Rename _bss to __bss_start as on other architectures. That makes it
possible to use the <linux/sections.h> instead of own declarations. Also
add __bss_stop because that symbol exists on other architectures.

With the unionfs patch applied I get
ERROR: "copy_page" [fs/unionfs/unionfs.ko] undefined!
the other architectures (some, at least) export copy_page() so I guess ia64
should also do so.
To do this we need to move the copy_page() functions out of lib.a and into
built-in.o and add the EXPORT_SYMBOL().

The sizeof a pointer is constant, we want the sizeof what is pointed to.
Zero out 'sizeof(*efi_systab)' bytes of the efi_system_table_t pointer
'efi_systab' instead.

Add a dummy nop at the end of _start() to maintain the invariant that
the return-pointer (rp) always point to the calling function. This
makes unwinding stop at the last frame, as it should.

Robert P.J. Day has a script that finds places in the code that
use non-existent CONFIG variables. It complained of two uses in
ia64 specific code: CONFIG_IA64_SDV and CONFIG_KDB (both used in
the hp/sim code).

We used to warn unless the EFI system table major revision was exactly 1.
But EFI 2.00 firmware is starting to appear, and the 2.00 changes don't
affect anything in Linux.

This patch implements PAL_VM_SUMMARY (and PAL_MEM_ATTRIB for good
measure) and pretends that the simulated machine is a McKinley.

Kernel 2.6 doesn't support egcs, and I didn't find any user of this

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).

Earlier fix in 4aec0fb12267718c750475f3404337ad13caa8f5 just
masked the real problem.

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.

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!
