I thought SCTP changes were backed out just because of these 'make oldconfig'
errors from the 2.4 tree.

Anyway, i have submitted the attached patch that should fix this to davem.
'make oldconfig' and 'make menuconfig' worked fine after applying this patch.

However i am having problem with 'make xconfig'. When CONFIG_SCTP_HMAC_MD5
or CONFIG_SCTP_HMAC_SHA1 is enabled, everything under Crptographic options
is greyed out.

I would appreciate if some config expert can take a look at this and figure
out what is happening.

Thanks
Sridhar
