[Blackfin] arch: Blackfin checksum annotations
FSVOtest in this case, since I don't have the hardware...
However, all changes seen by gcc are actually
 - explicit cast to unsigned short in return expression of functions
    returning unsigned short
 - csum_fold() return type changed from unsigned int to __sum16
   (unsigned short), same as for all other architecture and as net/* expects;
   expression actually returned is ((~(sum << 16)) >> 16) with sum being
   unsigned 32bit, so it's (a) going to fit into the range of unsigned short
   and (b) had been unsigned all along, so no sign expansion mess happened.

[Blackfin] arch: fix gdb testing regression
When transferring to IRQ5 from an exception, save SYSCFG in memory across the
transfer and clear the trace bit.

When we get a single step exception, check whether we can safely clear the
trace bit in SYSCFG.  We can (and should) clear it after the first instruction
of the interrupt handler; the first insn saves SYSCFG to the stack in all
handlers.

kernel: Move arches to use common unaligned access
Unaligned access is ok for the following arches:
cris, m68k, mn10300, powerpc, s390, x86

Arches that use the memmove implementation for native endian, and
the byteshifting for the opposite endianness.
h8300, m32r, xtensa

Packed struct for native endian, byteshifting for other endian:
alpha, blackfin, ia64, parisc, sparc, sparc64, mips, sh

m86knommu is generic_be for Coldfire, otherwise unaligned access is ok.

frv, arm chooses endianness based on compiler settings, uses the byteshifting
versions.  Remove the unaligned trap handler from frv as it is now unused.

v850 is le, uses the byteshifting versions for both be and le.

Remove the now unused asm-generic implementation.

[Blackfin] arch: Prevent potential Core Hang situation
If the new value written to the PLL_CTL or VR_CTL register is the
same as the previous value, the PLL wake-up will occur immediately
(PLL is already locked), but the core and system clock will be
bypassed for the PLL_LOCKCNT duration. For this interval, code will
execute at the CLKIN rate instead of at the expected CCLK rate.
Software should guard against this condition by comparing the
current value to the new value before writing the new value.

[Blackfin] arch: This allows XIP to work with FD-PIC.
Previously, init failed to do anything meaningful;
it turns out that the reason is that FD-PIC has a readonly data
section which can be located in the XIP filesystem, and various address checks
in the kernel reject such addresses for syscall arguments.  Hence, init's
  execve ("/bin/sh", ...)
failed with error code EFAULT.

There's room for improvement here: in case people want to have filesystems
on flash rather than in main memory, _access_ok should be modified to
allow this.

This bug fix is also dedicated to Michael Hennerich.

[Blackfin] arch: relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file where it actually gets used.
relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file
where it actually gets used.  this way when we change
CONFIG_MEM_SIZE in our kconfig, we only rebuild one or two files
rather than a whole bunch that implicitly include cplb.h.

this will also remove the ability to clear the swapcount on
the fly, but i really dont think that functionality is important.

ultimate goal is for CONFIG_MEM_SIZE to go away and calculate
this value on the fly based on what u-boot programmed for us.

[Blackfin] arch: fix bug - when using trace buffer with CONFIG_MPU enabled.
There were a couple of problems with the way the trace buffer state
is saved/restored in assembly.  The DEBUG_HWTRACE_SAVE/RESTORE macros
save a value to the stack, which is not immediately obvious; the CPLB
exception code needed changes to load the correct value of the stack
pointer.  The other problem is that the SAVE/RESTORE macros weren't
pushing and popping the value downwards on the stack, but rather moving
it _upwards_, which is of course completely broken.

We also need to make sure there's a matching DEBUG_HWTRACE_RESTORE in
the error case of the CPLB handler.

kvm: provide kvm.h for all architecture: fixes headers_install
Currently include/linux/kvm.h is not considered by make headers_install,
because Kbuild cannot handle " unifdef-$(CONFIG_FOO) += foo.h.  This problem
was introduced by

commit fb56dbb31c
Author: Avi Kivity <avi@qumranet.com>
Date:   Sun Dec 2 10:50:06 2007 +0200

    KVM: Export include/linux/kvm.h only if $ARCH actually supports KVM

    Currently, make headers_check barfs due to <asm/kvm.h>, which <linux/kvm.h>
    includes, not existing.  Rather than add a zillion <asm/kvm.h>s, export kvm.
    only if the arch actually supports it.

    Signed-off-by: Avi Kivity <avi@qumranet.com>

which makes this an 2.6.25 regression.

One way of solving the issue is to enhance Kbuild, but Avi and David conviced
me, that changing headers_install is not the way to go.  This patch changes
the definition for linux/kvm.h to unifdef-y.

If  unifdef-y is used for linux/kvm.h "make headers_check" will fail on all
architectures without asm/kvm.h.  Therefore, this patch also provides
asm/kvm.h on all architectures.
