Description Dean Nelson 2011-01-26 15:20:58 UTC 
Since the recent setting of CONFIG_DEBUG_SECTION_MISMATCH to 'y', builds of RHEL6.1 are seeing the following warning message:

  WARNING: mm/built-in.o(.text+0x405c0): Section mismatch in reference from the function hugetlb_register_node() to the function .init.text:hugetlb_sysfs_add_hstate()
  The function hugetlb_register_node() references
  the function __init hugetlb_sysfs_add_hstate().
  This is often because hugetlb_register_node lacks a __init
  annotation or the annotation of hugetlb_sysfs_add_hstate is wrong.

It turns out that the annotation of hugetlb_sysfs_add_hstate() is wrong. And can be corrected by backporting the following linux-2.6 commit:
