A few sparc64 bug fixes and proper 64-bit rwsem support as you
suggested.
1) Fetching large device properties from openfirmware spams all
over the kernel data section, based upon a report by Meelis
Roos. The fix is to just use the caller's buffers directly
instead of this unnecessary 3k bounce buffer business.
2) The atomic64_t interface 'long' cases I missed.
3) Lock loop backoff didn't really NOP out correctly on UP.
4) Perf control register writes would write the register
twice by mistake due to a missing delay slot nop. Fix
from Mikulas Patocka.
Please pull, thanks a lot!
