      devicetree: bindings: add Zarlink to the vendor prefixes · e8640b79
      Valentin Longchamp authored
      Even though the company belongs to Microsemi, many chips are still
      labeled as Zarlink. Among them is the family of network clock generators,
      the zl3034x.

      powerpc/fsl-booke64: Set vmemmap_psize to 4K · e57eeae4
      Scott Wood authored
      The only way Freescale booke chips support mappings larger than 4K
      is via TLB1.  The only way we support (direct) TLB1 entries is via
      hugetlb, which is not what map_kernel_page() does when given a large
      page size.
      
      Without this, a kernel with CONFIG_SPARSEMEM_VMEMMAP enabled crashes on
      boot with messages such as:
      
      PID hash table entries: 4096 (order: 3, 32768 bytes)

      powerpc/fsl-rio: Fix fsl_rio_setup error paths and use-after-unmap · a614db9a
      Scott Wood authored
      Several of the error paths from fsl_rio_setup are missing error
      messages.
      
      Worse, fsl_rio_setup initializes several global pointers and does not
      NULL them out after freeing/unmapping on error.  This caused
      fsl_rio_mcheck_exception() to crash when accessing rio_regs_win which
      was non-NULL but had been unmapped.

      Liu Gang, are you sure all of these error conditions are fatal?  Why
      does the rio driver fail if rmu is not present (e.g.  on t4240)?
