The recent vsnprintf() fix introduced an off-by-one, and it's now
possible to overrun the target buffer by one byte.
The "end" pointer points to past the end of the buffer, so if we
have to truncate the result, it needs to be done though "end[-1]".
[ This is just an alternate and simpler patch to one proposed by Andrew
and Jeremy, who actually noticed the problem ]

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

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.

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.

Majorily based on Hyok Choi's patches, this fixes up the asm-arm
header files for mmuless systems. Over and above Hyok's patches:
- nommu.h merged into mmu.h (it's only a structure)
- nommu_context.h is essentially the same as mmu_context.h, but
without the MM switching code.
so there's no point having separate files. Also, in memory.h,
there's no point #ifndef'ing PHYS_OFFSET and END_MEM - both
CONFIG_DRAM_BASE and CONFIG_DRAM_SIZE will always be set by the
configuration scripts.
Other files have minor formatting changes, but are essentially
the same. Hyok's original patches were signed off thusly:

Since there can be no fixed location for the TLS value with nommu
systems, we must provide TLS register emulation in order to support
TLS binaries on CPUs without the thread register.

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.

Patch from Lennert Buytenhek
ixp23xx was including asm/hardware.h in its version of uncompress.h,
to get at the physical address of the debug UART, but this include was
causing various inline functions that are totally unrelated to the
decompressor, defined in headers in include/asm-arm/arch-ixp23xx, to
be included in the decompressor image.
Include asm/arch/ixp23xx.h instead, and move the sole inline function
in ixp23xx.h to another header.

Some watchdog drivers have the ability to report the remaining time
before the system will reboot. With the WDIOC_GETTIMELEFT ioctl
you can now read the time left before the watchdog would reboot
your system.

i8xx_tco.c, pcwd_pci.c and pcwd_usb.c .

Some watchdog timers support the concept of a "pretimeout" which
occurs some time before the real timeout. The pretimeout can
be delivered via an interrupt or NMI and can be used to panic
the system when it occurs (so you get useful information instead
of a blind reboot).

This patch adds earlier initialization of spi_device.mode, as needed
on boards using nondefault chipselect polarity. An example would be
ones using the RS5C348 RTC without an external signal inverter between
the RTC chipselect and the SPI controller.
Without this mechanism, the first setup() call for that chip would
wrongly enable chips, corrupting transfers to/from other chips sharing
that SPI bus.
