+Subject: arm64: Handle .ARM.attributes section in linker scripts
+
+From: Nathan Chancellor <nathan@kernel.org>
+
+commit ca0f4fe7cf7183bfbdc67ca2de56ae1fc3a8db2b upstream.
+
+A recent LLVM commit [1] started generating an .ARM.attributes section
+similar to the one that exists for 32-bit, which results in orphan
+section warnings (or errors if CONFIG_WERROR is enabled) from the linker
+because it is not handled in the arm64 linker scripts.
+
+  ld.lld: error: arch/arm64/kernel/vdso/vgettimeofday.o:(.ARM.attributes) is being placed in '.ARM.attributes'
+  ld.lld: error: arch/arm64/kernel/vdso/vgetrandom.o:(.ARM.attributes) is being placed in '.ARM.attributes'
+
+  ld.lld: error: vmlinux.a(lib/vsprintf.o):(.ARM.attributes) is being placed in '.ARM.attributes'
+  ld.lld: error: vmlinux.a(lib/win_minmax.o):(.ARM.attributes) is being placed in '.ARM.attributes'
+  ld.lld: error: vmlinux.a(lib/xarray.o):(.ARM.attributes) is being placed in '.ARM.attributes'
+
+Discard the new sections in the necessary linker scripts to resolve the
+warnings, as the kernel and vDSO do not need to retain it, similar to
+the .note.gnu.property section.

+Subject: mlxsw: Add return value check for mlxsw_sp_port_get_stats_raw()
+
+From: Wentao Liang <vulab@iscas.ac.cn>
+
+commit fee5d688940690cc845937459e340e4e02598e90 upstream.
+
+Add a check for the return value of mlxsw_sp_port_get_stats_raw()
+in __mlxsw_sp_port_get_stats(). If mlxsw_sp_port_get_stats_raw()
+returns an error, exit the function to prevent further processing
+with potentially invalid data.
