Christophe Leroy 9fa9712644 powerpc/vdso: Mark the vDSO code read-only after init
VDSO text is fixed-up during init so it can't be const,
but it can be read-only after init.

Do the same as x86 in commit 018ef8dcf3 ("x86/vdso: Mark the vDSO
code read-only after init") and arm in commit 11bf9b8658 ("ARM/vdso:
Mark the vDSO code read-only after init"), move it into
ro_after_init section.
