strange problem with int64_t variables

[Gabor Kovesdan]

Hi,

I have two int64_t variables in kernel code, first is stored internally 
and the second one is passed from a syscall argument. When I print them 
with printf %lld modifier, the internal one behaves correctly but the 
other one I pass from a syscall has a corrupted value. If I pass 1, it 
prints out 3735348794091372545. I'm not doing anything special with it 
just reading it out from the struct that was generated with make sysent. 
Any ideas?

Thanks,
Gabor
