Use __do_IRQ instead. The only difference is that every controller is now assumed to have an end() routine (only xics_8259 did not). Signed-off-by: -

This factors out the common bits of arch/powerpc/xmon/start_*.c into a new nonstdio.c, and removes some stuff that was supposed to make xmon's I/O routines somewhat stdio-like but was never used. It also makes the parsing of the xmon= command line option common, so that ppc32 can now use xmon={off,on,early} also. Signed-off-by:Paul Mackerras <paulus@samba.org>

Some powermac machines were crashing in the quiesce firmware call in prom_init.c because we have just closed the OF stdin device; notably my 1999 G3 powerbook does this. To avoid this, don't close the OF stdin device on powermacs. Signed-off-by: -

This is a temporary kludge that supports adding all new memory to node 0. I will provide a more complete solution similar to that used for dynamically added CPUs in a few days. Signed-off-by:

memmap_init_zone() sets page count to 1. Before 'freeing' the page, we need to clear the count. This is the same that is done on free_all_bootmem_core() for memory discovered at boot time. Signed-off-by:

For some stupid reason I can't explain (brown paper bag is at hand), I removed the check pfn_valid() in the code that does the icache/dcache coherency on POWER4 and later. That causes us to eventually try to access non existing struct page when hashing in IO pages. Signed-off-by:

This seems to be done in other parts of the Kconfig file. Using those as an example, this should keep the MAX_ORDER block size at 16MB. Signed-off-by:

Even though we can enable and disable xmon at runtime now, there are a few places in the merge tree that call xmon and xmon_printf directly. In the case below we call die() which will call xmon if it is enabled. Also remove an unnecessary include of xmon.h in smp.c. Signed-off-by:

Oprofile was hardwiring the MMCRA sample bit to 1 but on newer cpus (eg POWER5) we want to vary it based on the group being sampled. Add a temporary workaround until people update their oprofile userspace. Signed-off-by:

On ppc64 we end up with a negative value for the data size in the memory boot message: Memory: 2035560k/2097152k available (5792k kernel code, 89564k reserved, 18014398509481632k data, 870k bss, 352k init) It turns out the section ordering of the linker script is different on ppc32 and ppc64, so just count data as _edata - _sdata which should work on both.

This adds a new thermal control framework for PowerMac, along with the implementation for PowerMac8,1, PowerMac8,2 (iMac G5 rev 1 and 2), and PowerMac9,1 (latest single CPU desktop). In the future, I expect to move the older G5 thermal control to the new framework as well. Signed-off-by:

This patch updates g5_defconfig for ARCH=powerpc in order to add the SMU support & thermal drivers to it, the pmac sound driver (works on some G5s) and replaces rivafb with nvidiafb which works better for the cards found in G5 based machines. Signed-off-by:

OK, the Fedora ppc32 and ppc64 kernels should both be arch/powerpc by tomorrow. They're booting on G5, POWER5, and my powerbook. I'll test pmac SMP and Pegasos later -- but pmac smp is known broken in arch/ppc anyway, and I'll live with a potential Pegasos regression for now; it wasn't supported officially in FC4 either. I needed to fix ppc32 initrd -- we were never setting initrd_start. Signed-off-by:
