[PATCH] Configure.help: Bad URL for CONFIG_SYN_COOKIES

[PATCH] Configure.help: Bad URL for CONFIG_SYN_COOKIES

[Robert Love]

The provided URL for more information re SYN Cookies is bad.  I
originally posted a patch to fix this in the 2.4-pre series but it was
not merged.  I am reposting because I was in need of the URL and again
got stuck on the stale URL in Configure.help.

This is against Configure.help 2.41, as in 2.4.8-ac7.

OK, Steve and Alan, I've uploaded this to the CML2 page as 2.42.

...Virtually never are murderers the ordinary, law-abiding people
against whom gun bans are aimed.  Almost without exception, murderers
are extreme aberrants with lifelong histories of crime, substance
abuse, psychopathology, mental retardation and/or irrational violence
against those around them, as well as other hazardous behavior, e.g.,
automobile and gun accidents."

[PATCH] let Net Devices feed Entropy, updated (2/2)

[Robert Love]

part 2 of 2, against 2.4.8-ac7. see previous email for more information.

this patch enables the 3c501, 3c505, 3c509, 3c523, 3c59x, 8139too,
cs89x0, eepro, eepro100, eexpress, ibmlana, ne2k-pci, pcnet_cs,
xircom_tulic_cb, sk_mca, smc9194, tulic_core, and wavelan drivers to use
the new flag. all of the drivers which previously contributed entropy
are listed above. *None of these drivers will contribute unless you
enable the configuration setting*
