* powerpc: Make cpu_to_chip_id() available when SMP=nMichael Ellerman2013-11-20
| | | | | | | | | | | | | | | | | Up until now we have only used cpu_to_chip_id() in the topology code, which is only used on SMP builds. However my recent commit a4da0d5 "Implement arch_get_random_long/int() for powernv" added a usage when SMP=n, breaking the build. Move cpu_to_chip_id() into prom.c so it is available for SMP=n builds. We would move the extern to prom.h, but that breaks the include in topology.h. Instead we leave it in smp.h, but move it out of the CONFIG_SMP #ifdef. We also need to include asm/smp.h in rng.c, because the linux version skips asm/smp.h on UP. What a mess.

* | powerpc/powernv: Reserve the correct PE numberGavin Shan2013-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're assigning PE numbers after the completion of PCI probe. During the PCI probe, we had PE#0 as the super container to encompass all PCI devices. However, that's inappropriate since PELTM has ascending order of priority on search on P7IOC. So we need PE#127 takes the role that PE#0 has previously. For PHB3, we still have PE#0 as the reserved PE. The patch supposes that the underly firmware has built the RID to PE# mapping after resetting IODA tables: all PELTM entries except last one has invalid mapping on P7IOC, but all RTEs have binding to PE#0. The reserved PE# is being exported by firmware by device tree. Signed-off-by: Gavin Shan <shangw@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* powerpc/eeh: Use partial hotplug for EEH unaware driversGavin Shan2013-07-24
| | | | | | | | | | | | | | | | | | | | | | When EEH error happens to one specific PE, some devices with drivers supporting EEH won't except hotplug on the device. However, there might have other deivces without driver, or with driver without EEH support. For the case, we need do partial hotplug in order to make sure that the PE becomes absolutely quite during reset. Otherise, the PE reset might fail and leads to failure of error recovery. The current code doesn't handle that 'mixed' case properly, it either uses the error callbacks to the drivers, or tries hotplug, but doesn't handle a PE (EEH domain) composed of a combination of the two. The patch intends to support so-called "partial" hotplug for EEH: Before we do reset, we stop and remove those PCI devices without EEH sensitive driver. The corresponding EEH devices are not detached from its PE, but with special flag. After the reset is done, those EEH devices with the special flag will be scanned one by one.

* powerpc: Delete __cpuinit usage from all usersPaul Gortmaker2013-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. This removes all the powerpc uses of the __cpuinit macros. There are no __CPUINIT users in assembly files in powerpc.
