vasilito	67db66681a	comprehensive cleanup: remove dead code in cpufreqd, iommu, numad ... Three Red Bear-original daemons had dead code that the compiler flagged. Removed it; the fix is purely deletional — no functionality changed. cpufreqd (local/recipes/system/cpufreqd/source/src/main.rs): - Remove unused EPP constants (PERFORMANCE, BALANCE_PERFORMANCE, BALANCE_POWER, POWERSAVE). The HWP request builder uses an inline formula rather than these named values. - Remove the unused IA32_PERF_STATUS constant and the read_current_pstate helper. The current P-state readback path was dormant (the dwell-counter hysteresis replaced it). - Remove the unused 'unsafe' block from the cpuid_hypervisor_bit call. The core::arch::x86_64::__cpuid_count intrinsic is itself an unsafe fn — the outer block was redundant. - Remove unused PState.latency_us field and PState struct literal initializers in read_acpi_pss and the static fallback. The field was never read. - Remove unused CpuInfo.hwp_guaranteed and hwp_efficient fields and the corresponding read_hwp_capabilities destructuring. The fields were never read after the initial extraction. iommu (local/recipes/system/iommu/source/src/interrupt.rs): - Add #[allow(dead_code)] to InterruptRemapTable.buffer. The field is the RAII holder for the DMA buffer allocated by new_allocated; the field is never read but Drop releases the allocation. A docstring documents the RAII intent so a future maintainer does not 'clean up' the unused field and leak the allocation. numad (local/recipes/system/numad/source/src/main.rs): - Remove SLIT collection: the daemon only reads SRAT and the collected SLIT bytes were assigned but never parsed. Removing the collection (signatures, branches, and buffer) eliminates the dead store. The SLIT_SIGNATURE constant goes with it. - Remove unused MAX_NUMA_NODES constant. - Remove unused SratMemory struct (SRAT Memory Affinity entry layout). The daemon only handles SratProcessorApic today. - Remove dead w[4].parse() call in read_acpi_pss. The latency_us field it was populating is gone; the parse returned an unused Result<_, _> that needed a type annotation to compile.
