Add awinrtc.  Hi Jared.
Adapt formats for debug printfs to clock_subr type changes.
use dma for mmc data transfers
awinmmc(4): Use DMA for MMC transfers.
awinrtc(4): Add support for AllWinner A10/A20 real-time clock.
Revert 1.33 and 1.34 for now, until either .INVISIBLE is reinstanciated
or random.S dropped.
Add work-in-progress driver for the Designware GMAC core, found on some
allwinner chips.
Config glue for the Designware GMAC core.
Switch allwinner specific awge driver over to use it.
Store symlinks without a NUL terminator so that lstat(2) returns the
correct length.  Fixes the tmpfs part of PR kern/48864.
PR/49185: Conrad Meyer: strvisx: Handle zero-length input strings gracefully.
(don't abuse 0 to mean compute string length internally)
get rid of MB_STRZ as suggested by joerg.
Always use cprng_fast32, even during initialisation. No point in using
random(9).
Timestamps are bad sources of entropy, so just use cprng_fast32.
add null and empty tests.
Add rgephy.
Prefer cprng_fast32 over random. A good distribution even in the lower
bits beat any minor performance advantage randomo(9) might have,
especially given the disk IO involved.
Replace random with cprng_fast32. Reorganise computation to replace
(32bit) division with (long) multiplication.
With PMAP_NEED_ALLOC_POOLPAGE, before using pmap_map_poolpage make sure
the page comes from the same freelist that pmap_map_poolpage uses.
eliminate most of the polling from awin_mmc_exec_command
add BUFQ_PRIOCSCAN
