* powerpc/fsl-pci: Fix MSI support on 83xx platformsKumar Gala2010-10-14
| | | | | | | | | | | | | | | | | | The following commit broke 83xx because it assumed the 83xx platforms exposed the "IMMR" address in BAR0 like the 85xx/86xx/QoriQ devices do: commit 3da34aae03d498ee62f75aa7467de93cce3030fd Author: Kumar Gala <galak@kernel.crashing.org> Date: Tue May 12 15:51:56 2009 -0500 powerpc/fsl: Support unique MSI addresses per PCIe Root Complex However that is not true, so we have to search through the inbound window settings on 83xx to find which one matches the IMMR address to determine its PCI address.

* powerpc/pseries/xics: Use cpu_possible_mask rather than cpu_all_maskNishanth Aravamudan2010-10-13
| | | | | | | | | | | | | | Current firmware only allows us to send IRQs to the first processor or all processors. We currently check to see if the passed in mask is equal to the all_mask, but the firmware is only considering whether the request is for the equivalent of the possible_mask. Thus, we think the request is for some subset of CPUs and only assign IRQs to the first CPU (on systems without irqbalance running) as evidenced by /proc/interrupts. By using possible_mask instead, we account for this and proper interleaving of interrupts occurs.

* powerpc/pci: Fix return type of BUID_{HI,LO} macrosNishanth Aravamudan2010-10-13
| | | | | | | | | | | | | | | | BUID_HI and BUID_LO are used to pass data to call_rtas, which expects ints or u32s. But the macro doesn't cast the return, so the result is still u64. Use the upper_32_bits and lower_32_bits macros that have been added to kernel.h. Found by getting printf format errors trying to debug print the args, no actual code change for 64 bit kernels where the macros are actually used.

* powerpc/pseries: Partition migration in the kernelNathan Fontenot2010-10-13
| | | | | | | | | | | | | | | | Enable partition migration in the kernel. To do this a new sysfs file, /sys/kernel/mobility/migration, is created. In order to initiate a migration the stream id (generated by the HMC managing the system) is written to this file. After a migration occurs, and what is the majority of this code, the device tree needs to be updated for the new system the partition is running on. This is done via the ibm,update-nodes and ibm,update-properties rtas calls which return information regarding which nodes and properties of the device tree are to be added/removed/updated.

Fix it. This fixes potential spurious 'dazed and confused' NMI messages.

I tested oprofile on Intel(R) Xeon(R) CPU E7440 reporting itself as model 29, and it runs without an issue.

| * | | | | modules: Fix module_bug_list list corruption raceLinus Torvalds2010-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With all the recent module loading cleanups, we've minimized the code that sits under module_mutex, fixing various deadlocks and making it possible to do most of the module loading in parallel. However, that whole conversion totally missed the rather obscure code that adds a new module to the list for BUG() handling. That code was doubly obscure because (a) the code itself lives in lib/bugs.c (for dubious reasons) and (b) it gets called from the architecture-specific "module_finalize()" rather than from generic code. Calling it from arch-specific code makes no sense what-so-ever to begin with, and is now actively wrong since that code isn't protected by the module loading lock any more. So this commit moves the "module_bug_{finalize,cleanup}()" calls away from the arch-specific code, and into the generic code - and in the process protects it with the module_mutex so that the list operations are now safe. Future fixups: - move the module list handling code into kernel/module.c where it belongs. - get rid of 'module_bug_list' and just use the regular list of modules (called 'modules' - imagine that) that we already create and maintain for other reasons.
