Here, we can see:
+skip:
- if (boot_cpu_data.x86_vendor == X86_VENDOR_AMD)
- goto disable;
Refer to 4.9.81's kaiser.c https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree...
Also 4.4.115's kaiser.c https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree...
So, any hints on what you think should be the correct fix here?
thanks,
