Michael Ellerman 0b0e9b5adc powerpc/vmlinux.lds: Add an explicit symbol for the SRWX boundary
[ Upstream commit b150a4d12b919baf956b807aa305cf78df03d0fe ]

Currently __init_begin is used as the boundary for strict RWX between
executable/read-only text and data, and non-executable (after boot) code
and data.

But that's a little subtle, so add an explicit symbol to document that
the SRWX boundary lies there, and add a comment making it clear that
__init_begin must also begin there.
