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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/kvm_host.h
• x86.h

• Detected declarations: `function Copyright`, `function kvm_hv_get_vpindex`, `function kvm_hv_hypercall_enabled`, `function kvm_hv_synic_has_vector`, `function kvm_hv_synic_auto_eoi_set`, `function kvm_hv_has_stimer_pending`, `function kvm_hv_invtsc_suppressed`, `function kvm_hv_vcpu_purge_flush_tlb`, `function guest_hv_cpuid_has_l2_tlb_flush`, `function kvm_hv_is_tlb_flush_hcall`.
• Atlas domain: Architecture Layer / arch/x86.
• 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.
