Qoriq P5020 PowerPC board doesn't boot with the latest git version anymore

[Christian Zigotzky]

Hi All,

I compiled the latest git kernel today. Unfortunately my Varisys Cyrus 
Plus board still doesn't boot with the latest git kernel.

After that I patched the kernel source code with the spinlock patch and 
compiled the kernel again. With the spinlock patch, the latest git 
kernel boots without any problems.

Please find attached the spinlock patch.

Cheers,
Christian
