Please include this patch in the ne= xt um patches if nobody objects. This patch is again 2.4.22 but should work with any 2.4.* kernel. ----- --- linux-2.4.22-uml/Documentation/Configure.help Wed Sep 17 12:03:54= 2003 +++ linux-2.4.22-uml2/Documentation/Configure.help Mon Sep 29 21:00:38= 2003 @@ -27646,6 +27646,98 @@ CONFIG_CRYPTO_TEST Quick & dirty crypto test module. +Separate Kernel Address Space support +CONFIG_MODE_SKAS + This option controls whether skas (separate kernel address space) + support is compiled in.
