Fabio Estevam 1f49856bb0 ARM: 7789/1: Do not run dummy_flush_tlb_a15_erratum() on non-Cortex-A15 ... Commit 93dc688 (ARM: 7684/1: errata: Workaround for Cortex-A15 erratum 798181 (TLBI/DSB operations)) causes the following undefined instruction error on a mx53 (Cortex-A8): Internal error: Oops - undefined instruction: 0 [#1] SMP ARM CPU: 0 PID: 275 Comm: modprobe Not tainted 3.11.0-rc2-next-20130722-00009-g9b0f371 #881 task: df46cc00 ti: df48e000 task.ti: df48e000 PC is at check_and_switch_context+0x17c/0x4d0 LR is at check_and_switch_context+0xdc/0x4d0 This problem happens because check_and_switch_context() calls dummy_flush_tlb_a15_erratum() without checking if we are really running on a Cortex-A15 or not. To avoid this issue, only call dummy_flush_tlb_a15_erratum() inside check_and_switch_context() if erratum_a15_798181() returns true, which means that we are really running on a Cortex-A15.
