Michael Karcher faeaa3bc9f Mitigation for "clone on sparc might fail with -EFAULT for no valid reason" (bz 31394) ... It seems the kernel can not deal with uncommitted stack space in the area intended for the register window when executing the clone() system call. So create a nested frame (proxy for the kernel frame) and flush it from the processor to memory to force committing pages to the stack before invoking the system call.
