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.

Due to a misunderstanding of pmd_offset() the PPC64 hugepage code could end
up looking at bogus pages as if they were PMD pages.

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.

This fixes the build on non cache coherent PPC32 platforms.

People need the global wake events even when not sleeping:
they are used for lid open events at least on some laptops.
As such, they should be enabled by default.

You can disable them with "acpi_leave_gpes_disabled" if
your machine doesn't need them, and you want to get a few
less GPE's.

Spotted by Suparna: if the first range check fails, we leak a ref on the io
context.

Currently, to be able to send a reset in the FORWARD chain of iptables
for bridged traffic, ip forwarding must be enabled. This causes confusion
and in some situations people really don't want to enable ip forwarding.
The patch below lets the user send reset packets for bridged frames in
the FORWARD chain, with ip forwarding disabled (as long as there is a
route).

In the ALSA cleanup for duplicate PCI ID's, they weren't exactly
duplicated, resulting in problems in the au8810.c driver.

This fixes the problem

The last fix apparently only worked for device 0, since the driver
screwed up the port offsets (due to a wonky VIA hardware layout,
really). 

This patch fixes device 1 detection for the users still seeing problems
in -rc3.

In both uniprocessor and SMP, the fealnx driver's TX-submit path can 
race against the interrupt handler, with disastrous results.  Add the
lock that needed to be there all along, to fix this.

There's another problem in the RX path, that will be sent as a separate 
patch, as soon as we get that patch 100% nailed down, and acceptable for
a Release Candidate.
