sys-kernel/linux-{image,sources}-redcore-lts :HEADmaster
* version bump to v4.14.75 * adjust MuQSS v0.162 CPU scheduler to linux-hardened and enable it by default * add BFQ-SQ v8r12 I/O scheduler and enable it by default * lower HZ to 100 (recommended value for MuQSS enabled kernels) * disable dynamic ticks (MuQSS itself is a tickless scheduler, so no longer required)
