Hi,

since 2.6.29-rcX it seems to be not allowed anymore to use
remap_pfn_range() to remap physical RAM to userland. This restriction
applies only if CONFIG_X86_PAT is enabled. It seems that vm_insert_page()
does not have this restriction. Am I correct? And what is the reason
for this restriction?

Kind regards,
