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/cpumask.h

Detected Declarations

• struct arch_tlbflush_unmap_batch

Annotated Snippet

struct arch_tlbflush_unmap_batch {
#ifdef CONFIG_ARM64_ERRATUM_4193714
	/*
	 * Track CPUs that need SME DVMSync on completion of this batch.
	 * Otherwise, the arm64 HW can do tlb shootdown, so we don't need to
	 * record cpumask for sending IPI
	 */
	cpumask_var_t cpumask;
#endif
};

#endif /* _ARCH_ARM64_TLBBATCH_H */

Annotation

• Immediate include surface: `linux/cpumask.h`.
• Detected declarations: `struct arch_tlbflush_unmap_batch`.
• Atlas domain: Architecture Layer / arch/arm64.
• 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.
