Subject: Revert "module: remove the SHF_ALLOC flag on the __versions section."
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=2e45e77787c9d0720b046eb69856edf43b17e33e;p=linux-2.6-omap-h63xx.git

Revert "module: remove the SHF_ALLOC flag on the __versions section."

This reverts commit 9cb610d8e35fe3ec95a2fe2030b02f85aeea83c1.

This was an impressively stupid patch.  Firstly, we reset the SHF_ALLOC
flag lower down in the same function, so the patch was useless.  Even
better, find_sec() ignores sections with SHF_ALLOC not set, so
it breaks CONFIG_MODVERSIONS=y with CONFIG_MODULE_FORCE_LOAD=n, which
refuses to load the module since it can't find the __versions section.
