[PATCH] powerpc: Fix "attempt to move .org backwards" error
From: Mahesh Salgaonkar With recent machine check patch series changes, The exception vectors starting from 0x4300 are now overflowing with allyesconfig. Fix that by moving machine_check_common and machine_check_handle_early code out of that region to make enough room for exception vector area.
