powerpc/mm: fix "section_base" set but not used
The commit 24b6d4164348 ("mm: pass the vmem_altmap to vmemmap_free") removed a line in vmemmap_free(), altmap = to_vmem_altmap((unsigned long) section_base); but left a variable no longer used. arch/powerpc/mm/init_64.c: In function 'vmemmap_free': arch/powerpc/mm/init_64.c:277:16: error: variable 'section_base' set but not used [-Werror=unused-but-set-variable] Signed-off-by: Qian Cai <cai@lca.pw> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
