Vmalloc Information Needed

For a user/kernel configuration of 3/1GB and (0-16M DMA , 16-896 - Low ,
896 - 1024 - High )
*Q:* Is amount of memory allocated to Vmalloc limited to 128MB?

I read an article which said to increase the Vmalloc allocation size we
need to either
*1)* Change user/kernel distribution like 2.75/1.25 which proportionately
increase the address space available to High memory
*2)* For a fixed user/kernel distribution reduce the low memory like 16-800
thereby increasing the size available for high memory.

In either of the case the memory for vmalloc is limited to user/kernel
distribution . i.e. the amount of virtual address space available in high
memory.

I am a beginner, so please let me know if my understanding is correct..and
rectify in-case of wrong.?

Thanks,
Anup Buchke.
