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

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

Detected Declarations

• struct pt_regs
• struct callee_regs
• function misaligned_fixup

Annotated Snippet

struct pt_regs;
struct callee_regs;

#ifdef CONFIG_ARC_EMUL_UNALIGNED
int misaligned_fixup(unsigned long address, struct pt_regs *regs,
		     struct callee_regs *cregs);
#else
static inline int
misaligned_fixup(unsigned long address, struct pt_regs *regs,
		 struct callee_regs *cregs)
{
	/* Not fixed */
	return 1;
}
#endif

Annotation

• Detected declarations: `struct pt_regs`, `struct callee_regs`, `function misaligned_fixup`.
• Atlas domain: Architecture Layer / arch/arc.
• 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.
