2011-12-10m68k/mac: cleanup mac_irq_pendingFinn Thain1-9/+0
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. Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2011-12-10m68k/mac: cleanup mac_clear_irqFinn Thain1-8/+0
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.

2007-05-04m68k: Mac IRQ cleanupFinn Thain1-2/+0
There are no slow IRQs on Macs since Roman Zippel's IRQ reorganisation that went into 2.6.16 and removed mac_irq_list[] and the do_mac_irq_list() dispatcher. (They were implemented in do_mac_irq_list() by lowering the IPL.) Hence there's no more use for mutual exclusion in the Mac interrupt dispatchers. Remove it.

2007-05-04m68k: Mac IRQ prepFinn Thain1-9/+10
Make sure that there are no slot IRQs asserted before leaving the nubus handler. If there are and we don't then the nubus gets wedged because this prevents a CA1 transition, which means no more nubus IRQs. Make the interrupt dispatch loops terminate sooner. Explicitly initialise the VIA latches to make the code more easily understood. Also some cleanups.

2006-10-07[PATCH] m68k pt_regs fixesAl Viro1-3/+3
m68k_handle_int() split in two functions: __m68k_handle_int() takes pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs *. Places where we used to call m68k_handle_int() recursively with the same pt_regs have simply lost the second argument, the rest is switched to __m68k_handle_int(). The rest of patch is just dropping pt_regs * where needed. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
