[kernel-hardening] [PATCH] powerpc: Increase ELF_ET_DYN_BASE to 1TB for 64-bit applications

[Daniel Micay]

Rather than doing this, the base should just be split for an ELF
interpreter like PaX. It makes sense for a standalone executable to be
as low in the address space as possible. Doing that ASAP fixes issues
like this and opens up the possibility of fixing stack mapping ASLR
entropy on various architectures. It should be a pretty small change.
