Only 5 undocumented configuration symbols left

Only 5 undocumented configuration symbols left

[Eric S. Raymond]

The current list of symbols with missing help is very short. Here it is:

PPC port:

CONFIG_BLK_DEV_MPC8xx_IDE
CONFIG_IRQ_ALL_CPUS
CONFIG_USE_MDIO

CRIS port:

CONFIG_ETRAX_FLASH_BUSWIDTH
CONFIG_ETRAX_I2C_USES_PB_NOT_PB_I2C

Let's finish this off, people!

Since I don't actually know what you're talking about, I'll just make picky
little comments about the grammar, etc. ;)

This is usually "say Y here." Minor, I know, but it'd be nice to get the
nomenclature standardized.

(Actually, "...to be selected in order to use some drivers, such as the DS1302
realtime clock driver, that access the I2C I/O pins directly instead of going
through the I2C driver." might scan better.)

This option gives the kernel permission to distribute IRQs across multiple CPUs.
Saying N here will route all IRQs to the first CPU. Generally SMP PowerMacs can
answer Y. SMP IBM CHRP boxes or Power3 boxes should say N for now.
