No objection but kind of déjà vu: https://lists.nongnu.org/archive/html/qemu-devel/2019-01/msg03427.html I still think the interface of load_elf may need to be rethinked but I don't know a good way. This could be fixed in a later patch causing more code churn again though, so if there's a way to fix this it might be a good opportunity now. But I don't want to hold your patch series back so unless someone has a good idea to avoid this situation then we have to live with it.

Another thing that I noticed is "endian argument" that it seems everyone uses in a different way: 0, 1, true, false, bigendian, etc. Would c enumeration help? This looks to me like a time ticking bomb. Just to add that some platforms like MIPS and SPARC must load elfs of more than one value of EM_MACHINE (in MIPS case, EM_MIPS and EM_NANOMIPS) and current load_elf() interface offers only clumsy solutions/workarounds in these cases.

Sorry I didn't respond earlier, this was a very short delay (patch posted yesterday, pull request sent today). My original patch was much less intrusive: https://www.mail-archive.com/qemu-devel@nongnu.org/msg673762.html I don't find comfortable being listed as the author of the current patch.

I can also confirm Aleksandar's words about ungraceful exits. We receive quite frequently questions from end users: "Can't you detect these wrong combination and output an informative message (and not segfault or hang), and help us that way correct our usage mistakes?" We have the hardest time explaining them that craching/hanging is the best we can do. This give us (MIPS/QEMU) really bad publicity. Probably the confidence in the whole QEMU suffers to some extent. This patch will be helpful to resolve these cases in much better way. All in all: Reviewed-by: Aleksandar Rikalo <aleksandar.rikalo@rt-rk.com>
