parisc: Allow live-patching of __meminit functions
When making the text sections writeable with set_kernel_text_rw(1), include all text sections including those in the __init section. Otherwise functions marked with __meminit will stay read-only. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org> # 4.20+
