04729d8900 execve_runproc: Correct thinko in Rev. 1.386; the new SP always points to 
after (higher adderss) argc/argv/env/aux/strings regardless of stack growing
direction .  Machines with grow-up stack will detect the top of
argc/argv/env/aux/strings by the address of *argv[] via ps_strings:ps_argvstr.

This means that old comments about RTLD_GAP are all obsolete.

With help from Nick Hudson.

91dff1f8f3 revarprequest: Avoid leaking mbuf. 
In revarprequest, an mbuf could perhaps be leaked in an error path.
My reading of the code is that this is not possible, because ar_pro is
set to ETHERNET_IP, and ar_tha can only be null in the 1394 case.
But, better to have the free call anyway; ar_tha does not have a
documented interface contract :-)

Pointed out by Maxime Villard.

763d7b32d6 execve_runproc: Unbreak __MACHINE_STACK_GROWS_UP machines. Clarify the stack 
address allocation code.  Summarize an awful big comment about the _rtld()
"gap".

(The log message in Rev. 1.384 was wrong; the new stack address is passed
not via the 3rd register argument, but via the SP.  The 3rd is for ps_strings.)

4282002059 execve_runproc: The stack address passed to the newly execve()'ed process, 
via the 3rd register argument, always points to the stack base address (==
minsaddr (min stack address) + ssize (stack size)).  Clarify that.

7a138543c8 Fix a botch on switching from apci (and dca) to MI com(4) 10 years ago. 
I.e. fix apci device address per FRODO_BASE macro change
in frodoreg.h rev 1.2.  Now bootloader works with serial console
on HP425e (which has only com at frodo).

Thanks to miod@openbsd for providing his 425e.

5c53644782 Address PR/48710. 
r3 is not trashed during the routine so the level is preserved.
The only two real bugs was not initializing r3 to 0 to start with L1 cache
and the invalid fetching the set count from r3.  The mov r1, #0 should have
been mov r3, #0 and has been corrected.
Instead of two shifts, just use ubfx to extract the set bits and then compare
them to 0.
Add some other minor optimizations that make the code a little clearer.
