avr32: Fix out-of-range rcalls in large kernels
Replace handcoded rcall instructions with the call pseudo-instruction. For kernels too far over 1MB the rcall instruction can't reach and linking will fail. We already call the final linker with --relax which converts call pseudo-instructions to the right things anyway. This fixes arch/avr32/kernel/built-in.o: In function `syscall_exit_work': (.ex.text+0x198): relocation truncated to fit: R_AVR32_22H_PCREL against symbol `schedule' defined in .sched.text section in kernel/built-in.o arch/avr32/kernel/built-in.o: In function `fault_exit_work': (.ex.text+0x3b6): relocation truncated to fit: R_AVR32_22H_PCREL against symbol `schedule' defined in .sched.text section in kernel/built-in.o But I'm still left with arch/avr32/kernel/built-in.o:(.fixup+0x2): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+45a arch/avr32/kernel/built-in.o:(.fixup+0x8): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+8ea arch/avr32/kernel/built-in.o:(.fixup+0xe): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+abe arch/avr32/kernel/built-in.o:(.fixup+0x14): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+ac8 arch/avr32/kernel/built-in.o:(.fixup+0x1a): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+ad2 arch/avr32/kernel/built-in.o:(.fixup+0x20): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+adc arch/avr32/kernel/built-in.o:(.fixup+0x26): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+ae6 arch/avr32/kernel/built-in.o:(.fixup+0x2c): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+af0 arch/avr32/kernel/built-in.o:(.fixup+0x32): additional relocation overflows omitted from the output These are caused by a similar problem with 'rjmp' instructions. Unfortunately, there's no easy fix for these at the moment since we don't have a arbitrary-range 'jmp' instruction similar to 'call'.
