-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[].
