# HEAD: b2747f108b8034271fd5289bd8f3a7003e0775a3 x86/boot: Don't add the EFI stub to targets, again

Misc fixes:

- Fix the 8 bytes get_user() logic on x86-32

- Fix build bug that creates weird & mistaken target directory under arch/x86/

Thanks,

Ingo

- Fix the 8 bytes get_user() logic on x86-32

This is clearly a fix, but I think it's a bit ugly.

Instead of adding _more_ special cases for size 8, we could just remove them.

Making the 8-bit two-word versions just clear %ecx before doing the first load means that all the exception handling becomes entirely unified.

And then you can just use a nice macro for all the user accesses, and the #ifdefs go away entirely for all exception handling. All that remains is the "do I do a 'movq' or an xor and two movl's" question.

Something ENTIRELY UNTESTED like this, IOW.

I did check that it seemed to generate sane code on both 32-bit and 64-bit, but no _actual_ testing.

Hohumm, looks ok to me. And running it a bit with selftests looks good too.
