condition to SLOF and Linux manages to work around the bug.  However,
the bug becomes evident now that SCSI devices also report unit
attention on reset.

SLOF also has problems dealing with unit attention conditions, so
it still will not boot even with this fix (just like OpenBIOS).

PPC: Fix sync instructions problem in SMP

In the current emulation of the load-and-reserve (lwarx) and
store-conditional (stwcx.) instructions, the internal reservation
mechanism is taken into account, however each CPU has its own
reservation information and this information is not synchronized between
CPUs to perform proper synchronization.
The following test case with 2 CPUs shows that the semantics of the
"lwarx" and "stwcx." instructions are not preserved by the emulation.
The test case does the following :
- CPU0: reserve a memory location
- CPU1: reserve the same memory location
- CPU0: perform stwcx. on the location
The last store-conditional operation succeeds while it is supposed to
fail since the reservation was supposed to be lost at the second reserve
operation.

This (one line) patch fixes this problem in a very simple manner by
removing the reservation of a CPU every time it is scheduled (in
cpu_exec()). While this is a harsh workaround, it does not affect the
guest code much because reservations are usually held for a very short
time, that is an lwarx is almost always followed by an stwcx. a few
instructions below. Therefore, in most cases, the reservation will be
taken and consumed before a CPU switch occurs. However in the rare case
where a CPU switch does occur between the lwarx and its corresponding
stwcx.  this patch solves a potential erroneous behavior of the
synchronization instructions.
