f48f1a324a bcm: use extended small pages so XN bit can work 
the change to support no-execute bits broke the original
raspberry pi1, as it uses backwards compatible page table
format.

to use the XN bit, subpage AP bits have to be disabled
using the XP bit in CP15 Control Register c1 Bit 23.

7c55ca5fff acme: Apply each -/+ only once (#156) 
When plumbing an address like `3-`, Acme selects line 1,
and similarly `3+` selects line 5.
The same problem can be observed for character addresses (`#123+`)
but _not_ for ones like `+`, `.+` or `/foo/+`:
The problem only occurs when a number is followed by a direction (`-`/`+`).

Following along with the example `3-` through `address` (in addr.c):
We read `3` into `c` and match the `case` on line 239.
The `while` loop on line 242ff reads additional digits into `c`
and puts the first non-digit back by decrementing the index `q`.
Then we find the range for line 3 on line 251 and continue.

On the next iteration, we set `prevc` to the last `c`,
but since that part read ahead _into `c`_,
`c` is currently the _next_ character we will read, `-`,
and now `prevc` is too.

Then in the case block (line 210) the condition on line 211 holds
and Acme believes that it has read two `-` in sequence
and modifies the range to account for the “first” `-`.
The “second” `-` gets applied after the loop is done, on line 292.

So the general problem is:
While reading numbers, Acme reads the next character after the number into `c`.
It decrements the counter to ensure it will read it again on the next iteration,
but it still uses it to update `prevc`.

This change solves the problem by reading digits into `nc` instead.
This variable is used to similar effect in the block for directions (line 212)
and fills the role of “local `c` that we can safely use to read ahead” nicely.

5d59a44c21 pc, pc64: clear debug watchpoint registers on exec and exit 
when a process does an exec syscall, procsetup() is called and
we have to disable the debug watchpoint registers. just clearing
p->dr is not enougth as we are not going thru a procsave() and
procrestore() cycle which would disable and reload the saved
debug registers.

instead of clearing debug registers in procfork(), we should
clear the saved debug registers before a process goes to die
(pexit() calls sched() with up->state = Moribund) as the Proc
structure can get reused for kernel processes (kproc) which
never call procfork() and would therefore have debug registers
loaded.

b2526c7d90 simplify flag parsing. 
we've only got a few flags, a linear search is good enough,
and is obviously correct; the old search wasn't.

08d6b0f043 kernel: improve diagnostics by reversing the roles of Proc.parentpid and Proc.parent 
for better system diagnostics, we *ALWAYS* want to record the parent
pid of a user process, regardless of if the child will post a wait
record on exit or not.

for that, we reverse the roles of Proc.parent and Proc.parentpid so
Proc.parentpid will always be set on rfork() and the Proc.parent
pointer will point to the parent's Proc structure or is set to nil
when no wait record should be posted on exit (RFNOWAIT flag).

this means that we can get the pid of the original parent process
from /proc, regardless of the the child having rforked with the
RFNOWAIT flag. this improves the output of pstree(1) somewhat if
the parent is still alive. note that theres no guarantee that the
parent pid is still valid.

the conditions are unchanged:

a user process that will post wait record has:

up->kp == 0 && up->parent != nil && up->parent->pid == up->parentpid

the boot process is:

up->kp == 0 && up->parent == nil && up->parentpid == 0

and kproc's have:

up->kp != 0 && up->parent == nil && up->parentpid == 0

21a599743e pc, pc64: merge adjacent e820 map entries of same type 
some machines give us over 300 e820 ram entries that are
all adjacent to each other causing us to run out of Map
end Emap entries.

this change adds e820clean() function, which sorts the
current e820 map and discards unusable entries and merges
adjacent entries. e820clean() is called after we parsed
the *e820= boot parameter or when we run out of entries.

an example of such a broken e820 map (thanks mischief):

2359389570 os(1): add c implementation of inferno os command and cmd(3) device manpages 
this is a reimplementation of infernos os(1) command, which
allows running commands in the underhying host operating
system when inferno runs in hosted mode (emu). but unlike
inferno, we want to use it to run commands on the client
side of a inferno or drawterm session from the plan9 cpu
server, so it defaults to /mnt/term/cmd for the mountpoint.

37d6ddd8f3 rio(4): update description of wctl file format 
State strings are now padded to 12-characters.  Remove ambiguous
reference to "12-character style", instead referring the reader to
image(6).

4d4107b385 rio: fix bug causing short reads of wctl files 
Previously, reads of wctl files would return one byte less than
requested as the returned string must be null terminated.  Now we pass
the actual size of the allocated buffer to the handler, which is large
enough to accommodate a trailing partial rune and terminating null
byte.
