Additionally, callers of the function must check against that value. early_reserve_e820() should be prepared for the region found to be outside of the addressable range on 32-bits. e820_update_range_map() should not blindly update e820, but should do all it work on the map it got a pointer passed for (which in 50% of the cases is &e820_saved). It must also not call e820_add_region(), as that again acts on e820 unconditionally. The issues were found when trying to make this option work in our Xen kernel (i.e. where some of the silent assumptions made in the code would not hold).

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>

This causes the linker to not report an error when __this_fixmap_does_not_exist() is called with a non-constant parameter. Ingo defined __this_fixmap_does_not_exist() because he wanted to get virt addresses of fix memory of nest level by non-constant index. But we can fix this and still keep the link-time check: We can get the four slot virt addresses on link time and store them to array slot_virt[]. Then we can then refer the slot_virt with non-constant index, in the ioremap-leak detection code.
