2022-02-22MIPS: pci-ar2315: Constify static irq_domain_opsRikard Falkeborn1-1/+1
The only usage of ar2315_pci_irq_domain_ops is to pass its address to irq_domain_add_linear() which takes a pointer to const struct irq_domain_ops. Make it const to allow the compiler to put it in read-only memory. Signed-off-by: Rikard Falkeborn <rikard.falkeborn@gmail.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>

2020-09-11dma-direct: rename and cleanup __phys_to_dmaChristoph Hellwig1-1/+1
The __phys_to_dma vs phys_to_dma distinction isn't exactly obvious. Try to improve the situation by renaming __phys_to_dma to phys_to_dma_unencryped, and not forcing architectures that want to override phys_to_dma to actually provide __phys_to_dma.

2015-09-16genirq: Remove irq argument from irq flow handlersThomas Gleixner1-1/+1
Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help!
