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

[Christophe Leroy]

book3s/32 and 8xx don't use vmalloc for modules.

Print the modules area at startup as part of the virtual memory layout:

[0.00] Kernel virtual memory layout:
[0.00]   * 0xffafc000..0xc000  : fixmap
[0.00]   * 0xc900..0xffafc000  : vmalloc & ioremap
[0.00]   * 0xb000..0xc000  : modules
[0.00] Memory: 118480K/131072K available (7152K kernel code, 2320K 
rwdata, 1328K rodata, 368K init, 854K bss, 12592K reserved, 0K cma-reserved)
