When building modules (as well as the kernel) with ARCH=um, the options -Dsetjmp=kernel_setjmp and -Dlongjmp=kernel_longjmp are passed to the C preprocessor for C files. This causes the setjmp and longjmp used in module/lua/ldo.c to be kernel_setjmp and kernel_longjmp respectively in the object file. However, the setjmp and longjmp that is intended to be called is defined in an architecture dependent assembly file under the directory module/lua/setjmp. Since it is an assembly and not a C file, the preprocessor define is not given and the names do not change. This becomes an issue when modpost is trying to create the Module.symvers and sees no defined symbol for kernel_setjmp and kernel_longjmp. To fix this, if the macro CONFIG_UML is defined, then setjmp and longjmp macros are undefined. When building with ARCH=um for x86 sub-architectures, CONFIG_X86 is not defined. Instead, CONFIG_UML_X86 is defined. Despite this, the UML x86 sub-architecture can use the same object files as the x86 architectures because the x86 sub-architecture UML kernel is running with the same instruction set as CONFIG_X86. So the modules/Kbuild build file is updated to add the same object files that CONFIG_X86 would add when CONFIG_UML_X86 is defined.
