Umm? I am afraid I have been describing it badly. This random
SIGBUS+SIGSEGV problem is new - I have not seen it before.

I have been able to do kernel compiles for years on sparc64 (modulo
specific bugs in specific configurations) and 3.17 + start/end swap
patch seems also stable for most machine. With yesterdays git + align
patch, it dies with SIGBUS multiple times during compilation so it's a
new regression for me.

Will try reverting that commit tomorrow.

My only other current sparc64 problems that I am seeing - V210/V440 die
during bootup if compiled with gcc 4.9 and V480 dies with FATAL
exceptions during bootups since previous kernel release. Maybe also
exit_mmap warning - I do not know if they have been fixed, I see them
rarely.
