From: Benjamin Herrenschmidt <benh@kernel.crashing.org> Prevent calling of some platform functions on the clock chips of the eMac as it seems to cause it to lockup at boot. For now, add a quirk to prevent that from happening. Later, I might find out what's wrong and fix it but that doesn't seem to be important as the machine appear to work fine without running those. It's possible that Darwin doesn't run them.

2006-05-26[PATCH] PowerMac: force only suspend-to-disk to be validJohannes Berg1-0/+12
For a very long time, echoing 'standby' or 'mem' into /sys/power/state has killed the machine on powerpc. This patch fixes that. This patch adds the .valid callback to pm_ops on PowerMac so that only the suspend to disk state can be entered. Note that just returning 0 would suffice since the upper layers don't pass PM_SUSPEND_DISK down, but we handle it there regardless just in case that changes.

2006-05-19[PATCH] powerpc: Unify mem= handlingMichael Ellerman1-22/+0
We currently do mem= handling in three seperate places. And as benh pointed out I wrote two of them. Now that we parse command line parameters earlier we can clean this mess up. Moving the parsing out of prom_init means the device tree might be allocated above the memory limit. If that happens we'd have to move it. As it happens we already have logic to do that for kdump, so just genericise it. This also means we might have reserved regions above the memory limit, if we do the bootmem allocator will blow up, so we have to modify lmb_enforce_memory_limit() to truncate the reserves as well. Tested on P5 LPAR, iSeries, F50, 44p. Tested moving device tree on P5 and 44p and F50. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-05-19[PATCH] powerpc/pseries: Increment fail counter in PCI recoveryLinas Vepstas1-1/+6
When a PCI device driver does not support PCI error recovery, the powerpc/pseries code takes a walk through a branch of code that resets the failure counter. Because of this, if a broken PCI card is present, the kernel will attempt to reset it an infinite number of times. (This is annoying but mostly harmless: each reset takes about 10-20 seconds, and uses almost no CPU time). This patch preserves the failure count across resets.

2006-05-03[PATCH] powerpc/pseries: avoid crash in PCI code if mem system not upLinas Vepstas1-0/+8
The powerpc code is currently performing PCI setup before memory initialization. PCI setup touches PCI config space registers. If the PCI card is bad, this will evoke an error, which currrently can't be handled, as the PCI error recovery code expects kmalloc() to be functional. This patch will cause the system to punt instead of crashing with cpu 0x0: Vector: 300 (Data Access) at [c0000000004434d0] pc: c0000000000c06b4: .kmem_cache_alloc+0x8c/0xf4 lr: c00000000004ad6c: .eeh_send_failure_event+0x48/0xfc This patch will also print name of the offending pci device.

2006-05-01[PATCH] spufs: fix for CONFIG_NUMAJoel H Schopp3-88/+65
Based on an older patch from Mike Kravetz <kravetz@us.ibm.com> We need to have a mem_map for high addresses in order to make fops->no_page work on spufs mem and register files. So far, we have used the memory_present() function during early bootup, but that did not work when CONFIG_NUMA was enabled. We now use the __add_pages() function to add the mem_map when loading the spufs module, which is a lot nicer.
