I tested the merged sparc64 fixes in current git.
V100: with hugetlb, looping git clone still hangs the machine. RED state on reboot has changed - before it gave the trace on reboot and continued, now it contonues looping with the trace indefinitely, gcc 4.6.4
Netra X1: works fine with HugeTLB (but no hugetlbfs) and looping git clone, gcc 4.6.4.
V440: fails to boot with 3.16 and gcc 4.9.1 (same message as before, in fault_in_user_windows+0xe0/0x100). Tried latest git with gcc 4.9.1 but it stops after before getting to the previous failure point: [ 77.871887] console [tty0] enabled [ 77.912630] bootconsole [earlyprom0] disabled
T2000: works fine with gcc 4.9.1 and hugetlb, 3.16. Hangs at boot at the same point.
U2: looping git clone fails with 3.16, no hugetlb(!!!), gcc 4.6.4;
E420R: works fine with gcc 4.6.4. 3.16, hugetlb, looping git clone; fails to boot with current git
E220R: works with gcc 4.6.4, no hugetlb, 3.16. Hangs on boot with current git + hugetlb.
Did not test current git more. Will test the patches on top of 3.16 separately to see if/which one of these is the culprit.
