      ARM: 8253/1: mm: use phys_addr_t type in map_lowmem() for kernel mem region · ac084688
      Grygorii Strashko authored
      Now local variables kernel_x_start and kernel_x_end defined using
      'unsigned long' type which is wrong because they represent physical
      memory range and will be calculated wrongly if LPAE is enabled.
      As result, all following code in map_lowmem() will not work correctly.
      For example, Keystone 2 boot is broken because
       kernel_x_start == 0x0000 0000
       kernel_x_end   == 0x0080 0000
      instead of
       kernel_x_start == 0x0000 0008 0000 0000
       kernel_x_end   == 0x0000 0008 0080 0000
      and as result whole low memory will be mapped with MT_MEMORY_RW
      permissions by code (start > kernel_x_end):
      		} else if (start >= kernel_x_end) {
      			map.pfn = __phys_to_pfn(start);
      			map.virtual = __phys_to_virt(start);
      			map.length = end - start;
      			map.type = MT_MEMORY_RW;
      Hence, fix it by using phys_addr_t type for variables kernel_x_start
      and kernel_x_end.

      ARM: 8249/1: mm: dump: don't skip regions · cca547e9
      Mark Rutland authored
      Currently the arm page table dumping code starts dumping page tables
      from USER_PGTABLES_CEILING. This is unnecessary for skipping any entries
      related to userspace as the swapper_pg_dir does not contain such
      entries, and results in a couple of unfortuante side effects.
      Firstly, any kernel mappings which might exist below
      USER_PGTABLES_CEILING will not be accounted in the dump output. This
      masks any entries erroneously created below this address.
      Secondly, if the final page table entry walked is part of a valid
      mapping the page table dumping code will not log the region this entry
      is part of, as the final note_page call in walk_pgd will trigger an
      early return when 0 < USER_PGTABLES_CEILING. Luckily this isn't seen on
      contemporary systems as they typically don't have enough RAM to extend
      the linear mapping right to the end of the address space.
      Due to the way addr is constructed in the walk_* functions, it can never
      be less than USER_PGTABLES_CEILING when walking the page tables, so it
      is not necessary to avoid dereferencing invalid table addresses. The
      existing checks for st->current_prot and st->marker[1].start_address are
      sufficient to ensure we will not print and/or dereference garbage when
      trying to log information.
      This patch removes both problematic uses of USER_PGTABLES_CEILING from
      the arm page table dumping code, preventing both of these issues. We
      will now report any low mappings, and the final note_page call will not
      return early, ensuring all regions are logged.

       "kernel: Provide READ_ONCE and ASSIGN_ONCE
        As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com
        ACCESS_ONCE might fail with specific compilers for non-scalar
        Here is a set of patches to tackle that problem.
        The first patch introduce READ_ONCE and ASSIGN_ONCE.  If the data
        structure is larger than the machine word size memcpy is used and a
        warning is emitted.  The next patches fix up several in-tree users of
        ACCESS_ONCE on non-scalar types.
        This does not yet contain a patch that forces ACCESS_ONCE to work only
        on scalar types.  This is targetted for the next merge window as Linux
        next already contains new offenders regarding ACCESS_ONCE vs.
        non-scalar types"

      Move pinmux alloc/dealloc code into functions that don't take
      the spinlock so we can use from code that has the spinlock already.
      CRISv32 has no working SMP, so spinlocks becomes a NOP,
      so deadlock was never seen.

      CRIS: Export missing function symbols · dbd3c7e1
      Jesper Nilsson authored
      strcmp was lost when all other string functions were removed,
      but we still have an optimized version for this on CRISv32,
      so any driver built as a module would not have access to this symbol.
      In a similar manner, we had optimized versions of
      csum_partial_copy_from_user and __do_clear_user
      but no exported symbols for them, breaking bunch of other drivers
      when built as a module.
      At the same time, move EXPORT_SYMBOL(__copy_user) and
      EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's
      located together with the function definition.

      Pull x86 apic updates from Thomas Gleixner:
       "After stopping the full x86/apic branch, I took some time to go
        through the first block of patches again, which are mostly cleanups
        and preparatory work for the irqdomain conversion and ioapic hotplug
        Unfortunaly one of the real problematic commits was right at the
        beginning, so I rebased this portion of the pending patches without
        the offenders.
        It would be great to get this into 3.19.  That makes reworking the
        problematic parts simpler.  The usual tip testing did not unearth any
        issues and it is fully bisectible now.
        I'm pretty confident that this wont affect the calmness of the xmas
         - Split the convoluted io_apic.c code into domain specific parts
           (vector, ioapic, msi, htirq)
         - Introduce proper helper functions to retrieve irq specific data
           instead of open coded dereferencing of pointers
         - Preparatory work for ioapic hotplug and irqdomain conversion
         - Removal of the non functional pci-ioapic driver
         - Removal of unused irq entry stubs
         - Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC
           allocations for everything which is called from there.
         - Small cleanups and fixes"
