Hi Dave!
I just had a closer look at the sunhv driver over the issue with
the device name mismatching in /proc/consoles and below /sys [1].
The name mismatch actually seems a regression which was introduced
with:
commit d5a2aa241aa0babf382d42d6033b30a5112e4c1e

[SPARC64] sunhv: Bug fixes.
Add udelay to polling console write loop, and increment
the loop limit.
Name the device "ttyHV" and pass that to add_preferred_console()
when we're using hypervisor console.
Kill sunhv_console_setup(), it's empty.
Handle the case where we don't want to use hypervisor console.
(ie. we have a head attached to a sun4v machine)

This commit change the name field in the sunhv_console struct but not
in the sunhv_reg struct. Would it be okay when I send a patch to
fix this inconsistency and match the name in sunhv_reg with the one
in sunhv_console?
Without the fix, it's not possible to determine the serial console
device from /proc/consoles. This mismatch does not exist for other
SPARC serial hardware and hence code like debian-installer's "stealtty"
works correctly on these but not on SUN4V with the sunhv driver.
