[Xen-devel] Question: how to unmap memory mapped with direct_kernel_remap_pfn_range() ?

["Santos, Jose Renato G" <joserenato.santos@xxxxxx>]

Hi,

Xenoprof buffers are mapped into the kernel using
direct_kernel_remap_pfn_range().
I need to unmap the buffer when it is not needed anymore.

However, I could not find any function that unmaps pages previously
mapped with direct_kernel_remap_pfn_range().
Any suggestion on how to do this?

Thanks

Renato
