    SubjectRe: SiI3112 Serial ATA Maxtor 6Y120M0 incorrect geometry detected

    This was discussed to death on lkml.

    To make long story short:
    - BIOS CHS is _useless_ for IDE driver
    - IDE driver returns different geometry for 2.[2,4,6].x kernels
    - Andries removed ide-geometry.c in 2.5 but didn't HDIO_GETGEO ioctl
    - BIOS CHS is available through EDD driver now
    - this is a parted problem

    I'm tired of this issue and this is what I'm going to do:
    - remove CHS info from IDE printks and /proc/ide/
    - add BLKGETSTART ioctl for getting partition's start sector
    (this is the only legitimate use of HDIO_GETGEO currently)
    - at least obsolete HDIO_GETGEO in IDE or even remove it (failing is
    better than returning unexpected results)
    - silence complainers :)
