2006-10-16[POWERPC] Check for offline nodes in pci NUMA codeAnton Blanchard
During boot we bring up all memory and cpu nodes. Normally a PCI device will be in one of these online nodes, however in some weird setups it may not. We have only seen this in the lab but we may as well check for the case and fallback to -1 (all nodes).

2006-10-16[POWERPC] Never panic when taking altivec exceptions from userspaceAnton Blanchard
At the moment we rely on a cpu feature bit or a firmware property to detect altivec. If we dont have either of these and the cpu does in fact support altivec we can cause a panic from userspace. It seems safer to always send a signal if we manage to get an 0xf20 exception from userspace. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

The default configuration file for the MPC8349E-mITX reference board, mpc834x_itx_defconfig, did not include support for DOS partition table types.

2006-10-15[PATCH] make UML compile (FC6/x86-64)Ulrich Drepper
I need this patch to get a UML kernel to compile. This is with the kernel headers in FC6 which are automatically generated from the kernel tree. Some headers are missing but those files don't need them. At least it appears so since the resuling kernel works fine. Tested on x86-64.

2006-10-14ACPI: SCI interrupt source overrideKimball Murray
The Linux group at Stratus Technologies has come across an issue with SCI routing under ACPI. We were bitten by this when we made an x86_64 platform whose BIOS provides an Interrupt Source Override for the SCI itself. Apparently the override has no effect for the System Control Interrupt, and this appears to be because of the way the SCI is setup in the ACPI code. It does not handle the case where busirq != gsi. The code that sets up the SCI routing assumes that bus irq == global irq. So there is simply no provision for telling it otherwise. The attached patch provides this mechanism. This patch provided by David Bulkow, was tested on an i386 platform, which does not use the SCI override, and also on an x86_64 platform which does use an override.

2006-10-14ACPI: Processor native C-states using MWAITVenkatesh Pallipadi
Intel processors starting with the Core Duo support support processor native C-state using the MWAIT instruction. Refer: Intel Architecture Software Developer's Manual http://www.intel.com/design/Pentium4/manuals/253668.htm Platform firmware exports the support for Native C-state to OS using ACPI _PDC and _CST methods. Refer: Intel Processor Vendor-Specific ACPI: Interface Specification http://www.intel.com/technology/iapc/acpi/downloads/302223.htm With Processor Native C-state, we use 'MWAIT' instruction on the processor to enter different C-states (C1, C2, C3). We won't use the special IO ports to enter C-state and no SMM mode etc required to enter C-state. Overall this will mean better C-state support. One major advantage of using MWAIT for all C-states is, with this and "treat interrupt as break event" feature of MWAIT, we can now get accurate timing for the time spent in C1, C2, .. states.

However, sparc vmlinux has plenty of relocatable sections because it is being built with 'ld -r' (to allow for btfixup processing). So for sparc, modpost does do a lot of checking. Sure enough, running modpost on arch/sparc/boot/image yields no output (i.e. all is well). modpost.c check_sec_ref() has: /* We want to process only relocation sections and not .init */ if (sechdrs[i].sh_type == SHT_RELA) { // check here } else if (sechdrs[i].sh_type == SHT_REL) { // check here } Signed-off-by: Martin Habets <errandir_news@mph.eclipse.co.uk> Signed-off-by: David S.

2006-10-12sh: interrupt exception handling reworkPaul Mundt
Kill off interrupt_table for all of the CPU subtypes, we now default in to stepping in to do_IRQ() for _all_ IRQ exceptions and counting the spurious ones, rather than simply flipping on the ones we cared about. This and enabling the IRQ by default automatically has already uncovered a couple of bugs and IRQs that weren't being caught, as well as some that are being generated far too often (SCI Tx Data Empty, for example). The general rationale is to use a marker for interrupt exceptions, test for it in the handle_exception() path, and skip out to do_IRQ() if it's found. Everything else follows the same behaviour of finding the cached EXPEVT value in r2/r2_bank, we just rip out the INTEVT read from entry.S entirely (except for in the kGDB NMI case, which is another matter). Note that while this changes the do_IRQ() semantics regarding r4 handling, they were fundamentally broken anyways (relying entirely on r2_bank for the cached code). With this, we do the INTEVT read from do_IRQ() itself (in the CONFIG_CPU_HAS_INTEVT case), or fall back on r4 for the muxed IRQ number, which should also be closer to what SH-2 and SH-2A want anyways.
