Good morning, it's Thursday, September 24th, 2026, and this is your Linux Kernel briefing.
The takeaway is narrow but important reliability work for PA-RISC systems heading into the 7-point-3 release candidate 5 window, with crash avoidance as the top priority.
First, stability on 64-bit kernels. The kernel stack size is being increased to 32 kilobytes, a direct fix for crashes seen under deep call paths. If you maintain drivers, filesystem code, or other low-level paths on this architecture, this change gives you more headroom for nested calls and interrupts. It lowers…
Second, boot configuration correctness. Early boot parameter parsing is now handled in the architecture setup routine, which allows huge page settings to take effect as intended. For developers testing or deploying large-memory configurations, this means more predictable startup behavior and no need for late…
Third, maintainability and code health, all tracked in merge 62f4c99. The unwind code now uses the standard library binary search instead of a hand-written version, which reduces the risk of subtle logic errors and makes future review simpler. In parallel, an unused compatibility context header has been…
