[WOLK-devel] [patch] for wolk4.5, grsec/pax - rmap

[<mic...@gm...>]

hi list, 

ive patched the problem myself, because grsec/pax don't have troubles  
without CONFIG_GRKERNSEC_PAX_RANDEXEC. 
ive never run a wolk without all other grsec/pax options except  
CONFIG_GRKERNSEC_PAX_RANDEXEC. 

the patch applies cleanly and the box runs rock solied as wolk4.4s 

ps.:ive allready sent this to marc.
