f30a6484f1 m68k/irq: Remove obsolete support for user vector interrupt fixups 
It was used on Apollo only, before its conversion to genirq.

dda7535912 m68k/sun3: Convert Sun3/3x to genirq 
Replace the custom irq handler that masks the irq and calls do_IRQ(), and
the unmasking in the individual handlers, by handle_level_irq().

edb347256c m68k/irq: Add m68k_setup_irq_controller() 
This is a wrapper around m68k_setup_irq_chip() that discards its dummy

c288bf2533 m68k/irq: Rename irq_controller to irq_chip 
Make it more similar to the genirq version:
  - Remove lock (unused as we don't do SMP anyway),
  - Prepend methods with irq_,
  - Make irq_startup() return unsigned int.

This patch contains the following possible cleanups:
- make the following needlessly global code static:
  - config.c: sun3_bootmem_alloc()
  - config.c: sun3_sched_init()
  - dvma.c: dvma_page()
  - idprom.c: struct Sun_Machines[]
  - mmu_emu.c: struct ctx_alloc[]
  - sun3dvma.c: iommu_use[]
  - sun3ints.c: led_pattern[]
- remove the unused sbus.c

2850bc2737 [PATCH] m68k pt_regs fixes 
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.

3171a0305d [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem) 
Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390
timer interrupt handler with this change.

Currently update_times() calculates ticks by "jiffies - wall_jiffies", but
callers of do_timer() should know how many ticks to update.  Passing ticks
get rid of this redundant calculation.  Also there are another redundancy
pointed out by Martin Schwidefsky.

This cleanup make a barrier added by
5aee405c66 needless.  So this patch removes
it.

As a bonus, this cleanup make wall_jiffies can be removed easily, since now
wall_jiffies is always synced with jiffies.  (This patch does not really
remove wall_jiffies.  It would be another cleanup patch)

1da177e4c3 Linux-2.6.12-rc2 
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!
