I haven't talked to Sam, I had forgotten about that - this will only break
ABI compat on -HEAD. "-mcmodel=medlow" was almost certainly never needed,
its an optimization that reduces then number of instructions needed to load
a constant by assuming that the constant is <=32 bits. Loading a 32 bit
constant is 3 instructions, loading a 64-bit constant is 7 :-(. Considering
the other performance issues that sparc64 has, its safe to say that the
extra overhead is in the noise.

Hi Kip,
could you please update the comment above the line you changed
as appropriate?
Do you have an idea why medlow no longer is crucial in order
to get a working kernel?
Did you talk to sam@ regarding providing a new sparc64 HAL BLOB
(according to sys/contrib/dev/ath/public/sparc64-be-elf.inc it
was built with -mcmodel=medlow, too)?
