Subject[ 103/149] iommu/amd: Fix section warning for prealloc_protection_domains
3.2-stable review patch.  If anyone has any objections, please let me know.


From: Steffen Persvold <>

commit cebd5fa4d3046d5b43ce1836a0120612822a7fb0 upstream.

Fix the following section warning in drivers/iommu/amd_iommu.c :

WARNING: vmlinux.o(.text+0x526e77): Section mismatch in reference from the function prealloc_protection_domains() to the function .init.text:alloc_passthrough_domain()
The function prealloc_protection_domains() references
the function __init alloc_passthrough_domain().
This is often because prealloc_protection_domains lacks a __init
annotation or the annotation of alloc_passthrough_domain is wrong.
