    SubjectRe: [PATCH] [CAN-2004-1144] Fix int 0x80 hole in 2.4 x86-64 linux kernels
    Hi Andi,

    Although I don't know about x86_64 assembly, I know x86 and I wonder
    how this patch would do anything. I would personnaly have written something
    more like :

    + movzl %eax,%rax

    Once again, I may be wrong, but I really don't understand at all then.
    Could you please either confirm or detail a bit more ?

    thanks in advance,
    Willy
