      [PATCH] ppc64: add useful warning message in hugepage code · 8d507e4e
      Andrew Morton authored
      From: David Gibson <david@gibson.dropbear.id.au>
      
      This patch adds a debugging message to the ppc64 hugepage code when we
      attempt to open the "low" (32-bit) hugepage window on PPC64, but can't
      because a (non-hugepage) mapping already exists in the region.

      [PATCH] ppc64: allow MAP_FIXED hugepage mappings · e9acfc13
      Andrew Morton authored
      From: David Gibson <david@gibson.dropbear.id.au>
      
      On PowerPC64 the "low" hugepage range (at 2-3G for use by 32-bit processes)
      needs to be activated before it can be used.  hugetlb_get_unmapped_area()
      automatically activates the range for hugepage mappings in 32-bit processes
      which are not MAP_FIXED.  However for MAP_FIXED mmap()s, even at a suitable
      address will fail if the region is not already activated, because there is
      no suitable callback from the generic MAP_FIXED code path into the arch
      code.
      
      This patch corrects this problem and allows PPC64 to do MAP_FIXED hugepage
      mappings in the low hugepage range.

      [PATCH] ppc64: bugfix for hugepage support · ccfcbaed
      Andrew Morton authored
      From: David Gibson <david@gibson.dropbear.id.au>
      
      Due to a misunderstanding of pmd_offset() the PPC64 hugepage code could end
      up looking at bogus pages as if they were PMD pages.

      [PATCH] ppc64: create dma_mapping_error · 007658d4
      Andrew Morton authored

      This creates DMA_ERROR_CODE and uses it everywhere instead of
      PCI_DMA_ERROR_CODE as we really want the three DMA mapping API's to return
      a single error code.  Also we now have dma_mapping_error and
      vio_dma_mapping_error - and this latter and pci_dma_mapping_error both just
      call the former.
      
      Also a small fix in the vscsi - dma_map_sg returns 0 to indicate an error.
