Adding configs based of Fedora-ARK default config from 6.12.15. We are modifying these with the following configs where available CONFIG_MODIFY_LDT_SYSCALL=n CONFIG_LEGACY_VSYSCALL_NONE=n These options are for old software support which adds performance overhead and potential attack surfaces with go against the CIQ LT kernels priority of performance and security. CONFIG_LIVEPATCH=n We do not have Live patching on for any road-map, is not even supported as a config for ARM. CONFIG_WQ_POWER_EFFICIENT_DEFAULT=y This should be enabled, it often improves performance funnily enough CONFIG_PREEMPT_VOLUNTARY=y CONFIG_HZ=100 These are set to increase throughput CONFIG_PREEMPT_VOLUNTARY=y (default Fedora config) but CONFIG_HZ=100 for higher throughput over the x86_64 default of CONFIG_HZ=1000 which provides lower latency.

This is just the initialization of the configs based on @kerneltoast recommendations and taking the
kernel-ark/rhel-6.12.15kernel configs as a base. We will continue making our own modifications as we sync with futurelinux-6.12.yolddefconfig.Configs Commit
x86_64 built and ran kselftests without blowing up locally, I messed up and didn't collect them into a file so they are actively rerunning.
