libcam/Makefile: Add scsi_da.c to libcam for the new
scsi_format_unit() function.
camcontrol.8: Update the man page for the new format
functionality, and take out the examples section
describing how to do it with 'camcontrol cmd'.
camcontrol.c: New format functionality. Note that unlike the
rest of the camcontrol subcommands, this one is
interactive by default. Because of the potential
destructiveness of the format command, I thought
it necessary to get confirmation from the user
before spamming a disk. You can disable the
interactive behavior, and the status meter with
command line arguments.
scsi_da.c: Add the new scsi_format_unit() cdb building
function and use #ifdef _KERNEL to make this file
compile in both the kernel and userland. The
format unit function is currently only defined in
the non-kernel case, because nothing in the kernel
is using it. If that changes, it should be
un-ifdefed and compiled in both cases.
scsi_da.h: New function declaration, CDB structure and format
data structures.
Thanks to Nick Hibma for providing some valuable input on these changes.
various architectures. Now all the work is done in crtbegin.c.
It doesn't contain any assembly language code, so it should work
fine on all architectures. (I have tested it on the i386 and the
alpha.) The old assembly language files crt[in].S are now empty
shells that generate no code or data. They should not be removed
any time soon, because the various versions of gcc in src and ports
expect them to exist.
Next I will move crtbegin.c into a new common machine-independent
directory, and adjust the i386-elf Makefile to use that version.
After that I will adjust the alpha Makefile to use the common
version too.

was not the fault of the module code, nor FICL. The malloc code requires
sbrk() to return addresses that were at least 16 byte aligned. If the
Alpha loader happened to be 8 byte but not 16 byte aligned in length, then
you would get a zfree() panic at startup.
Incidently, this affected the i386 loader as well, and explains why
the static heap changed things and why jlemon had trouble when the bss
was not ending at a multiple of 8 bytes.
My fix is to 16 byte align it on all arches, even though the x86 version
only required 8 byte alignment (struct MemNode is smaller there). We could
page align it if we wanted to be paranoid, but it isn't presently necessary.
