It was submitted (but not in patch form) by Brendan Trotter http://www.mail-archive.com/linuxbios@linuxbios.org/msg08771.html
Here it is in patch form.
- data32 lgdt %cs:gdtptr
- movl $gdtptr, %ebx
- lgdt %cs:(%bx)
It removes the first line, which causes some compilers to give a "truncated gdtptr" error, and replaces it with an intermediate load step. I think it should be tested by someone with the "working" compiler, to compare the output.
Please repost with a Signed-off-by.
I was hoping Brendan Trotter would supply that, since it was his work.
It
could be considered trivial, though, if the compiler output is the same.
Yes, I guess this is trivial enough so you can post it with your Signed-off-by, but if Brendan (CC'd) can re-send with a Signed-off-by that's fine too, of course.
I tried it on a different compiler (4.1.1) and the patch builds, but won't boot on qemu. Without the patch it builds and boots.
I'll just upgrade my compiler.
