[ARM] 3648/1: Update struct ucontext layout for coprocessor registers
Patch from Daniel Jacobowitz In order for userspace to find saved coprocessor registers, move them from struct rt_sigframe into struct ucontext. Also allow space for glibc's sigset_t, so that userspace and kernelspace can use the same ucontext layout. Define the magic numbers for iWMMXt in the header file for easier reference. Include the size of the coprocessor data in the magic numbers. Also define magic numbers and layout for VFP, not yet saved.
