Linux Kernel Daily: Merge Window Cleanup Wave
The seven point three merge window brought a coordinated push to retire legacy code paths across architectures and subsystems, alongside deeper hardware description consolidation in x86 and SoC trees. The throughline is deprecation and unification rather than new features.

Good morning. It's August 19th, and today's kernel activity shows a deliberate cleanup cycle taking shape across the tree.
The clearest pattern is deprecation with a plan. Arnd Bergmann's ARM SoC pull, commit b-d-5-f-4-8-5, marks twenty-two legacy board files, several old CPU cores like the Cortex M3 and M4, and even old userspace binary formats as deprecated. Nothing's deleted yet — this is a staged removal, giving downstream users one…
Second theme: unification of hardware identification code. On x86, Boris Petkov's CPU pull consolidates how the kernel reads and represents CPUID data, and removes the old static CPU has API entirely. That's paired with page table code across x86 memory management being converted to a common ptdesc representation,…
Third theme: config and API consolidation for time-related code. Thomas Gleixner's VDSO pull renames "have generic VDSO" to "VDSO datastore" and makes it auto-selected instead of manually configured per architecture, while tightening compat 32-bit time guards so legacy code doesn't leak into architectures that don't…
Worth flagging separately: the resource control fixes from Reinette Chatre, folded into commit…
What's next: watch for the…
