powerpc/32: Display modules range in virtual memory layout
book3s/32 and 8xx don't use vmalloc for modules. Print the modules area at startup as part of the virtual memory layout: [ 0.000000] Kernel virtual memory layout: [ 0.000000] * 0xffafc000..0xffffc000 : fixmap [ 0.000000] * 0xc9000000..0xffafc000 : vmalloc & ioremap [ 0.000000] * 0xb0000000..0xc0000000 : modules [ 0.000000] Memory: 118480K/131072K available (7152K kernel code, 2320K rwdata, 1328K rodata, 368K init, 854K bss, 12592K reserved, 0K cma-reserved) Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/98394503e92d6fd6d8f657e0b263b32f21cf2790.1623438478.git.christophe.leroy@csgroup.eu
