ARC Linux (not supporting native unaligned access) was failing to boot because __start_kprobe_blacklist was not aligned. This was because per generated vmlinux.lds it was emitted right next to .rodata with strings etc hence could be randomly unaligned. Fix that by ensuring a word alignment. While 4 would suffice for 32bit arches and problem at hand, it is probably better to put 8. | Path: (null) CPU: 0 PID: 1 Comm: swapper Not tainted | 3.15.0-rc3-next-20140430 #2 | task: 8f044000 ti: 8f01e000 task.ti: 8f01e000 | | [ECR ]: 0x00230400 => Misaligned r/w from 0x800fb0d3 | [EFA ]: 0x800fb0d3 | [BLINK ]: do_one_initcall+0x86/0x1bc | [ERET ]: init_kprobes+0x52/0x120 Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: <torvalds@linux-foundation.org> Cc: <rusty@rustcorp.com.au> Cc: <rdunlap@infradead.org> Cc: <jeremy@goop.org> Cc: <arnd@arndb.de> Cc: <dl9pf@gmx.de> Cc: <sparse@chrisli.org> Cc: <anil.s.keshavamurthy@intel.com> Cc: <davem@davemloft.net> Cc: <ananth@in.ibm.com> Cc: <masami.hiramatsu.pt@hitachi.com> Cc: <chrisw@sous-sol.org> Cc: <akataria@vmware.com> Cc: anton Kolesov <Anton.Kolesov@synopsys.com> Link: http://lkml.kernel.org/r/5361DB14.7010406@synopsys.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
