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/compat.h
• asm/signal.h

Detected Declarations

• struct __new_sigaction32
• struct __old_sigaction32

Annotated Snippet

struct __new_sigaction32 {
	unsigned int		sa_handler;
	unsigned int    	sa_flags;
	unsigned int		sa_restorer;     /* not used by Linux/SPARC yet */
	compat_sigset_t 	sa_mask;
};

struct __old_sigaction32 {
	unsigned int		sa_handler;
	compat_old_sigset_t  	sa_mask;
	unsigned int    	sa_flags;
	unsigned int		sa_restorer;     /* not used by Linux/SPARC yet */
};

Annotation

• Immediate include surface: `linux/compat.h`, `asm/signal.h`.
• Detected declarations: `struct __new_sigaction32`, `struct __old_sigaction32`.
• Atlas domain: Architecture Layer / arch/sparc.
• 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.
