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

# SPDX-License-Identifier: GPL-2.0

#
# Match symbols in the DSO that look like VDSO_*; produce a header file
# of constant offsets into the shared object.
#
# Doing this inside the Makefile will break the $(filter-out) function,
# causing Kbuild to rebuild the vdso-offsets header file every time.
#
# Inspired by arm64 version.

Annotation

• Atlas domain: Architecture Layer / arch/s390.
• Implementation status: atlas-only.

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.
