Hi all,

Commit d6c763afab14 "arm64/mm: Remove hack in mmap randomize layout" fixes a 
security issue which reduces the entropy for mmap base address by half [1]. 
A attempt to guess where the stack is mapped via brute-force needs just half 
the attempts.

I found this patch was added to v3.19-rc1 but should be added as well to:
v3.18, v3.14, v3.12 and v3.10

Best regards,
Matthias Brugger
