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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.

Dependency Surface

• linux/export.h
• asm/kvm_ppc.h
• asm/kvm_book3s.h

Detected Declarations

• export kvmppc_hv_entry_trampoline
• export kvmppc_entry_trampoline

Annotation

• Immediate include surface: `linux/export.h`, `asm/kvm_ppc.h`, `asm/kvm_book3s.h`.
• Detected declarations: `export kvmppc_hv_entry_trampoline`, `export kvmppc_entry_trampoline`.
• Atlas domain: Architecture Layer / arch/powerpc.
• Implementation status: integration 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.
