A23/A33 has a NAND controller which can now be used properly. Add a device node for it. The DMA function cannot work because of changed DMA IP block, so it's temporarily removed in the device node. However, with PIO mode it can still work. Tested on an Aoson M751s tablet with Boris Brezillon's "mtd: nand: allow vendor specific detection/initialization" patchset, which is needed for the large-block MLC chip to be recognized correctly.

Add a dts file for tablets using the generic inet-q972 PCB. Tablets with this PCB feature a mini-hdmi output, micro-usb usb-host, micro-usb usb-otg, 3.5mm headphone jack, a micro sd slot, (mini) power-barrel and an usb wifi module.

The dma-mapping core and the implementations do not change the DMA attributes passed by pointer. Thus the pointer can point to const data. However the attributes do not have to be a bitfield. Instead unsigned long will do fine: 1. This is just simpler. Both in terms of reading the code and setting attributes. Instead of initializing local attributes on the stack and passing pointer to it to dma_set_attr(), just set the bits. 2. It brings safeness and checking for const correctness because the attributes are passed by value. Semantic patches for this change (at least most of them): virtual patch virtual context @r@ identifier f, attrs; @@ f(..., - struct dma_attrs *attrs + unsigned long attrs , ...) { ... } @@ identifier r.f; @@ f(..., - NULL + 0 ) and // Options: --all-includes virtual patch virtual context @r@ identifier f, attrs; type t; @@ t f(..., struct dma_attrs *attrs); @@ identifier r.f; @@ f(..., - NULL + 0 ) Link: http://lkml.kernel.org/r/1468399300-5399-2-git-send-email-k.kozlowski@samsung.com Signed-off-by:

This updates the generic and arch specific implementation to return true if we need to do a tlb flush. That means if a __tlb_remove_page indicate a flush is needed, the page we try to remove need to be tracked and added again after the flush. We need to track it because we have already update the pte to none and we can't just loop back. This change is done to enable us to do a tlb_flush when we try to flush a range that consists of different page sizes. For architectures like ppc64, we can do a range based tlb flush and we need to track page size for that. When we try to remove a huge page, we will force a tlb flush and starts a new mmu gather.

__GFP_REPEAT has a rather weak semantic but since it has been introduced around 2.6.12 it has been ignored for low order allocations. PGALLOC_GFP uses __GFP_REPEAT but none of the allocation which uses this flag is for more than order-2. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests.

HYPERVISOR_vcpu_op() passes Linux's idea of vCPU id as a parameter while Xen's idea is expected. In some cases these ideas diverge so we need to do remapping. Convert all callers of HYPERVISOR_vcpu_op() to use xen_vcpu_nr(). Leave xen_fill_possible_map() and xen_filter_cpu_maps() intact as they're only being called by PV guests before perpu areas are initialized. While the issue could be solved by switching to early_percpu for xen_vcpu_id I think it's not worth it: PV guests will probably never get to the point where their idea of vCPU id diverges from Xen's.

It may happen that Xen's and Linux's ideas of vCPU id diverge. In particular, when we crash on a secondary vCPU we may want to do kdump and unlike plain kexec where we do migrate_to_reboot_cpu() we try booting on the vCPU which crashed. This doesn't work very well for PVHVM guests as we have a number of hypercalls where we pass vCPU id as a parameter. These hypercalls either fail or do something unexpected. To solve the issue introduce percpu xen_vcpu_id mapping. ARM and PV guests get direct mapping for now. Boot CPU for PVHVM guest gets its id from CPUID. With secondary CPUs it is a bit more trickier. Currently, we initialize IPI vectors before these CPUs boot so we can't use CPUID. Use ACPI ids from MADT instead. Signed-off-by:

Replace the non-standard vendor prefix stm with st for STMicroelectronics. The drivers do not specify the vendor prefixes since the I2C Core strips them away from the DT provided compatible string. Therefore, changing existing device trees does not have any impact on device detection. Signed-off-by:

This patch adds compilation and link against irqchip. Main motivation behind using irqchip code is to enable MSI routing code. In the future irqchip routing may also be useful when targeting multiple irqchips. Routing standard callbacks now are implemented in vgic-irqfd: - kvm_set_routing_entry - kvm_set_irq - kvm_set_msi They only are supported with new_vgic code. Both HAVE_KVM_IRQCHIP and HAVE_KVM_IRQ_ROUTING are defined. KVM_CAP_IRQ_ROUTING is advertised and KVM_SET_GSI_ROUTING is allowed. So from now on IRQCHIP routing is enabled and a routing table entry must exist for irqfd injection to succeed for a given SPI. This patch builds a default flat irqchip routing table (gsi=irqchip.pin) covering all the VGIC SPI indexes. This routing table is overwritten by the first first user-space call to KVM_SET_GSI_ROUTING ioctl. MSI routing setup is not yet allowed. Signed-off-by:
