[PATCH] Make number of IDE interfaces configurable
Make IDE_HWIFS configurable if EMBEDDED This lets us lop as much as 16k off an x86 build. It's a little ugly, but it's dead simple. Note the fix for HWIFS < 2. Sizing interfaces dynamically unfortunately turns out to be pretty major surgery. add/remove: 0/1 grow/shrink: 0/11 up/down: 0/-16182 (-16182) function old new delta ide_hwifs 16920 1692 -15228 init_irq 1113 750 -363 ideprobe_init 283 138 -145 ide_pci_setup_ports 1329 1193 -136 save_match 85 - -85 ide_register_hw_with_fixup 367 287 -80 ide_setup 1364 1308 -56 is_chipset_set 40 4 -36 create_proc_ide_interfaces 225 205 -20 init_ide_data 84 67 -17 ide_probe_for_cmd640x 1198 1183 -15 ide_unregister 1452 1451 -1 Signed-off-by: Matt Mackall <mpm@selenic.com> Cc: Bartlomiej Zolnierkiewicz <B.Zolnierkiewicz@elka.pw.edu.pl> Acked-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
