The code in "1007:" is in the .fixup section, which in the mmuless
case is discarded. Since this code is referenced from the .text
section, it causes an link error. Move this code into the .text
section instead.

In noMMU mode, various of functions which are defined in mm/proc-*.S
is not valid or needed to be avoided. i.g. switch_mm is not needed,
just returns and this makes the I & D caches are valid which shows
great improvement of performance including task switching and IPC.

Hyok says Intel Xscale is not currently supported by uCLinux.
Rather than adding #error statements to the Xscale support files
and causing !MMU+Xscale configurations to fail to build, prevent
Xscale-based machines from being selected in !MMU mode.

Remove fault-armv.o, mmap.o and mm-armv.o from uclinux builds - these
are concerned with MMU-ful operations, and as such are redundant for
uclinux.
Since this also removes iotable_init() and iotable_init() is used
extensively in the platform support files, just make it a no-op.
Based upon a couple of patches by Hyok.

nommu doesn't have any form of remapping support, so ioremap, etc
become stubs which just return the casted address, doing nothing
else.
Move ioport_map(), ioport_unmap(), pci_iomap(), pci_iounmap()
into a separate file which is always built.

MMUless systems have only one address space for all threads, so
both the usual access_ok() checks, and the exception handling do
not make much sense.
Hence, discard the fixup and exception tables at link time, use
memcpy/memset for the user copy/clearing functions, and define
the permission check macros to be constants.
Some of this patch was derived from the equivalent patch by
Hyok S. Choi.

Since there can be no fixed location for the TLS value with nommu

Patch from Guennadi Liakhovetski
Currently probe_irq_on() on PXA will silently reconfigure all output GPIOs, that are not configured as alternate functions, for input. Avoid that. Upon CPU reset all GPIOs are configured as inputs, so, if a GPIO is configured as output, it has been done so intentionally.

Back in the days when we had armo (26-bit) and armv (32-bit) combined,
we had an additional layer to the uaccess macros to ensure correct
typing. Since we no longer have 26-bit in this tree, we no longer
need this layer, so eliminate it.

With Goto-san's patch, we can add new pgdat/node at runtime. I'm now
considering node-hot-add with cpu + memory on ACPI.
I found acpi container, which describes node, could evaluate cpu before
memory. This means cpu-hot-add occurs before memory hot add.
In most part, cpu-hot-add doesn't depend on node hot add. But register_cpu(),
which creates symbolic link from node to cpu, requires that node should be
onlined before register_cpu(). When a node is onlined, its pgdat should be
there.
This patch-set holds off creating symbolic link from node to cpu
until node is onlined.
This removes node arguments from register_cpu().
Now, register_cpu() requires 'struct node' as its argument. But the array of
struct node is now unified in driver/base/node.c now (By Goto's node hotplug
patch). We can get struct node in generic way. So, this argument is not
necessary now.
This patch also guarantees add cpu under node only when node is onlined. It
is necessary for node-hot-add vs. cpu-hot-add patch following this.
Moreover, register_cpu calculates cpu->node_id by cpu_to_node() without regard
to its 'struct node *root' argument. This patch removes it.
Also modify callers of register_cpu()/unregister_cpu, whose args are changed
by register-cpu-remove-node-struct patch.

Remove VM_LOCKED before remap_pfn range from device drivers and get rid of
VM_SHM.
remap_pfn_range() already sets VM_IO. There is no need to set VM_SHM since
it does nothing. VM_LOCKED is of no use since the remap_pfn_range does not
place pages on the LRU. The pages are therefore never subject to swap
anyways. Remove all the vm_flags settings before calling remap_pfn_range.
After removing all the vm_flag settings no use of VM_SHM is left. Drop it.

In order for userspace to find saved coprocessor registers, move them from
struct rt_sigframe into struct ucontext. Also allow space for glibc's
sigset_t, so that userspace and kernelspace can use the same ucontext
layout. Define the magic numbers for iWMMXt in the header file for easier
reference. Include the size of the coprocessor data in the magic numbers.
