Hi, When building an out of tree module (I expect it happens in tree as well) for ARCH=um, I'm seeing options like -Dsetjmp=kernel_setjmp being sent to the compiler. This is causing the zfs[1] kernel module to fail to build because it uses a function internally called setjmp. Usually this wouldn't be a problem because both the definition and calls for setjmp would be renamed. However, setjmp is defined in an assembly file and so is not getting renamed, causing modpost to bork because it can't find the symbol named "kernel_setjmp".
I've fixed this in the zfs code base by using "#undef setjmp" when CONFIG_UML_X86 is defined. But I'm thinking a better fix would be for the ARCH=um build to not send these name redefinitions in the first place. I'm thinking a possible solution is to only send those options to the compiler when not compiling module code or even better only code under arch/um. Or would this be too much of a pain to fix?
