CONFIG_PPP_MPPE can be enabled without CONFIG_CRYPTO.
This results in this warning when running make modules_install:
if [ -r System.map -a -x /sbin/depmod ]; then /sbin/depmod -ae -F
System.map 2.6.12-rc4-mm2=LoulousMobile; fi
WARNING:
/lib/modules/2.6.12-rc4-mm2=LoulousMobile/kernel/drivers/net/ppp_mppe.ko
needs unknown symbol crypto_alloc_tfm
WARNING:
/lib/modules/2.6.12-rc4-mm2=LoulousMobile/kernel/drivers/net/ppp_mppe.ko
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.
