genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

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!

m68k/irq: Prepare irq handlers for irq argument removal

2015-08-01T06:07:22+00:00

The irq argument of most interrupt flow handlers is unused or merily
used instead of a local variable. The handlers which need the irq
argument can retrieve the irq number from the irq descriptor.

Search and update was done with coccinelle and the invaluable help of
Julia Lawall.

m68k/mac: oss irq fixes

2011-12-10T18:52:47+00:00

The IOP driver calls into the OSS driver to enable its IRQ. This undesirable coupling between drivers only exists because the OSS driver doesn't correctly handle all of its machspec IRQs.

Fix OSS handling of enable/disable for VIA1 IRQs (8 thru 15) which includes MAC_IRQ_ADB.

Back when I implemented pmac_zilog support I redefined IRQ_MAC_SCC incorrectly. Change this to a machspec IRQ so that it works on OSS.

Clean up the unused OSS audio IRQ and OSS_IRQLEV_* cruft that only confuses things.

Fix the OSS description in macints.c and remove an obsolete comment.

Don't enable the VIA1 irq before registering the handler.

m68k/mac: cleanup mac_irq_pending

2011-12-10T18:52:46+00:00

mac_irq_pending() has only one caller (mac_esp.c). Nothing tests for Baboon, PSC or OSS pending interrupts. Until that need arises, let's keep it simple and remove all the unused abstraction. Replace it with a routine to check for SCSI DRQ.

m68k/mac: cleanup mac_clear_irq

2011-12-10T18:52:45+00:00

mac_clear_irq() is dead code and has been dead for as long as I can recall. On certain Mac models, certain irqs can't be cleared this way. Outside of irq dispatch, this code appears be unusable without busy loops or worse, and for irq dispatch we duplicate the same logic. Remove mac_clear_irq() and supporting code.
