+Subject: [PATCH] identify native riscv64 hosts as lnxriscv64
+
+dev/make/identify_os.sh only knows x86_64 and aarch64, so on a native
+riscv64 Linux host it prints "Unknown architecture: riscv64". The
+lnxriscv64 build is otherwise complete (dev/make/function_definitions/
+lnxriscv64.mk, compiler_definitions/clang.ref.riscv64.mk), but upstream
+CI only builds it cross-compiled from x86_64, where the host identifies
+as lnx32e and the gap is never hit. Natively, two things break:
+
+- `make daal PLAT=lnxriscv64` fails in _release_nuspec, because
+  deploy/nuget/prepare_dal_nuget.sh calls identify_os.sh itself and has
+  no lnxriscv64 branch either:
+
+      ./deploy/nuget/prepare_dal_nuget.sh: line 56: [: too many arguments
+      Unknown platform Unknown architecture: riscv64
+      make: *** [makefile:1109: _release_nuspec] Error 1
+
+- the makefile compares PLAT against IDENTIFIED_PLAT to set
+  COMPILER_is_cross, so a native build is treated as a cross build and
+  clang is given --target=riscv64-linux-gnu instead of its host triple.
+
+Map riscv64 to lnxriscv64 in identify_os.sh, and give
+prepare_dal_nuget.sh a lnxriscv64 branch mirroring lnxarm with the
+lib/riscv64 release directory the makefile already uses
+(ARCH_DIR_ONEDAL = riscv64).
+
+Upstream-Status: To upstream [not yet submitted; upstream CI only cross-compiles lnxriscv64 from x86_64, so this native-host fix needs raising on its own]

+Subject: [PATCH] silence unused --gcc-toolchain flag on native riscv64 clang
+ builds
+
+The top-level makefile always appends `--gcc-toolchain=$(GCC_TOOLCHAIN_PATH)`
+to every C.COMPILE invocation (dev/make/common.mk), with
+GCC_TOOLCHAIN_PATH derived from `which gcc` (resolving to /usr in the
+manylinux_riscv64 image). On this native riscv64 host, with no
+`--target=` passed (clang.ref.riscv64.mk only adds one when
+COMPILER_is_cross is "yes"), clang's riscv64 driver never consults the
+GCC installation for the compile-only (`-c`) step the flag is passed
+on, so it is flagged as unused:
+
+    clang++: error: argument unused during compilation:
+    '--gcc-toolchain=/usr' [-Werror,-Wunused-command-line-argument]
+    make: *** [makefile:567: .../daal_strings.o] Error 1
+
+-Werror (set right alongside in COMPILER.lnx.clang) turns that into a
+hard build failure for every translation unit. Upstream already works
+around the identical situation for icx's -static-libstdc++ flag
+(COMPILER.lnx.icx in dev/make/compiler_definitions/icx.mkl.32e.mk also
+pairs -Werror with a `-Wno-unused-command-line-argument` for a flag
+that is unused at compile time but still needed at link time); do the
+same here instead of dropping -Werror or the toolchain flag.
+
+Upstream-Status: Inappropriate [this build-system flag combination is only exercised by a native (non-cross) riscv64 host, which upstream CI never runs]
