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.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `asm/page.h`, `asm/memory.h`, `asm/mmu.h`, `asm/cpufeature.h`, `asm/alternative.h`, `linux/pgtable.h`, `asm/pgalloc.h`, `asm/cache.h`.
• Detected declarations: `struct kvm`, `function kvm_update_va_mask`, `function vcpu_has_cache_enabled`, `function __clean_dcache_guest_page`, `function __invalidate_icache_max_range`, `function __invalidate_icache_guest_page`, `function kvm_get_vmid_bits`, `function kvm_read_guest_lock`, `function kvm_write_guest_lock`, `function is`.
• Atlas domain: Architecture Layer / arch/arm64.
• Implementation status: source implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
