Instead of stashing the value of the link register in x28 before setting up the stack and calling into C code, create an ordinary PCS compatible stack frame so that we can push the return address onto the stack. Since exception handlers require a stack as well, assign the stack pointer register before installing the vector table. Note that this accounts for the difference between THREAD_START_SP and THREAD_SIZE, given that the stack pointer is always decremented before calling into any C code.
