We weren't using the recommended sequence for putting the CPU into nap mode. When I changed the idle loop, for some reason 7447A cpus started hanging when we put them into nap mode. Changing to the recommended sequence fixes that. The complexity here is that the recommended sequence is a loop that keeps putting the cpu back into nap mode. Clearly we need some way to break out of the loop when an interrupt (external interrupt, decrementer, performance monitor) occurs. Here we use a bit in the thread_info struct to indicate that we need this, and the exception entry code notices this and arranges for the exception to return to the value in the link register, thus breaking out of the loop. We use a new `local_flags' field in the thread_info which we can alter without needing to use an atomic update sequence. The PPC970 has the same recommended sequence, so we do the same thing there too. This also fixes a bug in the kernel stack overflow handling code on 32-bit, since it was causing a value that we needed in a register to get trashed. Signed-off-by: NPaul Mackerras <paulus@samba.org>

The at91_cf driver got out of sync with certain changes in the PCMCIA layer, notably getting rid of some duplication of data ... causing the version merged to kernel.org to fail compiling. This patch gives the at91_cf platform device a new iomem resource, using it so this new pcmcia scheme works. It also cleans up some whitepsace bugs that have accumulated over time (mostly too-long lines).

I use 2.6.15.6 Linux kernel and found some problems. I have about 100 Linux boxes (all with the same (binary the same) kernel). Last time I have upgraded all those boxes from 2.4.32 to 2.6.15.6 (first 2.6.15.1, next .2, .4 and .6) and I have found some problems on VIA based PC's. Probably the reason of this is that some VIA chipsets are unrecognized by IRQ router. In line 586 there is: /* FIXME: add new ones for 8233/5 */ There were only a few of chipsets ID's there, some of my VIA chipsets were not present and kernel used default IRQ router. I have added three entries, so that the code looks like: case PCI_DEVICE_ID_VIA_82C596: case PCI_DEVICE_ID_VIA_82C686: case PCI_DEVICE_ID_VIA_8231: case PCI_DEVICE_ID_VIA_8233A: case PCI_DEVICE_ID_VIA_8235: case PCI_DEVICE_ID_VIA_8237: case PCI_DEVICE_ID_VIA_8237_SATA: /* FIXME: add new ones for 8233/5 */ r->name = "VIA"; r->get = pirq_via_get; r->set = pirq_via_set; return 1; } The kernel goes fine but I haven't testes it for weeks, I'm just a moment after reboot :) One thing is different (better?): Using previus kernel I had: PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 0 now I have: PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 11 Maybe it is good idea to add there some more VIA chipsets? The ones I have added seem to be OK. From: Grzegorz Janoszka <Grzegorz@Janoszka.pl> Acked-by: NMartin Mares <mj@ucw.cz> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64. Currently all three arches compile it from arch/i386, which means that ia64 and x86_64 depend on things in arch/i386 that they wouldn't otherwise care about. This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing trailing whitespace) and the associated Makefile changes. All three architectures already set CONFIG_DMI in their top-level Kconfig files.

This patch modifies ia64's show_mem() to walk the vmem_map page tables and rapidly skip forward across regions where the page tables are missing. This prevents the pfn_valid() check from causing numerous unnecessary page faults. Without this patch on a 512 node 512 cpu system where every node has four memory holes, the show_mem() call takes 1 hour 18 minutes. With this patch, it takes less than 3 seconds.

When restoring the 'decrementer', (Step 34) decrementer seems to be adjusted with the number of cycles th= at a spu thread has not been running.

Compile the 32bit kernel with -mcpu=powerpc. This reduces the imagesize when a compiler is used that defaults to -mtune=power4. It inserts lots of nops to please the 64bit cpu instruction scheduling.

Basically an in-kernel implementation of tee, which uses splice and the pipe buffers as an intelligent way to pass data around by reference. Where the user space tee consumes the input and produces a stdout and file output, this syscall merely duplicates the data inside a pipe to another pipe. No data is copied, the output just grabs a reference to the input pipe data. Signed-off-by: NJens Axboe <axboe@suse.de>

When nolapic was passed or the local APIC was disabled for another reason ACPI would still parse the IO-APICs until these were explicitely disabled with noapic. Usually this resulted in a non booting configuration unless "nolapic noapic" was used. I also disabled the local APIC parsing in this case, although that's only cosmetic (suppresses a few printks) This hopefully makes nolapic work in all cases.

The former is not supported in x86_64 and the latter is enabled only in i386. Fix by enabling the latter method in x86_64 only if supported by the BIOS.

While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't being exported from lib/string.c. Investigating further, I noticed a changeset that removed its export and added it to _ksyms.c on a few more architectures. The justification was that "other arches do it." I think this is wrong, since no architecture currently defines __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it themselves. Therefore, consolidate the export to lib/string.c.

Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.
