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.

Dependency Surface

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

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

void sm4_ce_expand_key(const u8 *key, u32 *rkey_enc, u32 *rkey_dec,
		       const u32 *fk, const u32 *ck);

void sm4_ce_crypt_block(const u32 *rkey, u8 *dst, const u8 *src);

void sm4_ce_cbc_enc(const u32 *rkey_enc, u8 *dst, const u8 *src,
		    u8 *iv, unsigned int nblocks);

Annotation

• 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.
