Replace trace_foo() with the new trace_call__foo() at sites already
guarded by trace_foo_enabled(), avoiding a redundant
static_branch_unlikely() re-evaluation inside the tracepoint.
trace_call__foo() calls the tracepoint callbacks directly without
utilizing the static branch again.
Original v2 series:

Parts of the original v2 series have already been merged in mainline.
This patch is being reposted as a follow-up cleanup for the remaining
unmerged pieces.
