#     Revert "x86/setup: don't remove E820_TYPE_RAM for pfn 0"
#     
#     This reverts commit bde9cfa3afe4324ec251e4af80ebf9b7afaf7afe.
#     
#     Changing the first memory page type from E820_TYPE_RESERVED to
#     E820_TYPE_RAM makes it a part of "System RAM" resource rather than a
#     reserved resource and this in turn causes devmem_is_allowed() to treat
#     is as area that can be accessed but it is filled with zeroes instead of
#     the actual data as previously.
#     
#     The change in /dev/mem output causes lilo to fail as was reported at
#     slakware users forum, and probably other legacy applications will
#     experience similar problems.
