The commit 97f0b13452198290799f ("tracing: add trace event for
memory-failure") introduces the selection of RAS in memory-failure.
This commit is just a tracing feature; in reality, there is no dependency
between memory-failure and RAS. RAS increases the size of the bzImage
image by 8k, which is very valuable for embedded devices.
Move the memory-failure traceing code from ras_event.h to
memory-failure.h and remove the selection of RAS.
v2->v3: https://lore.kernel.org/20251104072306.100738-3-xieyuanbin1@xxxxxxxxxx
- Change define TRACE_SYSTEM from ras to memory_failure
- Add include/trace/events/memory-failure.h to
"HWPOISON MEMORY FAILURE HANDLING" section in MAINTAINERS
- Rebase to latest linux-next source
v1->v2: https://lore.kernel.org/20251103033536.52234-2-xieyuanbin1@xxxxxxxxxx
- Move the memory-failure traceing code from ras_event.h to
memory-failure.h

These are ordered alphabetically, so it should be further up next to the other include.
