WebThe early ioremap interfaces are intended for situations where boot code needs to make temporary virtual mappings before the normal ioremap interfaces are available. Typically, this means before paging_init() has run. These patches are layered on top of generic fixmap patches which were discussed here ... WebAug 29, 2009 · I too get this warning message.

WebThe early mapping of the EFI memory map is unmapped during an early: initcall, at which time the early ioremap support is long gone. Fix by adding the missing call to early_ioremap_reset to: setup_arch (), and move the offending early_memunmap to right after: the point where the early mapping of the EFI memory map is last used.
