According to the Linux sungem driver, in case of Apple (K2) GMACs
GEM_MIF_CONFIG_MDI0 cannot be trusted when the firmware has powered
down the chip so the internal transceiver has to be hardcoded. This
is also in line with the AppleGMACEthernet driver, which just doesn't
distinguish between internal/external transceiver and MDIO/MDI1
respectively in the first place. Tested by: Andreas Tobler

- The OPSZ macro actually only does the right thing for int32 and int64
operands but not for double and extended double ones. Instead of trying
to fix the macro just nuke it and unroll the loops in the correct way
though as extended double operands turn out to be the only special case.
- For FxTO{s,d,q} the source operand is int64 so rs2 has to be re-decoded
after setting type accordingly as it's generally decoded using the low
2 bits as the type, which are 0 for these three instructions.
- Similarly, in case of F{s,d,q}TOx the target is int64 so rd has to be
re-decoded using not only the operand mask appropriate for int64 but
also the correct register number encoding.
- Use const where appropriate.
- Wrap long lines.

MFC r204410: Include terminated threads in ps's process cpu time field.
When a kinfo_proc is filled, first fill_kinfo_proc_only() fills in
ki_runtime using p->p_rux.rux_runtime (all cpu time used by the process
including terminated threads). If information for a specific thread is
requested, fill_kinfo_thread() then overwrites this with the thread's
td->td_runtime (good). If not, fill_kinfo_aggregate() overwrote it with
the sum of all threads' td->td_runtime which does not include terminated
threads.
This affects ps(1)'s TIME field, not its %CPU field nor anything in

MFC r203760: Improve time precision for grdc(6):
Traditionally, grdc would obtain time through time(3) which in turn gets
only the second part of clock (CLOCK_SECOND), and sleep for 1 second after
each screen refresh.
This approach would have two problems. First, we are not guaranteed to
be waken up at the beginning of a whole second, which will typically
exhibit as a "lag" on second number. Second, because we sleep for whole
second, and the refresh process would take some time, the error would
accumulate from time to time, making the lag variable.
Make grdc(6) to use time(3) to get time only at the beginning, and sample
time in CLOCK_REALTIME_FAST granularity after refreshing, and use the
nanosecond part to caculate how much time we want to sleep.
