TurboSched is a new Linux kernel scheduler that's been in development by IBM for maximizing use of turbo frequencies for the longest possible periods of time. Rather than this scheduler trying to balance the load across all available CPU cores, it tries to keep the priority tasks on a select group of cores while aiming to keep the other cores idle in order to allow for the power allowance to be used by those few turbo-capable cores with the high priority work...

Whether you like it or not, the Linux kernel's x86 32-bit support has already begun suffering some minor forms of bit rot. Most kernel developers are no longer actively testing x86-32 and distribution vendors are beginning to drop 32-bit support. The latest example of x86 32-bit's effectively demoted state is some buggy undefined behavior functionality living within the mainline kernel for the past year since the Meltdown mitigations landed...
