[PATCH] efi: add conditional include of asm/early_ioremap.h

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The code in efi.c uses early_memremap(), but relies on a transitive
include rather than including asm/early_ioremap.h directly.
Unfortunately, this header does not exist on ia64, so it cannot be
included directly.

Commit f7d924894265 ("arm64/efi: refactor EFI init and runtime code
for reuse by 32-bit ARM") attempted to work around this by including
asm/efi.h, which transitively includes asm/early_ioremap.h on most
architectures. However, since asm/efi.h does not exist on ia64 either,
this is not much of an improvement.

So instead, just include asm/early_ioremap.h directly, unless CONFIG_IA64
is defined.

Fixes: f7d924894265 ("arm64/efi: refactor EFI init and runtime code for reuse by 32-bit ARM")
