PCI host bridge setup for SNI RM machines with PCI is quite broken, now
that Linux does it's resource setup own its own. It will use IO addresses,
which are needed by the EISA config detection and assigns PCI memory
addresses, which overlap with ISA legacy addresses (video ram). Below
is a patch, which changes the way how the PCI memory addresses are
used and sets the minimum IO address to give enough IO space for
8 EISA slots). This patch needs the other PCI resource change, I've
posted.

PCI based SNI RM machines have their EISA bus behind an Intel PCI/EISA
bridge. So the PCI IO range must start at 0x0000. Changing that will
break the PCI bus, because i8259.c already has registered it's IO
addresses before the PCI bus gets initialized. Below is a patch,
which will register the PCI host bridge resources inside
register_pci_controller(). It also changes i8259.c to use insert_region(),
because request_resource() will fail, if the IO space of the PIT hanging
of the PCI host bridge (maybe passing the resource parent to
init_i8259_irqs() is a cleaner fix for that).

s390 machines provide hardware support for creating Linux dumps on SCSI
disks. For creating a dump a special purpose dump Linux is used. The first
32 MB of memory are saved by the hardware before the dump Linux is
booted. Via an SCLP interface, the saved memory can be accessed from
Linux. This patch exports memory and registers of the crashed Linux to
userspace via a debugfs file. For more information refer to
Documentation/s390/zfcpdump.txt, which is included in this patch.

Generic bug implementation for s390. Will increase the value of the
console output on BUG() statements since registers r0-r5,r14 will
not be clobbered by a printk() call that was previously done before
the illegal instruction of BUG() was hit.
Also implements an architecture specific WARN_ON(). Output of that
could be increased but requires common code change.

Second a disassembler is added that decodes the instructions surrounding
the faulting PSW. The output of a test oops now looks like this:

With the current strategy of using the bootmem allocator to allocate
or reserve framebuffer memory, there's a slight chance that the
requested area has been taken by the boot allocator bitmap before we
get around to reserving it.
By inserting the framebuffer region as a reserved region as early as
possible, we improve our chances for success and we make the region
visible as a reserved region in dmesg and /proc/iomem without any
extra work.

Use struct resource to specify both physical memory regions and
reserved regions and push everything into the same framework,
including kernel code/data and initrd memory. This allows us to get
rid of many special cases in the bootmem initialization and will also
make it easier to implement more robust handling of framebuffer
memory later.

Fix the I/O access macros so that they work with externally connected
devices accessed in little-endian mode over any bus width:
* Use a set of macros to define I/O port- and memory operations
borrowed from MIPS.
* Allow subarchitecture to specify address- and data-mangling
* Implement at32ap-specific port mangling (with build-time
configurable bus width. Only one bus width at a time supported
for now.)
* Rewrite iowriteN and friends to use write[bwl] and friends
(not the __raw counterparts.)
This has been tested using pata_pcmcia to access a CompactFlash card
connected to the EBI (16-bit bus width.)
