What is happening with these patches? What about the 4.4-stable backport as well? Does anyone care about these anymore? Do we have any product customers using 32-bit Cortex CPUs anymore? David - FYI - everything in my Spectre branch is now in mainline as of 4.20-rc3, and I have nothing further planned for core 32-bit ARM Spectre workarounds.
