Please validate test kernel on UltraSPARC machines

Hello,

recently, a kernel patch series was posted to fix issues with HugeTLB
on UltraSPARC (sun4u) machines [1]. I have built a test Debian kernel 
which includes the patch and uploaded it to [2].

Could someone test this kernel and report back whether it causes any
regressions and also whether it possible fixes the stability issues
we're seeing on UltraSPARC machines with newer kernels?

Thanks,
Adrian
