Identify CPC9x5 PCI Express, AGP, and HT host bridges using device_type and compatible properties, which is a more flexible method than using the name property (which can differ between firmwares and models).

2007-01-24[POWERPC] Do not write virq back to PCI config spaceMichal Ostrowski
- Drivers will not rely on the PCI config space value, as they've already been conditioned to rely on the irq field in "struct pci_dev". - The virq value may not be < 256 as it has been remapped. - The PCI config space should reflect the hardware configuration, which is not being changed. We are only creating a virtual irq mapping that exists in the kernel only. One would never expect the PCI hardware to generate the "virq" interrupt.

2007-01-22[PATCH] x86: fix PDA variables to work during bootJames Bottomley
The current PDA code, which went in in post 2.6.19 has a flaw in that it doesn't correctly cycle the GDT and %GS segment through the boot PDA, the CPU PDA and finally the per-cpu PDA. The bug generally doesn't show up if the boot CPU id is zero, but everything falls apart for a non zero boot CPU id. The basically kills voyager which is perfectly capable of doing non zero CPU id boots, so voyager currently won't boot without this. The fix is to be careful and actually do the GDT setups correctly.

2007-01-22[POWERPC] Fix broken DMA on non-LPAR pSeriesLinas Vepstas
It appears that the iommu table address is never stored, and thus never found, on non-lpar systems. Thus, for example, during boot: <7>[ 93.067916] PCI: Scanning bus 0001:41 <7>[ 93.068542] PCI: Found 0001:41:01.0 [8086/100f] 000200 00 <7>[ 93.068550] PCI: Calling quirk c0000000007822e0 for 0001:41:01.0 <7>[ 93.069815] PCI: Fixups for bus 0001:41 <4>[ 93.070167] iommu: Device 0001:41:01.0 has no iommu table <7>[ 93.070251] PCI: Bus scan for 0001:41 returning with max=41 No iommu table? How can that be? Well, circa line 471 of arch/powerpc/platforms/pseries/iommu.c we see the code: while (dn && PCI_DN(dn) && PCI_DN(dn)->iommu_table == NULL) dn = dn->parent; and a few lines later is the surprising print statement about the missing table. Seems that this loop ran unto the end, never once finding a non-null PCI_DN(dn)->iommu_table. The problem can be found a few lines earlier: it sems that the value of PCI_DN(dn)->iommu_table is never ever set. Thus, the patch sets it. The patch was tested on a Power4 system running in full system partition mode, which is where I saw the problem. It works; I've not done any wider testing. Had a brief discussion on this on irc.

Since __cpuinit would map to __init with this kind of a configuration, we get a .text refering .init.data warning. This patch solves the problem by converting all of __cpu_up, _cpu_up and cpu_up from __devinit to __cpuinit. The approach is justified since the callers of cpu_up are either dependent on CONFIG_HOTPLUG_CPU or are of __init type. Thus when CONFIG_HOTPLUG_CPU=y, all these cpu up functions would land up in .text section, and when CONFIG_HOTPLUG_CPU=n, all these functions would land up in .init section.

2007-01-11[PATCH] x86-64: - Ignore long SMI interrupts in clock calibrationJack Steiner
Ensure that no SMI interrupts occur between the read of the HPET & TSC in the clock calibration loop. I noticed that a 2.66GHz system incorrectly detected the processor clock speed about 1/7 of the time: time.c: Detected 2660.005 MHz processor. (most of the time) time.c: Detected 2988.203 MHz processor. (sometime) The problem is caused by an SMI interrupt occuring in hpet_calibrate_tsc() between the read of the HPET & TSC. Prior to switching the BIOS into ACPI mode, it appears that every 27msec an SMI interrupt occurs. The SMI interrupt takes 4.8 msec to process. Note: On my test system, TICK_MIN had to be >380. I picked 5000 to minimize risk of having a value that is too small for other platforms.

Anyway this function is really small so not freeing this memory after init is not a big deal. Secondly, from a programming perspective, probably genapic should not provide pointers to functions which have been freed as genapic is non __init and is used even after initialization is complete.

2007-01-11[PATCH] i386: cpu hotplug/smpboot misc MODPOST warning fixesVivek Goyal
o Misc smpboot/cpu hotplug path cleanups. I did those to supress the warnings generated by MODPOST. These warnings are visible only if CONFIG_RELOCATABLE=y. o CONFIG_RELOCATABLE compiles the kernel with --emit-relocs option. This option retains relocation information in vmlinux file and MODPOST is quick to spit out "Section mismatch" warnings. o This patch fixes some of those warnings. Many of the functions in smpboot case are __devinit type and they in turn accesses text/data which if of type __cpuinit. Now if CONFIG_HOTPLUG=y and CONFIG_HOTPLUG_CPU=n then we end up in cases where a function in .text segment is calling another function in .init.text segment and MODPOST emits warning.

This should have meant broken CPU hotplug.

2007-01-10 [MIPS] Alchemy: Fix PCI-memory accessAlexander Bigga
The problem was introduced in 2.6.18.3 with the casting of some 36bit-defines (PCI memory) in au1000.h to resource_size_t which may be u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT. With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed because the ioremap in arch/mips/au1000/common/pci.c already used the truncated addresses. With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c fails because the maximum iomem-address is 0xffffffff (32bit) but the pci-memory-start-address is 0x440000000 (36bit). To get pci working again, I propose the following patch: 1. remove the resource_size_t-casting from au1000.h again 2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and necessary here. The 36bit-handling will be done in __fixup_bigphys_addr). With this patch pci works again like in 2.6.18.2, the gcc-compile warnings in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

2007-01-10[MIPS] Fix N32 SysV IPC routinesAtsushi Nemoto
Add wrappers for N32 msg{snd,rcv}. compat_sys_msg{snd,rcv} can not not be used as system call entries as is. This fix is based on Kaz Kylheku's patch. Also change a type of last argument of sysn32_semctl to match its true size. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-01-09[S390] don't call handle_mm_fault() if in an atomic context.Heiko Carstens
There are several places in the futex code where a spin_lock is held and still uaccesses happen. Deadlocks are avoided by increasing the preempt count. The pagefault handler will then not take any locks but will immediately search the fixup tables.

2007-01-09[S390] Fix vmalloc area size calculation.Heiko Carstens
setup_memory_end() uses VMALLOC_END instead of VMALLOC_END_INIT to calculate the maximum supported size of physical memory. Since VMALLOC_END is zero, this will cause a crash on 31 bit systems.

2007-01-09[S390] Fix cpu hotplug (missing 'online' attribute).Heiko Carstens
72486f1f8f0a2bc828b9d30cf4690cf2dd6807fc inverts the logic if an 'online' attribute in /sys/devices/system/cpu/cpuX should appear. So we end up with no hotpluggable cpus at all... Set the hotpluggable value to one to make sure the online attribute appears again. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
