[PATCH 00/10] powerpc: Remove use of CONFIG_PPC_MERGE

[Kumar Gala]

This set of patches remove Kconfig and code related to CONFIG_PPC_MERGE
and !CONFIG_PPC_MERGE.  There is some discussion about that one last
use of !PPC_MERGE with respect to the 4xx MTD_NAND_NDFC driver.

Paul, is this something you'd be willing to entertain for 2.6.27?

[PATCH 01/10] powerpc: Remove use of CONFIG_PPC_MERGE

[Kumar Gala]

Now that arch/ppc is gone we don't need CONFIG_PPC_MERGE anymore remove
the dead code associated with !CONFIG_PPC_MERGE out of arch/powerpc
and include/asm-powerpc.

[PATCH 03/10] fs-enet: remove code associated with !CONFIG_PPC_MERGE

[Kumar Gala]

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.
