[PATCH 06/10] x86/tracing: Move page fault trace points to generic
From: Nam Cao <hidden>
Date: 2025-03-11 17:05:30
Also in:
lkml
Subsystem:
the rest, tracing, x86 architecture (32-bit and 64-bit), x86 mm · Maintainers:
Linus Torvalds, Steven Rostedt, Masami Hiramatsu, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen, Andy Lutomirski, Peter Zijlstra
Page fault trace points are interesting for other architectures as well.
Move them to be generic.
