With the release of LLVM 3.3 clang is now able to compile the Linux kernel with a number of small patches (available from the LLVMLinux git repo). Use the frame pointer to calculate the start of the stack for current_thread_info() The existing code uses the stack pointer to do this calculation. Using the frame pointer yeilds the same value in a portable way. This change supports being able to compile the kernel with gcc and Clang.
