vmalloc errors in 2.4.20

[sandeep uttamchandani <sm_uttamchandani@yahoo.com>]

The linux kernel 2.4.20 seems to have problems with
vmalloc. Here is what I did:

In my driver, I try to allocate a buffer of size 512K
using vmalloc ( kmalloc cannot allocate more than
128K). It generates a kernel oops message saying that
the virtual memory cannot be allocated.

I suspect there is a problem with the address range
defined for vmalloc namely by VMALLOC_START and
VMALLOC_END. 

Any thoughts of what might be going-on ? 

Please do let me know if you want to look at the
kernel oops message. 

Thanks,
Sandeep
