      ARM: 8304/1: Respect NO_KERNEL_MAPPING when we don't have an IOMMU · 6e8266e3
      Carlo Caione authored
      Even without an iommu, NO_KERNEL_MAPPING is still convenient to save on
      kernel address space in places where we don't need a kernel mapping.
      Implement support for it in the two places where we're creating an
      expensive mapping.
      
      __alloc_from_pool uses an internal pool from which we already have
      virtual addresses, so it's not relevant, and __alloc_simple_buffer uses
      alloc_pages, which will always return a lowmem page, which is already
      mapped into kernel space, so we can't prevent a mapping for it in that
      case.

      ARM: 8293/1: kernel: fix pci_mmap_page_range() offset calculation · 415ae101
      Lorenzo Pieralisi authored
      The pci_mmap_page_range() API should be written to expect offset
      values representing PCI memory resource addresses as seen by user
      space, through the pci_resource_to_user() API.
      
      ARM relies on the standard implementation of pci_resource_to_user()
      which actually is an identity map and exports to user space
      PCI memory resources as they are stored in PCI devices resources
      structures, which represent CPU physical addresses (fixed-up using
      BUS to CPU address conversions) not PCI bus addresses.
      
      Therefore, on ARM platforms where the mapping between CPU and BUS
      address is not a 1:1 the current pci_mmap_page_range() implementation is
      erroneous, in that an additional shift is applied to an already fixed-up
      offset passed from userspace.
      
      Hence, this patch removes the mem_offset from the pgoff calculation
      since the offset as passed from user space already represents the CPU
      physical address corresponding to the resource to be mapped, ie no
      additional offset should be applied.

      ARM: 8219/1: handle interworking and out-of-range relocations separately · 2b8514d0
      Ard Biesheuvel authored
      Currently, interworking calls on module boundaries are not supported,
      and are handled by the same error handling code path as non-interworking
      calls whose targets are simply out of range.
      
      Before modifying the handling of those out-of-range jump and call
      relocations in a subsequent patch, move the handling of interworking
      restrictions out of it.

      Linux 4.0-rc1 · c517d838
      Linus Torvalds authored
      .. after extensive statistical analysis of my G+ polling, I've come to
      the inescapable conclusion that internet polls are bad.
      
      Big surprise.
      
      But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38%
      margin, in a poll that people weren't even supposed to participate in.
      Who can argue with solid numbers like that? 5,796 votes from people who
      can't even follow the most basic directions?
      
      In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%,
      but with a total of 29,110 votes right now.
      
      Now, arguably, that vote spread is only about 3,200 votes, which is less
      than the almost six thousand votes that the "please ignore" poll got, so
      it could be considered noise.
      
      But hey, I asked, so I'll honor the votes.
