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

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?

Subject: [PATCH 01/10] powerpc: Remove use of 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 out of arch/powerpc
and include/asm-powerpc.

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.

Now that arch/ppc is dead CONFIG_PPC_MERGE is always defined for all

CONFIG_PPC instead.

Subject: [PATCH 09/10] pata_sil680: convert CONFIG_PPC_MERGE to CONFIG_PPC

Now that arch/ppc is dead CONFIG_PPC_MERGE is always defined for all
powerpc platforms and we want to get rid of CONFIG_PPC_MERGE use
CONFIG_PPC instead.

This makes "fep" an unused variable. Eliminate this function entirely,
and call request_irq directly from the caller.

Yes, since it's just dead code removal.
