o Add bootinfo support by checking the fifth and sixth arguments for a
...
magic number and a pointer to the bootinfo data.
XXX: A bootinfo_magic record is not checked for at the moment, even
though test bootblocks initialise the bootinfo data with one.
o Use the bootinfo symtab information in preference to searching for a
valid a.out exec header after _end for initialising DDB.
XXX: Should retire a.out exec header support altogether. Loosing the
ability to load symbols from old bootblocks isn't much of a loss.
After 1.4?
o Add "booted kernel" machdep sysctl.

If on entry the stack is within 4kB of _start, don't reset the stack

pointer to just underneath _start. Allows bootblocks (or other kernel

The 4kB figure may be overkill - on the pmax it only needs to be a dozen

The ARM has the same copy-on-write bug as the i386 -- the write enable bit in

destination pages.

Repeat after me:

If we're doing modified bit emulation, we must revoke write permission in
pmap_clear_modify(). This is non-negotiable. I will revoke write permission
in pmap_clear_modify(), or suffer the wrath of a thousand bricks.
