commit 63238f2cc5518e1c45a3418fc0ac0f560dafe7ef upstream.
The following build error is seen if CONFIG_32BIT is undefined, CONFIG_64BIT is defined, and CONFIG_MIPS32_O32 is undefined.
asm/syscall.h: In function 'mips_get_syscall_arg': arch/mips/include/asm/syscall.h:32:16: error: unused variable 'usp' [-Werror=unused-variable] cc1: all warnings being treated as errors
