* kexec: support kexec/kdump on EFI systemsVivek Goyal2014-08-091-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does two things. It passes EFI run time mappings to second kernel in bootparams efi_info. Second kernel parse this info and create new mappings in second kernel. That means mappings in first and second kernel will be same. This paves the way to enable EFI in kexec kernel. This patch also prepares and passes EFI setup data through bootparams. This contains bunch of information about various tables and their addresses. These information gathering and passing has been written along the lines of what current kexec-tools is doing to make kexec work with UEFI.

* drivers/net/ethernet/amd/pcnet32.c: neaten and remove unnecessary OOM messagesJoe Perches2014-08-091-25/+18
| | | | | | | | | | | | | | | | | Make the code flow a little better for 80 columns. Use a consistent style for the RX and TX rings allocation. Use BIT macro. Use a temporary unsiged int entries for (1<<size). Remove the OOM messages as they duplicate the generic OOM and dump_stack() provided by the memory subsystem. Reflow allocs to 80 columns.

* rapidio/tsi721_dma: rework scatter-gather list handlingAlexandre Bounine2014-08-092-352/+378
| | | | | | | | | | | | | | | | | | | | | | | | | | Rework Tsi721 RapidIO DMA engine support to allow handling data scatter/gather lists longer than number of hardware buffer descriptors in the DMA channel's descriptor list. The current implementation of Tsi721 DMA transfers requires that number of entries in a scatter/gather list provided by a caller of dmaengine_prep_rio_sg() should not exceed number of allocated hardware buffer descriptors. This patch removes the limitation by processing long scatter/gather lists by sections that can be transferred using hardware descriptor ring of configured size. It also introduces a module parameter "dma_desc_per_channel" to allow run-time configuration of Tsi721 hardware buffer descriptor rings.

| | | | | | | | | | | | | | | | | | | | In particular seeing zero in eft->month is problematic, as it results in -1 (converted to unsigned int, i.e. yielding 0xffffffff) getting passed to rtc_year_days(), where the value gets used as an array index (normally resulting in a crash). This was observed with the driver enabled on x86 on some Fujitsu system (with possibly not up to date firmware, but anyway). Perhaps efi_read_alarm() should not fail if neither enabled nor pending are set, but the returned time is invalid?

This gets rid of a ton of old cruft that has been bitrotting in a long while. It was broken for quite a few versions already and nobody noticed. Nobody uses those machines anymore. While at it, he cleaned up a bunch of old dusty cabinets, getting rid of a skeletton or two. Then, we have some base VFIO support for KVM, which allows assigning of PCI devices to KVM guests, support for large 64-bit BARs on "powernv" platforms, support for HMI (Hardware Management Interrupts) on those same platforms, some sparse-vmemmap improvements (for memory hotplug), There is the usual batch of Freescale embedded updates (summary in the merge commit) and fixes here or there, I think that's it for the highlights" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (102 commits) powerpc/eeh: Export eeh_iommu_group_to_pe() powerpc/eeh: Add missing #ifdef CONFIG_IOMMU_API powerpc: Reduce scariness of interrupt frames in stack traces powerpc: start loop at section start of start in vmemmap_populated() powerpc: implement vmemmap_free() powerpc: implement vmemmap_remove_mapping() for BOOK3S powerpc: implement vmemmap_list_free() powerpc: Fail remap_4k_pfn() if PFN doesn't fit inside PTE powerpc/book3s: Fix endianess issue for HMI handling on napping cpus. powerpc/book3s: handle HMIs for cpus in nap mode. powerpc/powernv: Invoke opal call to handle hmi. powerpc/book3s: Add basic infrastructure to handle HMI in Linux. powerpc/iommu: Fix comments with it_page_shift powerpc/powernv: Handle compound PE in config accessors powerpc/powernv: Handle compound PE for EEH powerpc/powernv: Handle compound PE powerpc/powernv: Split ioda_eeh_get_state() powerpc/powernv: Allow to freeze PE powerpc/powernv: Enable M64 aperatus for PHB3 powerpc/eeh: Aux PE data for error log ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Cpufreq depends on platform firmware to implement PStates. In case of platform firmware failure, cpufreq should not panic host kernel with BUG_ON(). Less severe pr_warn() will suffice. Add firmware_has_feature(FW_FEATURE_OPALv3) check to skip probing for device-tree on non-powernv platforms. Signed-off-by: Vaidyanathan Srinivasan <svaidy@linux.vnet.ibm.com> Acked-by: Gautham R.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CoreNet Coherency Fabric is part of the memory subsystem on some Freescale QorIQ chips. It can report coherency violations (e.g. due to misusing memory that is mapped noncoherent) as well as transactions that do not hit any local access window, or which hit a local access window with an invalid target ID.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver doesn't build, and apparently has not built since arch/ppc was removed in 2008 (when mk_int_int_mask was removed from asm/irq.h, among other build errors). A few weeks ago I asked whether anyone was actively maintaining this code, and got no positive response: http://patchwork.ozlabs.org/patch/352082/ So, let's remove it.
