      [PATCH] siginfo.si_band is long · 112347bb
      Andrew Morton authored 
      From: Marcus Meissner <meissner@suse.de>

After discussion on the glibc list the result was that=20 si_band is "long
int" according to POSIX:

	http://www.opengroup.org/onlinepubs/007904975/basedefs/signal.h.html

Ulrich Drepper refused a patch to fix glibc due to this reason:
	http://sources.redhat.com/ml/libc-alpha/2004-03/msg00254.html

so here is the patch to fix it in the kernel.

ppc64 and s390x were broken before and are fixed by this patch too.

      [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 
      From: Anton Blanchard <anton@samba.org>

From: Stephen Rothwell <sfr@canb.auug.org.au>

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.
