+Subject: [PATCH] mips: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE
+
+FORTIFY_SOURCE detects various overflows at compile and run time.
+(6974f0c4555e ("include/linux/string.h:
+add the option of fortified string.h functions)
+
+ARCH_HAS_FORTIFY_SOURCE means that the architecture can be built and
+run with CONFIG_FORTIFY_SOURCE.
+
+Since mips can be built and run with that flag,
+select ARCH_HAS_FORTIFY_SOURCE as default.

+Subject: [PATCH] MIPS: Fix exception handler memcpy()
+
+The exception handler subroutines are declared as a single char, but
+when copied to the required addresses the copy length is 0x80.
+
+When range checks are enabled for memcpy() this results in a build
+failure, with error messages such as:
+
+In file included from arch/mips/mti-malta/malta-init.c:15:
+In function 'memcpy',
+ inlined from 'mips_nmi_setup' at arch/mips/mti-malta/malta-init.c:98:2:
+include/linux/string.h:376:4: error: call to '__read_overflow2' declared with attribute error: detected read beyond size of object passed as 2nd parameter
+ 376 | __read_overflow2();
+ | ^~~~~~~~~~~~~~~~~~
+
+Change the declarations to use type char[].
