The panic notifiers' callbacks execute in an atomic context, with interrupts/preemption disabled, and all CPUs not running the panic function are off, so it's very dangerous to wait on a regular spinlock, there's a risk of deadlock. Refactor the panic notifier of parisc/power driver to make use of spin_trylock - for that, we've added a second version of the soft-power function. Also, some comments were reorganized and trailing white spaces, useless header inclusion and blank lines were removed. Cc: "James E.J.

/* ** HP VISUALIZE Workstation PCI Bus Defect ** ** "HP has discovered a potential system defect that can affect ** the behavior of five models of HP VISUALIZE workstations when ** equipped with third-party or customer-installed PCI I/O expansion ** cards. The defect is limited to the HP C180, C160, C160L, B160L, ** and B132L VISUALIZE workstations, and will only be encountered ** when data is transmitted through PCI I/O expansion cards on the ** PCI bus. HP-supplied graphics cards that utilize the PCI bus are ** not affected." ** ** http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp?locale=en_US&prodTypeId=12454&prodSeriesId=44443 ** ** Product First Good Serial Number ** C200/C240 (US) US67350000 **B132L+/B180 (US) US67390000 ** C200 (Europe) 3713G01000 ** B180L (Europe) 3720G01000 ** ** Note that many boards were fixed/replaced under a free replacement ** program. Assume a machine is only "suspect" until proven otherwise. ** ** "The pci_check program will also be available as application ** patch PHSS_12295" */
