Hi Andrew,

CONFIG_PPP_MPPE can be enabled without CONFIG_CRYPTO.
This results in this warning when running make modules_install:
if [ -r -a -x /sbin/depmod ]; then /sbin/depmod -ae -F 2.6.12-rc4-mm2=LoulousMobile; fi
needs unknown symbol crypto_alloc_tfm
needs unknown symbol crypto_free_tfm

By the way, looking at drivers/net/ppp_mppe.c, it looks like sha1 and
arc4 are needed at runtime.

The attached patch selects all these when PPP_MPPE is selected.
