Don't populate the read-only u8 array buf on the stack at run time but
instead make it static const; makes object code smaller saving over 480
bytes:

H A Denlighten.cdiff 99158f10 Tue May 24 16:48:38 MDT 2016 Andy Lutomirski <luto@kernel.org> x86/xen: Simplify set_aliased_prot()

A year ago, via the following commit:

aa1acff356bb ("x86/xen: Probe target addresses in set_aliased_prot() before the hypercall")

I added an explicit probe to work around a hypercall issue. The code can
be simplified by using probe_kernel_read().

No change in functionality.
