2015-09-15powerpc, irq: Use access helper irq_data_get_affinity_mask()Jiang Liu
Use access helper irq_data_get_affinity_mask() so we can move the affinity mask to irq_common_data.

2015-07-16treewide: Use helper function to access irq_data->msi_descJiang Liu
Use irq_data access helper to access irq_data->msi_desc, so we can move msi_desc from struct irq_data into struct irq_common_data later.

2015-02-13powerpc: use %*pb[l] to print bitmaps including cpumasks and nodemasksTejun Heo
printk and friends can now format bitmaps using '%*pb[l]'. cpumask and nodemask also provide cpumask_pr_args() and nodemask_pr_args() respectively which can be used to generate the two printf arguments necessary to format the specified cpu/nodemask. * Spurious if (len > 1) test dropped from shared_cpu_map_show().

2014-11-23PCI/MSI: Rename mask/unmask_msi_irq treewideThomas Gleixner
The PCI/MSI irq chip callbacks mask/unmask_msi_irq have been renamed to pci_msi_mask/unmask_irq to mark them PCI specific. Rename all usage sites. The conversion helper functions are kept around to avoid conflicts in next and will be removed after merging into mainline. Coccinelle assisted conversion. No functional change.

2013-02-08powerpc: fix ics_rtas_init and start_secondary section mismatchDaniel Borkmann
It seems, we're fine with just annotating the two functions. Thus, this fixes the following build warnings on ppc64: WARNING: arch/powerpc/sysdev/xics/built-in.o(.text+0x1664): The function .ics_rtas_init() references the function __init .xics_register_ics(). This is often because .ics_rtas_init lacks a __init annotation or the annotation of .xics_register_ics is wrong. WARNING: arch/powerpc/sysdev/built-in.o(.text+0x6044): The function .ics_rtas_init() references the function __init .xics_register_ics(). This is often because .ics_rtas_init lacks a __init annotation or the annotation of .xics_register_ics is wrong. WARNING: arch/powerpc/kernel/built-in.o(.text+0x2db30): The function .start_secondary() references the function __cpuinit .vdso_getcpu_init(). This is often because .start_secondary lacks a __cpuinit annotation or the annotation of .vdso_getcpu_init is wrong.

2011-04-20powerpc/xics: Move irq_host matching into the ics backendMichael Ellerman
An upcoming new ics backend will need to implement different matching semantics to the current ones, which are essentially the RTAS ics backends. So move the current match into the RTAS backend, and allow other ics backends to override.

2011-04-20powerpc/xics: Rewrite XICS driverBenjamin Herrenschmidt
This is a significant rework of the XICS driver, too significant to conveniently break it up into a series of smaller patches to be honest. The driver is moved to a more generic location to allow new platforms to use it, and is broken up into separate ICP and ICS "backends". For now we have the native and "hypervisor" ICP backends and one common RTAS ICS backend. The driver supports one ICP backend instanciation, and many ICS ones, in order to accomodate future platforms with multiple possibly different interrupt "sources" mechanisms.
