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).

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

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.

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!
