4Subject: [PATCH] compaction: make tracepoints condtional on CONFIG_COMPACTION

6When building against a v5.19 mips kernel, the following errors

56The root cause appears to be that this particular mips kernel does not
57have CONFIG_COMPACTION avaiable, and hence we end up with the struct
58declaration within this tracepoint, and then conflicting types.
59
60While putting the conditional around only compaction_migratepages seemed
61sufficient to get the build working, it doesn't look like any of the
62tracepoints should be valid, so we extend it to all definitions.
