RE: [Xen-devel] [PATCH] [XENOPROF] fix shared_xenoprof_page_with_guest() and clean up

["Woller, Thomas" <thomas.woller@xxxxxxx>]

Isaku,
When xenoprof is enabled in the 64bit linux dom0, then during the build,
the xenoprof.h include file is not found, and dom0 fails to build with
an error.
It looks like there is no soft link to the i386 version created, but I
am not sure of all of your cleanup modifications and how the build
should actually occur using the i386 xenoprof.h file for x86_64 build. 
Can you provide fix? 
Thanks,
Tom
