ia64: remove support for the SGI SN2 platform

2019-08-16T18:33:57Z

The SGI SN2 (early Altix) is a very non-standard IA64 platform that was at the very high end of even IA64 hardware, and has been discontinued a long time ago. Remove it because there no upstream users left, and it has magic hooks all over the kernel.

ia64/irq: Use access helper irq_data_get_affinity_mask()

2015-07-27T11:36:37Z

treewide: Use helper function to access irq_data->msi_desc

2015-07-16T21:31:37Z

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.

PCI/MSI: Rename mask/unmask_msi_irq treewide

2014-11-23T12:01:45Z

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.

PCI/MSI: Rename write_msi_msg() to pci_write_msi_msg()

PCI/MSI: Use __get_cached_msi_msg() instead of get_cached_msi_msg()

2014-10-01T18:21:23Z

Both callers of get_cached_msi_msg() start with a struct irq_data pointer, look up the corresponding IRQ number, and pass it to get_cached_msi_msg(), which then uses irq_get_irq_data() to look up the struct irq_data again to call __get_cached_msi_msg(). Since we already have the struct irq_data, call __get_cached_msi_msg() directly and skip the lookup work done by get_cached_msi_msg(). No functional change.

ia64: Validate online cpus in irq_set_affinity() callbacks

2014-03-12T12:07:40Z

The [user space] interface does not filter out offline cpus. It merily guarantees that the mask contains at least one online cpu. So the selector in the irq chip implementation needs to make sure to pick only an online cpu because otherwise: Offline Core 1 Set affinity to 0xe (is valid due to online mask 0xd) cpumask_first will pick core 1, which is offline Signed-off-by: Thomas Gleixner Cc: Peter Zijlstra Cc: Tony Luck Cc: Fenghua Yu Cc: ia64 Link: http://lkml.kernel.org/r/20140304203100.650414633@linutronix.de Signed-off-by: Thomas Gleixner
