[GIT] Sparc

[David Miller]

This fixes two bugs.

First a fix from Daniel Hellstrom that eliminates a hard-coded HZ
constant in the LEON code.

Second, fix a regression in sparc64 firmware calls.

Some kinds of firmware calls are not safe to pass buffer addresses
over 4GB, they really aren't 64-bit safe universally especially on
older sparc64 systems.

So I fixed this in two steps:

1) Remove firmware interfaces unused by the kernel right now, which is
   safer than trying to recode them to use bounce buffers or similar.

2) Add a bounce buffer for PROM console writes to ensure that the
   buffer restrictions are met.

Tested successfully by the original bug reporter.

Please pull, thanks a lot!
