[PATCH 3/9] powerpc/mm: Remove extern from function definition

[Breno Leitao <leitao@debian.org>]

Function huge_ptep_set_access_flags() has the 'extern' keyword in the
function definition and also in the function declaration. This causes a
warning in 'sparse' since the 'extern' storage class should be used only on
symbol declarations.

	arch/powerpc/mm/pgtable.c:232:12: warning: function 'huge_ptep_set_access_flags' with external linkage has definition

This patch removes the keyword from the definition part, while keeps it in
the declaration part.
