Subject: [PATCH v2 0/3] kallsyms: Rust requirements

These are the kallsyms patches we carry on the Rust patch series as
prerequisites. We were requested to submit them independently, so
here they are!

  - The first one is an improvement that may be applied even without
    the big symbol support.

  - The second adds support for "big" symbols without actually
    increasing the limit.

  - The third performs the actual increase.

Thanks!

Boqun Feng (1):
  kallsyms: avoid hardcoding the buffer size

Miguel Ojeda (2):
  kallsyms: support "big" kernel symbols
  kallsyms: increase maximum kernel symbol length to 512
