Marcel Moolenaar 5da7ea0a89 In powerpc_get_pcpup(), make the inline assembly statement ... volatile so that the compiler won't perform CSE. For SMP, this may result in us accessing the wrong PCPU and as such results in a bogus curthread value. Note that getting curthread is not quite MP-safe in the sense that it requires two instructions that aren't performed atomically. The first instruction gets the address of the PCPU structure and the second instruction dereferences that pointer to get curthread. If a thread is switched-out in between these instructions and switched-in on a different CPU, we still get the wrong curthread.		2008-09-16 16:28:51 +00:00
