This patch removes some redundant code in the function setup_sigcontext().
The registers ar.ccv,b7,r14,ar.csd,ar.ssd,r2-r3 and r16-r31 are not restored
in restore_sigcontext() when (flags & IA64_SC_FLAG_IN_SYSCALL) is true.

This patch makes swiotlb not allocate a memory area spanning LLD's

This is the latter half of my iommu work to make the IOMMUs respect
LLDs restrictions.
IOMMUs allocate memory areas without considering a low level driver's
segment boundary limits. So we have some workarounds: splitting sg

This adds new accessors for segment_boundary_mask in
device_dma_parameters structure in the same way I did for
max_segment_size. So we can easily change where to place struct
device_dma_parameters in the future.
dma_get_segment boundary returns 0x if dma_parms in struct
device isn't set up
This is a one-line patch to add the following to __scsi_alloc_queue():
dma_set_seg_boundary(dev, shost->dma_boundary);
This is the simplest approach but the result looks odd,
__scsi_alloc_queue() does:
blk_queue_segment_boundary(q, shost->dma_boundary);
dma_set_seg_boundary(dev, shost->dma_bound
This adds PCI's accessor for segment_boundary_mask in
device_dma_parameters.
The default segment_boundary is set to 0x, same to the block
layer's default value (and the scsi mid layer uses the same value).

When pdflush is writing back inodes, it can get stuck on inode cluster

Change all async metadata buffers to use [READ|WRITE]_META I/O types

This renames arch/x86/ia32/tls32.c to arch/x86/kernel/tls.c, which does
nothing now but paves the way to consolidate this code for 32-bit too.

This consolidates the four different places that implemented the same
encoding magic for the GDT-slot 32-bit TLS support. The old tls32.c was
renamed and is now only slightly modified to be the shared implementation.

Yeah, sorry about that. It was late and the whole TLS thing was a sudden

It's our clever way of reducing the tester base so we don't get so many
bug reports.

percpu_modcopy is defined multiple times in arch files. However, the only
use is in module.c. Put a static definition into module.c and remove
the definitions from the arch files.

Module.c should not define linker variables on its own. We have an include
file for that.

Hi,
I have a rather nasty situation developing on one of the big 24x7
production database servers. It seems that a batch of drives in one of the
servers started to fail.
The file servers are ext3fs on a top of raid-0 over a pair of raid-1 mirrors,
with each of raid-1 mirrors having two drives.
