[uml-devel] about skas

[李慧霸]

Hello, I'm new to UML, and I'm very interested in the idea that address space 
be created and manipulated (skas).
So, is there any detailed material on that idea? 
Or, could you give me some guidance for reading the source code?

Thanks!

[uml-devel] [PATCH] Keep UML Kconfig in sync with x86

[Jeff Dike]

Fix a 2.6.24-rc3 UML build breakage introduced by commit
1032c0ba9da5c5b53173ad2dcf8b2a2da78f8b17 - it introduces X86_32, with
many things which UML needs depending on it.

This patch adds definitions of X86_32 and RWSEM_XCHGADD_ALGORITHM to
the UML/i386 Kconfig.
