-Subject: [PATCH] Allow using external builds of the compiler-rt profile lib
-
-This changes the bootstrap config `target.*.profiler` from a plain bool
-to also allow a string, which will be used as a path to the pre-built
-profiling runtime for that target. Then `profiler_builtins/build.rs`
-reads that in a `LLVM_PROFILER_RT_LIB` environment variable.

-Subject: [PATCH] bootstrap: config: fix version comparison bug
-
-Rust requires a previous version of Rust to build, such as the current version, or the
-previous version.  However, the version comparison logic did not take patch releases
-into consideration when doing the version comparison for the current branch, e.g.
-Rust 1.71.1 could not be built by Rust 1.71.0 because it is neither an exact version
-match, or the previous version.
-
-Adjust the version comparison logic to tolerate mismatches in the patch version.
-
-Signed-off-by: Ariadne Conill <ariadne@dereferenced.org>
-(cherry picked from commit 31a81a08786826cc6e832bd0b49fb8b934e29648)

+Subject: [PATCH] bootstrap: only show PGO warnings when verbose
+
+Building rustc with `--rust-profile-use` is currently dumping a lot of
+warnings of "no profile data available for function" from `rustc_smir`
+and `stable_mir`. These simply aren't exercised by the current profile-
+gathering steps, but that's to be expected for new or experimental
+functionality. I think for most people, these warnings will be just
+noise, so it makes sense to only have them in verbose builds.
