Subject: user virtual address to physical address

Hi,

I need to convert a user virtual address to its
corresponding physical address.
I know that if the virtual address is from kernel,
we could use virt_to_phys.
Is there a similar helper function
to convert user virtual address.?

Thanks,
Fredrick
