[PATCH] SCSI: fix request flag-related build breakage

The ->flags in struct request was split into two variables, in a recent
changeset.  The merge of this change forgot to update SCSI's libsas,
probably because libsas was a very recent merge.

[PATCH] scsi: device_reprobe() can fail

device_reprobe() should return an error code.  When it does so,
scsi_device_reprobe() should propagate it back.

[PATCH] PCI quirks update

This fixes two things

Firstly someone mistakenly used "errata" for the singular.  This causes
Dave Woodhouse to emit diagnostics whenever the string is read, and so
should be fixed.

Secondly the AMD AGP tunnel has an erratum which causes hangs if you try
and do direct PCI to AGP transfers in some cases.  We have a flag for
PCI/PCI failures but we need a different flag for this really as in this
case we don't want to stop PCI/PCI transfers using things like IOAT and the
new RAID offload work.

I'll post some updates to make proper use of the PCIAGP flag in the
media/video drivers to Mauro.

[PATCH] hot-add-mem x86_64: Kconfig changes

Create Kconfig namespace for MEMORY_HOTPLUG_RESERVE and MEMORY_HOTPLUG_SPARSE.
 This is needed to create a disticiton between the 2 paths.  Selecting the
high level opiton of MEMORY_HOTPLUG will get you MEMORY_HOTPLUG_SPARSE if you
have sparsemem enabled or MEMORY_HOTPLUG_RESERVE if you are x86_64 with
discontig and ACPI numa support.

Enable x86_64 srat.c to share code between both reserve and sparsemem based
add memory paths.  Both paths need the hot-add area node locality infomration
(nodes_add).  This code refactors the code path to allow this.

[PATCH] hot-add-mem x86_64: use CONFIG_MEMORY_HOTPLUG_RESERVE

The api for hot-add memory already has a construct for finding nodes based on
an address, memory_add_physaddr_to_nid.  This patch allows the fucntion to do
something besides return 0.  It uses the nodes_add infomation to lookup to
node info for a hot add event.
