Need to hack kernel module of VTune (remap_page_range)

Need to hack kernel module of VTune (remap_page_range)

[Tetsuji "Maverick" Rai]

I'm trying to install VTune by Intel (see
http://www.intel.com/software/products/vtune/vlin/index.htm for
details) but this creates a kernel module for "older" kernels; it can
be built on my Gentoo w/kernel 2.6.11.12, but it looks for symbol
"remap_page_range" which was used until 2.6.8 or 2.6.9.  So I would
like to know how to hack this kernel module (fortunately sources are
with the package).   What's the key?

It's defined in linux/mm/nommu.c in kernel-2.6.9.

Thanks in advance!!

You may look into this:

"remap_pfn_range()"
	http://lwn.net/Articles/104333/

Conversion to remap_pfn_range() in sound/
	http://linux.bkbits.net:8080/linux-2.6/cset@41768440y2w0JI791mgE2LQjagt5dA

It seems that s/remap_page_range/remap_pfn_range/g and shifting 3-rd argument
when needed is enough.
