This patch fixes partly PAGE_SIZEs of 16K or 64K by adjusting the
assembler PTE lookup code and the assembler TEMPALIAS code.  Furthermore
some data alignments for PAGE_SIZE have been limited to 4K (or less) to
not waste too much memory with greater page sizes. As a side note, the
palo loader can (currently) only handle up to 10 ELF segments which is
fixed with tighter aligning as well.

My testings indicated that the ldci command in the sba iommu coding
needed adjustment by the PAGE_SHIFT value and that the I/O PDIR Page
size was only set to 4K for my machine (C3000).

All this fixes partly the boot, but there are still quite some caching
problems left.  Examples are e.g. the symbios logic driver which is
failing:

sym0: <896> rev 0x7 at pci 0000:00:0f.0 irq 69
sym0: PA-RISC Firmware, ID 7, Fast-40, SE, parity checking
CACHE TEST FAILED: DMA error (dstat=0x81).sym0: CACHE INCORRECTLY CONFIGURED.

and the tulip network driver which doesn't seem to work correctly
either:

Sending BOOTP requests .net eth0: Setting full-duplex based on MII#1
link partner capability of 05e1
..... timed out!

Beside those kernel fixes glibc will need fixes too to be able to handle
>4K page sizes.

The unwinder was being initialized way too late to be any use
debugging early boot crashes. Instead of relying on module_init
initcalls to initialize it, let's do it explicitly as early as
we can.

Bang in our own start_parisc call, which initializes the PDC
width, and turns on the FPU.

Previously, if CONFIG_PRINTK_TIME was on, we'd attempt to use
the FPU before we had enabled it, resulting in a difficult
to diagnose panic.

This patch causes init_per_cpu to redundantly set these for
cpu0, but this is harmless.

pdc_stable v0.30:

This patch introduces 3 more files to the /sys/firmware/stable tree:
- diagnostic, which contains a cryptic hex string
- osdep1, a 16 bytes os-dependent storage area always available
- osdep2, another os-dependent storage area which existence/size depends
on hversion.

This patch also adds code to setup the "Linux" signature in stable
storage. That is to say that starting with this patch, the kernel will
now sign its OSID (0x0006, thx LaMont) in Stable Storage upon boot,
whether pdc_stable is enabled or not.

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!
