7d55aa8a32 rio: properly restore the windows contents on /dev/mouse close
The previous resize optimization now means that the wfill()
is skipped on resize for libdraw programs.

So do it once /dev/mouse is closed and the window processes
the Refresh message.

2652cbee57 proof: don't confuse ""(1) (thanks Stuart Morrow)
"" looks for patterns in the form 'prompt;' or 'prompt%',
and gets confused when proof emits 'illegal;'. This change
replaces the ';' with a ':', which both matches other
conventional error outputs and prevents "" from getting
confused.

07e8c324a8 tmdate(2): remove lies
Initially the code tried to guess the date format. This
turned out to be a bit too magical, so the feature was
removed, but the manpage still documented the nonfeature.

c931e96364 rio: avoid redrawing window text on resize for programs using libdraw
As long as the client as the mouse file open
and maintains reading the winname file of the window
after a resize we will avoid drawing the text frame
on a resize as it will be overdrawn by the client.

This reduces flicker on resize somewhat for slow systems.

1d93a5628a pc, pc64, xen: rewrite interrupt handling code
This implements proper intrdisable() support for all
interrupt controllers.

For enable, (*arch->intrassign)(Vctl*) fills in the
Vctl.enable and Vctl.disable pointers with the
appropriate routines and returns the assigned
vector number.

Once the Vctl struct has been linked to its vector
chain, Vctl.enable(Vctl*, shared) gets called with a
flag if the vector has been already enabled (shared).

This order is important here as enabling the interrupt
on the controller before we have linked the chain can
cause spurious interrupts, expecially on mp system
where the interrupt can target a different cpu than
the caller of intrenable().

The intrdisable() case is the other way around.
We first disable the interrupt on the controller
and after that unlink the Vctl from the chain.
On a multiprocessor, the xfree() of the Vctl struct
is delayed to avoid freeing it while it is still
in use by another cpu.

The xen port now also uses pc/irq.c which has been
made generic enougth to handle xen's irq scheme.
Also, archgeneric is now a separate file to avoid
pulling in dependencies from the 8259 interrupt
controller code.

2a907fd459 games/mix: fix implementation of MOVE instruction (thanks nicolagi)
Plan 9 memcpy(2) uses the same implementation as memmove(2) to handle
overlapping ranges.  Hovewer, the MIX MOVE instruction, as described
in TAOCP, specifically does not do this.  It copies words one at a
time starting from the lowest address.

This change also expands the address validation to check that all
addresses within the source and destination ranges are valid before
proceeding.

bd6747ccd0 upas/*: fix mkfile issues (thanks amavect)
Fixes 3 issues in our upas mkfiles:
- mk/mkfile and send/mkfile were rebuilding
  only the rfc822.tab.$O, even though the
  header also needed to be rebuilt.
- CLEANFILES had a pattern that  would not
  get expanded.
- Third, ../upas/mkfile was being included
  in the wrong place and making the wrong
  rule default.

97008caa41 g: filter directory arguments
When searching directories recursively, it's still
desirable to filter the contents by the file pattern,
so that 'g foo /sys/src' doesn't end up searching for
foo within .$O files.

Files passed explicitly are still searched, so for the
old behavior, just use walk:

	g foo `{walk -f $dir}

d1dc287210 9boot(8): update manual to reflect efi loader search order changes

486ce60546 efi: prefer plan9.ini from ESP we loaded from
currently the EFI loader's behavior is to search all disks in a
firmware-defined order.  we search the list returned by the firmware
in reverse order in the hopes of searching the first 9FAT instead of
the ESP, but this results in unintuitive behavior when there are
multiple FAT partitions (possibly in multiple disks), such as loading
a plan9.ini and kernel from a different disk than the one you executed
the EFI loader from.

to resolve this, we change the EFI loader to instead prefer read
plan9.ini and the kernel from the same disk as the EFI loader was read
from, and then fall back to the old behavior, since the old behavior
is relied on by current installations.

ad9b1234c3 dc: fix crashes with : operator (thanks istvan bak)
dc crashes because a Blk* sometimes ends getting double freed.
To make it crash, any of these lines will do:
(each line is a separate input to dc):

1 sa 2 :a le d sa v :a
1 sa 2 :a le d sa :a
1 sa 2 :a le d sa c

Fix by assigning p to sptr->val before EMTPY causes a jump.

Additionally, dcgetwd() can return 0. all other uses check for
0 ptr; Also fix a buffer overflow.

b438fd9d09 ether8169: fix interrupt panic before init, defer initialization until attach
The driver used to register the interrupt handler just
after reset, tho the Ctlr struct, including the buffer
descriptor arrays where only allocated on attach.

This moves most of the reset/init out of pnp
function and into attach. This also means we can
error out and even retry on the next attach.

The logic of the reseter kproc has been changed:
now it is only started once the first initialization
completely succeeded. This avoids the strange qlock
passing.

Implement a shutdown function so the device gets
halted for /dev/reboot.

Assume 64 bit physical addresses for dma.

Check that pci bar0 is actually I/O.

ef2fdb6fdd awk: fix truncated input after fflush
Before the "native" awk work, a call to the fflush function resulted
in one or more calls to the APE fflush(2).

Calling fflush on a stream open for reading has different behavior
based on the environment: within APE, it's a no-op¹; on OpenBSD, it's
an error²; in musl, it depends on whether or not the underlying file
descriptor is seekable³; etc. I'm sure glibc is subtly different.

Now that awk uses libbio, things are different: calling Bflush(2) on a
file open for reading simply discards any data in the buffer. This
explains why we're seeing truncated input. When awk attempts to read
in the next record, there's nothing in the buffer and no more data to
read so it gets EOF and exits normally. Note that this behavior is not
documented in bio(2). It was added in the second edition but I haven't
figured out why or what depends on it.

The simple fix is to have awk only call Bflush on files that were
opened for writing. You could argue that this is the only correct
behavior according to the awk(1) manual and it is, in fact, how GNU
awk behaves⁴.
