# By default we use remap_pfn_range() kernel API to make kernel pages

# are not accessible to the debugger (see #3214).
# This code enables experimental support
# for vm_insert_page() kernel API, allowing to export kernel pages
# to the userland in more debugger-friendly way. Due to stability
# concerns, not enabled by default yet.
