ENGR00277201-1 3.10 kernel panic when running gpu stress test
The kernel panic is caused by gcc 4.8.1 build logic.
8044b000: e24bd010 sub sp, fp, #16
8044b004: e1500004 cmp r0, r4
8044b008: b1a00004 movlt r0, r4
8044b00c: a51b0018 ldrge r0, [fp, #-24]
8044b010: e89da810 ldm sp, {r4, fp, sp, pc}
With this logic, r0 may return 0xffffffff randomly in Cortex A9 processor.
Current workaround is enable ARM_UNWIND to avoid such disassemble logic.
