Subject: [PATCH 0/4] kernel/panic: add more descriptive logging of kernel taints

Resend of
https://lore.kernel.org/r/cover.1711380724.git.jani.nikula@intel.com

A few years back there was a discussion about it being difficult to
remember all the taint flags [1].

Time flies. I stumbled on my old branch, brushed it up, and here it is.

I'm not entirely happy with the static buf (which was there to begin
with) or how to decide on its size. Thoughts?

BR,
Jani.

Jani Nikula (4):
  kernel/panic: return early from print_tainted() when not tainted
  kernel/panic: convert print_tainted() to use struct seq_buf internally
  kernel/panic: initialize taint_flags[] using a macro
  kernel/panic: add verbose logging of kernel taints in backtraces
