Modified files:
sys/amd64/amd64 exception.S
Log:
Restored FAKE_MCOUNT() and MEXITCOUNT invocations and adjusted them for
amd64 as necessary. This is routine, except:
- the FAKE_MCOUNT($bintr) in doreti was missing the '$'. This gave a
a garbage address made up of padding bytes (with the nop byte 0x90 as
the MSB) instead of the intended address of bintr. This accidentally
worked on i386's because (0x90 << 24) is close enough to bintr, but
it doesn't work on amd64's because (0x90 << 56) is much further away
from bintr.
- the FAKE_MCOUNT($btrap) in calltrap was similarly broken. It hasn't
been needed since FreeBSD-1, so just delete it.
