Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

• CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• function setup_power_save
• function check_smt_enabled
• function setup_tlb_core_data
• function exc_lvl_early_init
• function emergency_stack_init
• function kvm_cma_reserve

Annotation

• Detected declarations: `function setup_power_save`, `function check_smt_enabled`, `function setup_tlb_core_data`, `function exc_lvl_early_init`, `function emergency_stack_init`, `function kvm_cma_reserve`.
• Atlas domain: Architecture Layer / arch/powerpc.
• Implementation status: source implementation candidate.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
