Don't pass the advanced position to strlcat() but just gives the buffer
head position so that the max size limit can be checked correctly.
Introduced a new helper function to standaralize strlcat() calls.

On Soundblaster X-FI Titenium with emu20k2 the SIDE and SURROUND mute
functions are swapped.
It was checked with 'speaker-test -c 8 -s 3' and (un)mute surround or
'speaker-test -c 8 -s 7' and (un)mute side. The volume seems not
to be affected and works as expected.

The client->driver pointer can be NULL when i2c-device probing fails
in i2c_new_device(). This patch adds the NULL checks for client->driver
and return the error instead of blind assumption of driver availability.

On a 256M filesystem, doing this in a loop:
xfs_io -F -f -d -c 'pwrite 0 64m' test
rm -f test
eventually leads to ENOSPC. (the xfs_io command does a
64m direct IO write to the file "test")
As with other block allocation callers, it looks like we need to
potentially retry the allocations on the initial ENOSPC.

This fixes the following warning:

fs/ext4/inode.c:5615: warning: unused variable 'current_handle'
We remove the jbd_debug() statement which does use current_handle, as
it's not terribly important in the grand scheme of things.

Currently, on ARMv6 and ARMv7, if an application tries to execute
code (or garbage) on non-executable page it hangs. It caused by
incorrect prefetch abort handling. Now every prefetch abort
processes as a translation fault.
To fix this we have to analyze instruction fault status register
to figure out reason why we've got the abort and process it
accordingly.
To make IFSR different from DFSR we set bit 31 which is reserved in
both IFSR and DFSR.
This patch also tries to protect from future hangs on unexpected
exceptions. An application will be killed if unexpected exception
type was received.

Instruction fault status register, IFSR, was introduced on ARMv6 to
provide status information about the last insturction fault. It
needed for proper prefetch abort handling.
Now we have three prefetch abort model:
* legacy - for CPUs before ARMv6. They doesn't provide neither
IFSR nor IFAR. We simulate IFSR with section translation fault
status for them to generalize code;
* ARMv6 - provides IFSR, but not IFAR;
* ARMv7 - provides both IFSR and IFAR.

Commit 1522ac3ec95ff0230e7aa516f86b674fdf72866c
("Fix virtual to physical translation macro corner cases")
breaks the end of memory check in valid_phys_addr_range().
The modified expression results in the apparent /dev/mem size
being 2 bytes smaller than what it actually is.
This patch reworks the expression to correctly check the address,
while maintaining use of a valid address to __pa().

There are two 64 MB outbound memory windows at bus addresses
0x80000000..0x83ffffff and 0x84000000..0x87ffffff for PCI
memory. Currently, on iop32x, only the lower window is available for
allocations, limiting the available space to 64 MB. On iop33x the full
128 MB can be allocated, but the translation value is wrong for the
upper window.
The patch enables the full 128 MB space on iop32x and corrects the
initialization of OMWTVR1. Redundant definitions are deleted. Tested
using a Thecus N2100 board with a graphics adapter in the expansion
slot. Both windows are in use:

Commit 181f817eaaca4c1f introduced some new code to entry-common.S
Sadly, this new code uses 'bx' instruction which is available only on
ARMv5 and higher CPUs. This causes following compilation errors when
building kernel for StrongARM (ARMv4):
arch/arm/kernel/entry-common.S: Assembler messages:
arch/arm/kernel/entry-common.S:129: Error: selected processor does not
support `bx ip'
arch/arm/kernel/entry-common.S:138: Error: selected processor does not
support `bx ip'
Fix these errors by using 'mov pc' instead of 'bx'.

Fix:
WARNING: vmlinux.o(.text+0x247c): Section mismatch in reference from the function cpu_idle() to the function .cpuexit.text:cpu_die()
The function cpu_idle() references a function in an exit section.
Often the function cpu_die() has valid usage outside the exit section
and the fix is to remove the __cpuexit annotation of cpu_die.
WARNING: vmlinux.o(.cpuexit.text+0x3c): Section mismatch in reference from the function cpu_die() to the function .cpuinit.text:secondary_start_kernel()
The function __cpuexit cpu_die() references
a function __cpuinit secondary_start_kernel().
This is often seen when error handling in the exit function
uses functionality in the init path.
The fix is often to remove the __cpuinit annotation of
secondary_start_kernel() so it may be used outside an init section.
Sam says:
> The annotation of cpu_die() is wrong.
> To be annotated __cpuexit the function shall:
> - be used in exit context and only in exit context with HOTPLUG_CPU=n
> - be used outside exit context with HOTPLUG_CPU=y
So, this also means __cpu_disable(), __cpu_die() and twd_timer_stop() are
also wrong. However, removing __cpuexit from cpu_die() creates:
WARNING: vmlinux.o(.text+0x6834): Section mismatch in reference from the function cpu_die() to the function .cpuinit.text:secondary_start_kernel()
The function cpu_die() references
the function __cpuinit secondary_start_kernel().
This is often because cpu_die lacks a __cpuinit
annotation or the annotation of secondary_start_kernel is wrong.
so fix this using __ref.

We suffer an unfortunate combination of "features" which makes highmem
support on platforms without hardware TLB maintainence broadcast difficult:
- we need kmap_high_get() support for DMA cache coherence
- this requires kmap_high() to take a spinlock with IRQs disabled
- kmap_high() occasionally calls flush_all_zero_pkmaps() to clear
out old mappings
- flush_all_zero_pkmaps() calls flush_tlb_kernel_range(), which
on s/w IPI'd systems eventually calls smp_call_function_many()
- smp_call_function_many() must not be called with IRQs disabled:

This fixes the problem of not handling the NETDEV_UP event properly
during hot-plug or modprobe of bnx2 after cnic. The handling was
skipped by mistakenly using "else if" to check for the event.
Also update version to 2.0.1.
