    SubjectIDE/SUPPORT_VLB_SYNC in 2.5.x

    SUPPORT_VLB_SYNC is now unconditionally hardcoded to 1 in
    drivers/ide/ide-taskfile.c.

    While most architectures disable it, which no longer works:

    | tux$ find include -type f | xargs grep SUPPORT_VLB_SYNC
    | include/asm-cris/ide.h:#undef SUPPORT_VLB_SYNC
    | include/asm-cris/ide.h:#define SUPPORT_VLB_SYNC 0
    | include/asm-m68k/ide.h:#undef SUPPORT_VLB_SYNC
    | include/asm-m68k/ide.h:#define SUPPORT_VLB_SYNC 0
    | include/asm-mips/ide.h:#undef SUPPORT_VLB_SYNC
    | include/asm-mips/ide.h:#define SUPPORT_VLB_SYNC 0
    | include/asm-ppc/ide.h:#undef SUPPORT_VLB_SYNC
    | include/asm-ppc/ide.h:#define SUPPORT_VLB_SYNC 0
    | include/asm-sparc/ide.h:#undef SUPPORT_VLB_SYNC
    | include/asm-sparc/ide.h:#define SUPPORT_VLB_SYNC 0
    | include/asm-sparc64/ide.h:#undef SUPPORT_VLB_SYNC
    | include/asm-sparc64/ide.h:#define SUPPORT_VLB_SYNC 0
    | include/linux/ide.h:#ifndef SUPPORT_VLB_SYNC /* 1 to support weird 32-bit chips */
    | include/linux/ide.h:#define SUPPORT_VLB_SYNC 1 /* 0 to reduce kernel size */

    Wouldn't it be better to enable it on architectures which can have a VESA local
    bus (ia32 only?) only?

    In personal conversations with technical people, I call myself a hacker. But
    when I'm talking to journalists I just say "programmer" or something like that.
