frequency in the at91_pmc_clock_init rather than passing it in. Allow
for frequencies >= 21MHz by rounding to the nearest 500Hz (Idea from
Ian Lapore whose company uses a similar arrangement in their product).
at91_pmc_clock_init() is now nearly independent of the rest of the pmc
driver (which means we may be able to call it much earlier in boot
soon to eliminate the master clock config file requirement for printf
to work during early boot and also eliminate some interdependencies
with the device ordering which requires pmc to be the first device
added).
to this pmap.c. This new r/w lock is used primarily to synchronize access
to the PV lists. However, it will be used in a somewhat unconventional
way. As finer-grained PV list locking is added to each of the pmap
functions that acquire this r/w lock, its acquisition will be changed from
write to read, enabling concurrent execution of the pmap functions with
finer-grained locking.

The generic ELF loading code maps the kernel into low memory
by subtracting KERN_BASE. So the copyin/copyout/readin functions
are always called with low addresses. This code finds the largest
DRAM block from the U-Boot memory map and adds that base to
the addresses.
In particular, this fixes ubldr on AM3358, which has DRAM
mapped to 0x80000000 at power-on.

This should fix the problem which kernel never response to the sleep

range operations like pmap_remove() and pmap_protect() as well as allowing
simple operations like pmap_extract() not to involve any global state.
This substantially reduces lock coverages for the global table lock and
improves concurrency.
casted to structs by getting rid of these buffers entirely. In r169832, it
was tried to paper over this issue by 32-bit aligning the buffers. Depending
on compiler optimizations that still was insufficient for 64-bit architectures
with strong alignment requirements though.
While at it, add comments regarding the total lack of locking in this area.

There's some TX path TDMA code in if_ath_tx.c which should be migrated
out, but first I should likely try and verify/fix/repair the TDMA support
in 9.x and -HEAD.
* migrate the rx processing out into if_ath_rx.c
* migrate the TSF functions into if_ath_tsf.h, as inlines
This is in prepration for supporting the EDMA RX routines, required to
support the AR93xx series NICs.
TODO:
* ath_start() shouldn't be private, but it's called as part of
the RX path. I should likely migrate ath_rx_tasklet() back into
if_ath.c and then return this to be 'static'. The RX code really
shouldn't need to see TX routines (and vice versa.)
* ath_beacon_* should be in if_ath_beacon.[ch].
* ath_tdma_* should be in if_ath_tdma.[ch] ...
Allow tso4 and tso6 be set individually given we have the bits.
This will help with drivers not working as expected during the
transition time and later.

Introduce dirfd() libc exported symbol replacing macro with same name,
preserve _dirfd() macro for internal use.
Replace dirp->dd_fd with dirfd() call. Avoid using dirfd as variable
