2007-01-26[PATCH] Fix UML on non-standard VM split hostsJeff Dike
This fixes UML on hosts with non-standard VM splits. We had changed the config variable that controls UML behavior on such hosts, but not propogated the change everywhere. In particular, the values of STUB_CODE and STUB_DATA relied on the old variable. I also reformatted the HOST_VMSPLIT_3G help to make it more standard. Spotted by uml@flonatel.org.

This patch makes x86_64 define arch_vma_name for CONFIG_IA32_EMULATION. This makes the ia32 vDSO mapping appear in /proc/PID/maps with "[vdso]" for ia32 processes, as it does on native i386.

2007-01-26[PATCH] x86_64 ia32 vDSO: use VM_ALWAYSDUMPRoland McGrath
This patch fixes ia32 core dumps on x86_64 to include just one phdr for the vDSO vma. Currently it writes a confused format with two phdrs for the address, one without contents and one with. This patch removes the special-case core writing macros for the ia32 vDSO. Instead, it uses VM_ALWAYSDUMP in the vma. This changes core dumps so they no longer include the non-PT_LOAD phdrs from the vDSO, consistent with fixed native i386 core dumps.

2007-01-26[PATCH] i386 vDSO: use VM_ALWAYSDUMPRoland McGrath
This patch fixes core dumps to include the vDSO vma, which is left out now. It removes the special-case core writing macros, which were not doing the right thing for the vDSO vma anyway. Instead, it uses VM_ALWAYSDUMP in the vma; there is no need for the fixmap page to be installed. It handles the CONFIG_COMPAT_VDSO case by making elf_core_dump use the fake vma from get_gate_vma after real vmas in the same way the /proc/PID/maps code does. This changes core dumps so they no longer include the non-PT_LOAD phdrs from the vDSO. I made the change to add them in the first place, but in turned out that nothing ever wanted them there since the advent of NT_AUXV. It's cleaner to leave them out, and just let the phdrs inside the vDSO image speak for themselves.

2007-01-26[PATCH] Fix CONFIG_COMPAT_VDSORoland McGrath
I wouldn't mind if CONFIG_COMPAT_VDSO went away entirely. But if it's there, it should work properly. Currently it's quite haphazard: both real vma and fixmap are mapped, both are put in the two different AT_* slots, sysenter returns to the vma address rather than the fixmap address, and core dumps yet are another story. This patch makes CONFIG_COMPAT_VDSO disable the real vma and use the fixmap area consistently. This makes it actually compatible with what the old vdso implementation did.

2007-01-24[ARM] 4102/1: Allow for PHYS_OFFSET on any valid 2MiB addressLinus Walleij
This patchs allows the offset to the first page of physical memory to be on any 2MB boundary whereas the previous code could only handle psysical offset to any 16MB boundary (0xNN000000) or any 1MB boundary below 0x01000000 (e.g. 0x00N00000). The problem is a consequence of the orr one-byte syntax, so we fix this and we can place the first bank of memory at 0x28e00000. I have also included an explicit check that disallow compilation when PHYS_OFFSET is not on a 2MiB boundary. head.S would be the proper place to have this at since this is the first file that attempts to use PHYS_OFFSET during compile.

Now we have more generic constants it is sensible to use those as return codes so that any function dealing with >1 GPIO does not need to do it's own number processing.

SMTC pseudo-interrupts between TCs are deferred and queued if the target TC is interrupt-inhibited (IXMT). In the first SMTC prototypes, these queued IPIs were serviced on return to user mode, or on entry into the kernel idle loop. The INSTANT_REPLAY option dispatches them as part of local_irq_restore() processing, which adds runtime overhead (hence the option to turn it off), but ensures that IPIs are handled promptly even under heavy I/O interrupt load.

2007-01-23[PATCH] Revert nmi_known_cpu() check during boot option parsingVenkatesh Pallipadi
Commit f2802e7f571c05f9a901b1f5bd144aa730ccc88e and its x86 version (b7471c6da94d30d3deadc55986cc38d1ff57f9ca) adds nmi_known_cpu() check while parsing boot options in x86_64 and i386. With that, "nmi_watchdog=2" stops working for me on Intel Core 2 CPU based system. The problem is, setup_nmi_watchdog is called while parsing the boot option and identify_cpu is not done yet. So, the return value of nmi_known_cpu() is not valid at this point. So revert that check. This should not have any adverse effect as the nmi_known_cpu() check is done again later in enable_lapic_nmi_watchdog().

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. Tested on a i386 SMP machine running linux-2.6.20-rc3-mm1.

2007-01-11[PATCH] Fix sparsemem on CellDave Hansen
Fix an oops experienced on the Cell architecture when init-time functions, early_*(), are called at runtime. It alters the call paths to make sure that the callers explicitly say whether the call is being made on behalf of a hotplug even, or happening at boot-time. It has been compile tested on ppc64, ia64, s390, i386 and x86_64.
