>
> From: Joerg Roedel <jroe...@suse.de>
>
> A recent commit introduced this section mismatch warning:
>
> WARNING: modpost: vmlinux.o(.text.unlikely+0x22a1f): Section
> mismatch in reference from the function detect_ivrs() to the variable
> .init.data:amd_iommu_force_enable
>
> The reason is that detect_ivrs() is not marked __init while it should be,
> because it is only called from another __init function. Mark
> detect_ivrs() __init to get rid of the warning.

> Fixes: b1e650db2cc4 ("iommu/amd: Add amd_iommu=force_enable
> option")
