I need to allocate more than page worth of memory in
kernel. Some documentation that I looked at indicated
I should be using vmalloc() , so I tried using it for
PPC kernel and it couldn't find this symbol. Looked
through the code ( 2.4.4 ) and I didn't see it.
What is the best way to allocate "fairly" large memory
pool for use within the kernel by the driver?

I've written a resident driver which calls vmalloc.
If you're writing a module which calls vmalloc you'll need to make sure EXPORT_SYMBOL(vmalloc)
appears in
linux/arch/$(ARCH)/kernel/$(ARCH)_ksyms.c:
... otherwise insmod will fail.
