Hi,

[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url:    https://github.com/0day-ci/linux/commits/Suravee-Suthikulpanit/iommu-AMD-Introduce-IOMMU-AVIC-support/20160714-021233
base:   https://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git next
config: x86_64-randconfig-s1-07192221 (attached as .config)
compiler: gcc-4.4 (Debian 4.4.7-8) 4.4.7
reproduce:
         # save the attached .config to linux build tree
         make ARCH=x86_64 

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text+0x7a65ef): Section mismatch in reference from the function iommu_init_ga_log() to the function .init.text:free_ga_log()
    The function iommu_init_ga_log() references
    the function __init free_ga_log().
    This is often because iommu_init_ga_log lacks a __init
    annotation or the annotation of free_ga_log is wrong.
