70bad4f75b If we are asked to print the total number of blocks, do so even if we
have no entries to print (either due to an empty directory or an
error).  This makes the -l and -s options more consistent, like
Solaris and (Debian) Linux.  To make this happen, tweak two
optimizations on the second call to display():

- Don't skip display() altogether, even if list == NULL.
- Don't skip the call to the printfn in display() if we
  need to print the total.

1e03bff7f2 In fts_build(), if we try to chdir and fail (e.g. due to lack of search
permission), try to continue in FTS_DONTCHDIR mode.  Of course this
won't work for long paths, but we can't descend more than one pathname
component beyond the directory anyway if we lack search permission.

Here is a transcript demonstrating the change, where oldls is ls(1)
linked with the old fts(3):

	das@VARK:~> mkdir t && touch t/{a,b,c} && chmod u-x t
	das@VARK:~> oldls t
	a       b       c
	das@VARK:~> oldls -l t
	das@VARK:~> \ls t
	a       b       c
	das@VARK:~> \ls -l t
	ls: a: Permission denied
	ls: b: Permission denied
	ls: c: Permission denied

I had forgotten about this patch until bde reminded me.  He reports

92a5b2ee71 Rename cantwrite() to prepwrite(). The latter is less confusing,
since the macro isn't really a predicate, and it has side-effects.
Also, don't set errno if prepwrite() fails, since this is done in
prepwrite() now.

325d97d0d1 Set errno to EBADF on attempts to write to a stream that is not
writable.  Affected callers include fwrite(), put?(), and *printf().
The issue of whether this is the right errno for funopened streams is
unresolved, but that's an obscure case, and some errno is better than
no errno.

591506d322 In pmap_extract_and_hold(), there is no need to mask off PG_FRAME because
pmap_extract() already does it.
In pmap_enter(), opa has already been masked so don't do it again.
Wrap a long line (recent transgression).
Use trunc_page() in pmap_mapdev() instead of anding with PG_FRAME, since
that is what we really meant.

430e272c7e Initial PG_NX support (no-execute page bit)
- export the rest of the cpu features (and amd's features).
- turn on EFER_NXE, depending on the NX amd feature bit
- reorg the identcpu stuff a bit in order to stop treating the
  amd features as second class features (since it is now a primary feature
  bit set) and make it easier to export.

7d95d34bb7 Mask pte's with PG_FRAME before passing it to PHYS_TO_VM_PAGE().. PG_NX
lives in the top 12 'available' bits.  atop() in the PHYS_TO_VM_PAGE()
macro only masks off the lower bits (by accident) and the upper bits
in the 64 bit ptes turn into "interesting" index values.

c2490f2dfb Fix a serious problem that manifested during swap, and a few other times.
pmap_remove() would be called with a huge range and we'd stride across
it in only 2MB chunks.  This would manifest as massive cpu time and a
largely unresponsive system during hard swap.  Instead, check the higher
page directories which means we can run pmap_remove() in just a few
hundred loop iterations instead of millions since we can process
address space in chunks of 512GB and 1GB as well as 2MB.

aa57bb0424 Correct a resource leak introduced in recent accept locking changes:
when I reordered events in accept1() to allocate a file descriptor
earlier, I didn't properly update use of goto on exit to unwind for
cases where the file descriptor is now held, but wasn't previously.
The result was that, in the event of accept() on a non-blocking socket,
or in the event of a socket error, a file descriptor would be leaked.

This ended up being non-fatal in many cases, as the file descriptor
would be properly GC'd on process exit, so only showed up for processes
that do a lot of non-blocking accept() calls, and also live for a long
time (such as qmail).

This change updates the use of goto targets to do additional unwinding.

45e556cc69 Avoid printing extraneous warning messages when trying to switch a device
which doesn't support ACPI power states.  Return AE_NOT_FOUND for these
cases and don't print the warning message.  Also, print the name of the
handle instead of device when unable to switch states.  The device is often
not attached at this point and so its name is NULL, which doesn't help
debugging.
