[34-longterm 071/260] binfmt_misc: fix binfmt_misc priority

[Paul Gortmaker]

From: Jan Sembera <jsembera@xxxxxxx>

commit ee3aebdd8f5f8eac41c25c80ceee3d728f920f3b upstream.

Commit 74641f584da ("alpha: binfmt_aout fix") (May 2009) introduced a
regression - binfmt_misc is now consulted after binfmt_elf, which will
unfortunately break ia32el.  ia32 ELF binaries on ia64 used to be matched
using binfmt_misc and executed using wrapper.  As 32bit binaries are now
matched by binfmt_elf before bindmt_misc kicks in, the wrapper is ignored.

The fix increases precedence of binfmt_misc to the original state.
