Ville Juven 686b990a85 arch/ARCH_KERNEL_STACK: Fix signal handling with kernel stack 
There were two issues with signal handling:
- With a kernel stack the "info" parameter was passed from kernel memory.
  This is fixed by making a stack frame to the user stack and copying it
  there.
- If the signal handler uses a system call, the kernel stack was completely
  and unconditionally destroyed, resulting in a crash in the user application

There is also no need to check ustkptr, it is always NULL. Why ? Because
signal delivery is deferred when a system call is being executed.
