Retpoline patch seems to have messed up kernel config
The retpoline patch has been backported to the 4.14.* kernel, starting at 4.14.82. The problem is, when doing the "make menuconfig", retpoline can be disabled but SMT is forced on.
This is in "Processor type and features", you will see in there: Code:
Processor type and features I am wondering if this issue is showing up in later kernels? Further info at blog post: http://bkhome.org/news/201812/kernel...-compiled.html |
Why don't you grok the patch ported, (forward and back) and read the thread and inform yourself? I've had to do that occasionally. Linus doesn't bite anymore, I'm told. The DFL is gone and the BDFL is back :)

I have recently faced a similar issue when trying to build old code against kernel 4.19.6, in my case CONFIG_TRACEPOINTS was disabled and hidden... The fix is easy though. Edit init/Kconfig, find the line where your target is, and add a description after it. For example:
Code:
config CONFIG_SCHED_SMT Code:
config CONFIG_SCHED_SMT |
