Subject: [PATCH v2 0/2] Simplify kallsyms offset table generation
Date: Fri, 16 Jan 2026 10:34:00 +0100	[thread overview]
Message-ID: <20260116093359.2442297-4-ardb+git@google.com> (raw)

From: Ard Biesheuvel <ardb@kernel.org>

v2:
- implement minimal PC32 support for MIPS so it can tolerate the symbol
  references emitted by kallsyms
- use signed decimal to represent the offset, so that symbols appearing
  before _text can be represented correctly.
- add Kees's ack
