kernel 2.6.11.5 compile errors (fwd)

[Rolando Abarca <rabarca@dcc.uchile.cl>]

I was trying to compile kernel 2.6.11.5 and got this error:

drivers/ide/ppc/pmac.c: In function `pmac_ide_build_dmatable':
drivers/ide/ppc/pmac.c:1583: warning: implicit declaration of function 
`ide_build_sglist'
drivers/ide/ppc/pmac.c: In function `pmac_ide_setup_dma':
drivers/ide/ppc/pmac.c:2016: error: `__ide_dma_off_quietly' undeclared (first 
use in this function)
drivers/ide/ppc/pmac.c:2016: error: (Each undeclared identifier is reported 
only once
drivers/ide/ppc/pmac.c:2016: error: for each function it appears in.)
drivers/ide/ppc/pmac.c:2017: error: `__ide_dma_on' undeclared (first use in 
this function)
drivers/ide/ppc/pmac.c:2026: error: `__ide_dma_timeout' undeclared (first use 
in this function)

any idea why?
thanks a lot.
