b6a7e1ecef [IA64] Allow simulator to use bigger disks
The simscsi code at present overflows an int if it's given a large
disk image.  The attached patch increases the possible size to 128G.
While it's unlikely that anyone will want to use SKI with such a
large drive, the same framework is currently being used for various
virtualisation experiments.

83a78d9ba7 [IA64] Fix simscsi for new SCSI midlayer
The sd driver now uses scsi_execute_req() for almost everything.
scsi_execute_req() converts requests into scatterlists.

Fix the HP SCSI disk simulator to understand scatterlists for
more commands.

Without this patch the current kernel will not boot on the simulator
(the disks are always detected as having no sectors, and so cannot be
mounted).

0b9afede3d [IA64] more robust zx1/sx1000 machvec support
Machine vector selection has always been a bit of a hack given how
early in system boot it needs to be done.  Services like ACPI namespace
are not available and there are non-trivial problems to moving them to
early boot.  However, there's no reason we can't change to a different
machvec later in boot when the services we need are available.  By
adding a entry point for later initialization of the swiotlb, we can add
an error path for the hpzx1 machevec initialization and fall back to the
DIG machine vector if IOMMU hardware isn't found in the system.  Since
ia64 uses 4GB for zone DMA (no ISA support), it's trivial to allocate a
contiguous range from the slab for bounce buffer usage.

a4cce10492 [IA64] Fix simulator boot (for real this time).
Thanks to Stephane, we've now worked out the real cause of the
`Linux  will not boot on simulator' problem.  Turns out it's a stack
overflow because the stack pointer wasn't being initialised properly
in boot_head.S (it was being initialised to the lowest instead of the
highest address of the stack, so the first push started to overwrite
data in the BSS).

4aec0fb122 [IA64] Simulator bootloader fails with gcc 4
After building a fresh tree with gcc 4 I can't boot the simulator as
the bootloader loader dies with 

loading /home/ianw/kerntest/kerncomp//build/sim_defconfig/vmlinux...
failed to read phdr

After some investigation I believe this is do with differences between
the alignment of variables on the stack between gcc 3 and 4 and the
ski simulator.  If you trace through with the simulator you can see
that the disk_stat structure value returned from the SSC_WAIT_COMPLETION
call seems to be only half loaded.  I guess it doesn't like the alignment
of the input.

3b5cc09033 [IA64] assign_irq_vector() should not panic
Current assign_irq_vector() will panic if interrupt vectors is running
out. But I think how to handle the case of lack of interrupt vectors
should be handled by the caller of this function. For example, some
PCI devices can raise the interrupt signal via both MSI and I/O
APIC. So even if the driver for these device fails to allocate a
vector for MSI, the driver still has a chance to use I/O APIC based
interrupt. But currently there is no chance for these driver to use
I/O APIC based interrupt because kernel will panic when
assign_irq_vector() fails to allocate interrupt vector.

The following patch changes assign_irq_vector() for ia64 to return
-ENOSPC on error instead of panic (as i386 and x86_64 versions do).

  +IOC: sx2000 0.1 HPA 0xf8020002000 IOVA space 1024Mb at 0x40000000

We used to create fake PCI devices for these chips, but we no longer do that.

5f6602a101 [IA64] sba_iommu bug fixes
This fixes a couple of bugs in the zx1/sx1000 sba_iommu.  These are
all pretty low likelihood of hitting.  The first problem is a simple off
by one, deep in the sba_alloc_range() error path.  Surrounding that was
a lock ordering problem that could have potentially deadlocked with the
order the locks are grabbed in sba_unmap_single().  I moved the resource
locking into sba_search_bitmap() to prevent this.  Finally, there's a
potential race between unmapping pdir entries and marking incoming DMA
pages clean.  If you see any oddities, please let me know, but I've
tested it pretty thoroughly here.  Tony, please apply.  Thanks,

BTW, many of the options in this driver not on by default are becoming
more and more broken.  I'll be working on some patches to clean them
out, but I wanted to get this bug fix out first.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
