nm - list symbols from object files.

0000000000010900 ? __exception_decrementer

this line shows me the the exception handler for
the decrementer interrupt is located at offset 0x10900
but it should located at 0x00900 (MSR[IP]=0).

In other words:
A decrementer exception is vectored to 0x00900 but
the belonging handler waits at 0x10900.

or am i completely wrong?
