This patch removes all occurances of _INLINE_ in the kernel.
With the exception of tty_flip.h, I've simply removed the inline's since
gcc should know best which functions to be inlined.

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.

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).

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).

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.

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).

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!
