[PASEMI] Nemo board doesn't boot anymore after the commit "powerpc/book3s64/pkeys: Simplify pkey disable branch"

[Christian Zigotzky]

Hello,

The Nemo board (A-EON AmigaOne X1000) [1] doesn't start with the latest 
Git kernel anymore after the commit "powerpc/book3s64/pkeys: Simplify 
pkey disable branch" [2].

I bisected today [3].

Result: powerpc/book3s64/pkeys: Simplify pkey disable branch 
(a4678d4b477c3d2901f101986ca01406f3b7eaea) [2] is the first bad commit.

Unfortunately I wasn't able to revert the first bad commit. The first 
bad commit depends on many other commits, which unfortunately I don't 
know. I tried to remove the modifications of the files from the first 
bad commit but without any success. There are just too many dependencies.

Additionally I reverted the commit "selftests/powerpc: Fix pkey syscall 
redefinitions" [4] and compiled a new kernel but without any success.

Could you please check the first bad commit?

Thanks,
Christian
