Message-Id: <1219294018-12557-3-git-send-email-galak@kernel.crashing.org>

Subject: [PATCH 2/9] fs-enet: remove code associated with !CONFIG_PPC_MERGE
Now that arch/ppc is gone we don't need CONFIG_PPC_MERGE anymore remove
the dead code associated with !CONFIG_PPC_MERGE.
With this change the pre_request_irq() and post_free_irq() calls became
nops so they have been removed. Also removed fs_request_irq() and
fs_free_irq() and just called request_irq() and free_irq().
