my alternate scheme for zeropad, delete
the commented out lines and replace the only other use.
I've not deleted the function itself though.
