[PATCH 09/11] ppc: remove ppc_ide_md

Thu Feb 14 11:37:29 EST 2008
* Add special cases for pplus and prep to ide_default_{irq,io_base}()
(+ FIXMEs about the need to use IDE platform host driver instead).
* Remove no longer needed ppc_ide_md and struct ide_machdep_calls.
* Then remove <linux/ide.h> include from:
- arch/powerpc/kernel/setup_32.c
- arch/ppc/kernel/ppc_ksyms.c
- arch/ppc/kernel/setup.c
- arch/ppc/platforms/pplus.c
- arch/ppc/platforms/prep_setup.c
There should be no functional changes caused by this patch.
