[PATCH] powerpc: Fix setting MPIC priority

2005-11-19T03:19:13+00:00

Trying to set the priority would just disable the interrupt due to an
incorrect mask used. We rarely use that call, in fact, I think only in
the powermac code for the cmd-power key combo that triggers xmon. So it
got unnoticed for a while.

powerpc: Fix incorrect timer register addresses in mpic.c

2005-10-26T11:55:33+00:00

We were computing the wrong address for the MPIC timer registers,
so when we went to initialize them we would have been hitting some
unrelated ioremap... oops.

powerpc: Move smp_mpic_message_pass into mpic.c

2005-10-20T07:09:51+00:00

Having it here rather than in arch/ppc64/kernel/smp.c means that
we can use it on 32-bit SMP systems easily with ARCH=powerpc.

powerpc: Get merged kernel to compile and run on 32-bit SMP powermac.

2005-10-01T03:49:08+00:00

This updates the powermac SMP code to use the mpic driver instead of
the openpic driver and fixes the SMP-dependent context switch code.
We had a subtle bug where we were using interrupt numbers 256-259 for
IPIs, but ppc32 had NR_IRQS = 256.  Moved the IPIs down to use interrupt
numbers 252-255 instead.

powerpc: Merge enough to start building in arch/powerpc.

2005-09-26T06:04:21+00:00

This creates the directory structure under arch/powerpc and a bunch
of Kconfig files.  It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac.  This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.

For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel.  This makes some minor changes
to files in those directories and files outside arch/powerpc.

The boot directory is still not merged.  That's going to be interesting.
