Subject: [PATCH] drivers/pci: fix section mismatch warnings in intel-iommu.c

From: Leonardo Potenza <lpotenza@...ind.it>

The functions si_domain_init() and iommu_prepare_static_identity_mapping() have been marked __init, in order to address the following section mismatch messages:

WARNING: drivers/pci/built-in.o(.text+0x3c4e5): Section mismatch in reference from the function si_domain_init() to the function .init.text:si_domain_work_fn()
The function si_domain_init() references
the function __init si_domain_work_fn().
This is often because si_domain_init lacks a __init 
annotation or the annotation of si_domain_work_fn is wrong.

WARNING: drivers/built-in.o(.text+0x415a5): Section mismatch in reference from the function si_domain_init() to the function .init.text:si_domain_work_fn()
The function si_domain_init() references
the function __init si_domain_work_fn().
This is often because si_domain_init lacks a __init 
annotation or the annotation of si_domain_work_fn is wrong.
