Subject: [BUG 2.6.36-rc5] of_i2c.ko <-> i2c-core.ko dependency loop

Running modules_install from a newly built 2.6.36-rc5 kernel
on my 32-bit PowerMac results in:

WARNING: Module /lib/modules/2.6.36-rc5/kernel/drivers/i2c/busses/i2c-powermac.ko ignored, due to loop
WARNING: Loop detected: /lib/modules/2.6.36-rc5/kernel/drivers/i2c/i2c-core.ko needs of_i2c.ko which needs i2c-core.ko again!
WARNING: Module /lib/modules/2.6.36-rc5/kernel/drivers/i2c/i2c-core.ko ignored, due to loop

WARNING: Module /lib/modules/2.6.36-rc5/kernel/sound/ppc/snd-powermac.ko ignored, due to loop

> grep '.*I2C.*=' .config
CONFIG_OF_I2C=m
CONFIG_I2C=m
CONFIG_I2C_BOARDINFO=y
CONFIG_I2C_CHARDEV=m
CONFIG_I2C_POWERMAC=m

I can't say exactly when this started, haven't built kernels on this
box in a while.
