Hi,
with kdump, file offsets are printed as two ints on 32-bit systems.
This diff should fix that and print a single long long.
Tested on vax and hppa. Strange things is that hppa prints a trailing
int for lseek(2). Have to dig into that. This has nothing to do with
fancy mode, since it is also printed with -n.
Here a sample of the test I used:
#include <sys/mman.h>
#include <unistd.h>
main()
{
mmap(1,2,3,4,5,0x8000000090000000LL);
lseek(3,0x12345678abcdef12LL,1);
}
Hope I got the tricky sign-extends all covered.
