MIPS: Replace setup_irq() by request_irq()

2020-03-05T15:47:35Z

request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq(). remove_irq() has been replaced by free_irq() as well. There were build error's during previous version, couple of which was reported by kbuild test robot of which one was reported by Thomas Bogendoerfer as well. There were a few more issues including build errors, those also have been fixed.

MIPS: Move several variables from .bss to .init.data

2009-12-17T01:57:27Z

Several static uninitialized variables are used in the scope of __init functions but are themselves not marked as __initdata. This patch is to put those variables to where they belong and to reduce the memory footprint a little bit. Also, a couple of lines with spaces instead of tabs were fixed.

[MIPS] IRQ cleanups

2006-11-30T01:14:46Z

This is a big irq cleanup patch. * Use set_irq_chip() to register irq_chip. * Initialize .mask, .unmask, .mask_ack field. Functions for these method are already exist in most case. * Do not initialize .startup, .shutdown, .enable, .disable fields if default routines provided by irq_chip_set_defaults() were suitable. * Remove redundant irq_desc initializations. * Remove unnecessary local_irq_save/local_irq_restore, spin_lock. With this cleanup, it would be easy to switch to slightly lightwait irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ(). Though whole this patch is quite large, changes in each irq_chip are not quite simple. Please review and test on your platform. Thanks. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle
