- physmap_map, physmap_map_fini: pmap_update() must be performed before
  freeing the VA; otherwise there is a window when it can be re-used while
  stale TLB entries may be present.
- physmap_fill: use MIN() instead of min(), since vsize_t is used.
- Add RCS ID comment while here and prevent physmap.h inclusion in userland.
Add !defined(KMEMUSER)
Sort options in SYNOPSIS and text.
XXX: please check if SYNOPSIS are correct, I think they missing some .Op.
meta_oodate: rename ignoreOODATE to needOODATE.
if target uses ${.OODATE} in its script;
1. we canno compare commands
2. if we decide it is out-of-date .OODATE must not be empty.
   The only option is to set it to .ALLSRC
Use PR_NOWAIT in dwc_otg_allocx as it can be called in the USB softint via
completions.
mktime(3) works in local time, and trying to trick it by
setting tm_gmtoff doesn't work.  Instead, call mktime_z(3)
with a null timezone (so it works in UTC) and adjust the
result afterwards.  Now "date -d @0" correctly
prints the local equivalent of 1970-01-01 00:00:00 UTC.
Add -d as a synonym for getting into DDB to match other ports.
Avoid warning from cngetc byt doing the proper cnpollc dance
Document the fact that ctime_rz, localtime_rz, and mktime_z,
accept a NULL timezone_t pointer as a reference to UTC,
and the fact that tzalloc accepts a NULL zone name.
* Test that parsedate("@0", ...) returns (time_t)0 regardless of timezone.
* Test that parsedate("@-1", NULL, NULL) returns (time_t)-1
  without setting errno.
Don't count bit0 events in gintsts. bit 0 tells us which mode we're in
0 = device, 1 = host
oops, disable the counters by default
Whitespace
Compile fix
Rename the GRXSTSP registers and don't print the "pop" version.
Improve some DIAGNOSTIC stuff
Pay attention to the return value from cv_wait_sig as well in
usbd_transfer.  hi christos.
Test parsedate("@-2",...) (should return -2 and not set errno);
and parsedate("@junk",...) (should return -1 and set errno).
We were already testing "@-1".
Distinguish between a non-error result of (time_t)-1 and an error result.
Modernise the test code inside #ifdef TEST.
Fix typo.
