Problems w/ CONFIG_BLK_DEV_MPC8xx_IDE

Hi there,

I just noticed that the vanilla 2.4.22 does not compile with
CONFIG_BLK_DEV_MPC8xx_IDE:

drivers/ide/idedriver.o: In function `ide_timer_expiry':
drivers/ide/idedriver.o(.text+0xaa30): undefined reference to `ide_ack_intr'
drivers/ide/idedriver.o(.text+0xaa30): relocation truncated to fit: R_PPC_REL24

It's the same for the BK trees.

The attached patch fixes that.

Please apply and forward it.

Thanks a million,

Steven
