As discussed with Tomasz on irc: The sad thing here is that for this
array only 8 bytes are freed when .init.rodata is thrown away (that is
two pointers). The actual data---5 + 8 bytes + maybe aligning---isn't
freed though.

We wondered if there is a nice and easy way to throw away the
characters, too.

The only way I currently see is:

	const char xxti[] __initconst = "xxti";
	...

	static const char *fin_pll_p[] __initdata = {
		xxti,
		...
	};

but this definitively doesn't qualify as "nice and easy". Is there an
alternative?

Best regards
Uwe
