Subject: lib/genalloc.c: use vzalloc_node() to allocate the bitmap
Some devices may have big memory on chip, such as over 1G. In some cases,
the nbytes maybe bigger then 4M which is the bounday of the memory buddy
system (4K default).
So use vzalloc_node() to allocate the bitmap. Also use vfree to free it.
