Impact: obsolete feature removal The zImage kernel format has been functionally unused for a very long time. It is just barely possible to build a modern kernel that still fits within the zImage size limit, but it is highly unlikely that anyone ever uses it. Furthermore, although it is still supported by most bootloaders, it has been at best poorly tested (or not tested at all); some bootloaders are even known to not support zImage at all and not having even noticed. Also remove some really obsolete constants that no longer have any meaning. LKML-Reference: <49B703D4.1000008@zytor.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
