Get the load-low patch from http://user-mode-linux.sourceforge.net/patches.html It will make UML load where every normal process loads when CONFIG_MODE_SKAS is on and CONFIG_MODE_TT is off. This should get you past valgrind's address space assumptions. As a side-benefit, this will allow UML to have much greater physical memory without needing to go to highmem. If you take advantage of this, either enable CONFIG_STATIC_LINK or keep the physical memory size below about 750M. The reason is you don't want to push UML physical memory into the 0x40000000 area occupied by shared libraries. With CONFIG_STATIC_LINK, this problem goes away and you can have physical memory up to about 2.75G. Let me know if there are any problems. It's not well tested - I ran it enough to see it panic because it had no root filesystem. My current work box doesn't have skas on it yet, so I can't boot this one up totally.
