Please review the sparc64 bugs in the kernel Bugzilla

Hi,

the kernel Bugzilla [1] currently contains 8 open [2] sparc64 bugs.

Can you review them (some might require to first ask the submitter 
whether they are still present in recent kernels)?

It's not a good thing that even issues like #2683 stayed unanswered for 
a long time.

TIA
Adrian

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
