On a 4.18-rc1 kernel the following warning is seen on i.MX51 and i.MX53:

CPU0: Spectre v2: firmware did not set auxiliary control register IBE bit, system vulnerable

Select the ARM_CORTEX_A8_CVE_2017_5715 workaround for i.MX51/i.MX53 to fix the problem.

With this patch applied the kernel reports:

CPU0: Spectre v2: using BPIALL workaround

This depends on Nishanth Menon's series that introduces the ARM_CORTEX_A8_CVE_2017_5715 Spectre workaround.

I saw that Tom has just applied Nishanth Menon's series.

Can this one also be applied for 2018.07?

Thanks
