Dead symbols in CMl1

I think I've identified a number of dead symbols. Here's a list:

CONFIG_BAGETBSM (Baget Backplane Shared Memory support)
Set in arch/mips64/config.in, not used anywhere.

CONFIG_ACPI_INTERPRETER (ACPI interpreter)
Set in arch/ia64/config.in, not used anywhere.

CONFIG_BINFMT_JAVA (Kernel support for JAVA binaries)
Set in arch/parisc/config.in and arch/cris/config.in, not used anywhere.

CONFIG_SCSI_DECSII (DEC SII SCSI Driver)
Set in drivers/scsi/Config.in, not used anywhere.

CONFIG_PROFILE (Enable traffic profiling)
CONFIG_PROFILE_SHIFT (Profile shift count)
Set in arch/cris/config.in, not used anywhere.

CONFIG_SERIAL_21285_OLD (Use /dev/ttyS0 device)
Set in drivers/char/Config.in, not used anywhere

The following patch removes them cleanly:

Hoplophobia (n.): The irrational fear of weapons, correctly described by Freud as "a sign of emotional and sexual immaturity". Hoplophobia, like homophobia, is a displacement symptom; hoplophobes fear their own "forbidden" feelings and urges to commit violence. This would be harmless, except that they project these feelings onto others. The sequelae of this neurosis include irrational and dangerous behaviors such as passing "gun-control" laws and trashing the Constitution. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
