ARMv7-A: Modify up_fullcontextrestore() for CONFIG_BUILD_KERNEL. It changed CPSR while in kernel. That will crash is the new CPSR is user mode while executing in kernel space. Fixed by adding a SYS_context_restore system call. There is an alternative, simpler modification to up_fullcontextrestore() that could have been done: It might have been possible to use the SPSR instead of the CPRSR and then do an exception return from up_fullcontextrestore(). That would be more efficient, but I never tried it.
