Subject[PATCH] powerpc/32: Display modules range in virtual memory layout
Date
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)
