Linux drops its last escape hatch for CPUs without a reliable TSC

The Linux kernel is making the x86 Time Stamp Counter (TSC) mandatory, removing the final option to build a kernel without it. The change ends Linux’s decades-long compatibility path for very old processors and lets the kernel discard timing code that detected, calibrated, and worked around missing or unreliable TSC hardware.
