Subject: [PARISC] Use page allocator instead of slab allocator in pci-dma.c

Slab pages obtained via kmalloc are not cacheline aligned.  Nor is it
advisable to perform VM operations designed for page allocator pages on
memory obtained via kmalloc.

So replace the page sized allocations in kernel/pci-dma.c with page allocator
pages.

Subject: [PARISC] import necessary bits of libgcc.a

Currently we're hacking libs-y to include libgcc.a, but this has
unforeseen consequences since the userspace libgcc is linked with fpregs
enabled. We need the kernel to stop using fpregs in an uncontrolled manner
to implement lazy fpu state saves.

Introduce a consistent layout of vmlinux.
The same layout has been introduced for most
architectures.

And the same time move a few label definitions inside
the curly brackets so they are assigned the correct
starting address. Before a ld inserted alignment
would have casued the label to pint before the actual
start of the section.

Subject: [PARISC] Kill off ASM_PAGE_SIZE use

We have the macro _AC() generally available now
so the calculation of PAGE_SIZE can be made
assembler compatible.
Introduce use of _AC() and kill all users of
ASM_PAGE_SIZE.

Subject: [PARISC] Fix infinite loop in /proc/iomem

pcibios_link_hba_resources() could corrupt the resource tree by inserting
resources in the wrong place.  Fix this by calling pci_claim_resource()
for PCI-PCI bridges.  Delete pcibios_link_hba_resources as we shouldn't
need it any more.  Also get rid of lba_claim_dev_resources() and just
call pci_claim_resource() directly.
