iwlwifi: fix debugfs buffer handling
We keep track of where to write into a buffer by keeping a count of how
much has been written so far. When writing to the buffer we thus take the
buffer pointer and adding the count of what has been written so far.
Keeping track of what has been written so far is done by incrementing
this number every time something is written to the buffer with how much has
been written at that time.
Currently this number is incremented incorrectly when using the
"hex_dump_to_buffer" call to add data to the buffer. Fix this by only
adding what has been added to the buffer in that call instead of what has
been added since beginning of buffer.

bridge: Fix double-free in br_add_if.
There is a potential double-kfree in net/bridge/br_if.c. If br_fdb_insert
fails, then the kobject is put back (which calls kfree due to the kobject
release), and then kfree is called again on the net_bridge_port. This

This is because the driver manages interrupts without checking for
netif_running().
Though, there are few other issues with suspend/resume in this driver.
The intention of calling free_irq() in suspend() was to avoid any
possible spurious interrupts (see commit
5b039e681b8c5f30aac9cc04385
"3c59x PM fixes"). But,
- On resume, the driver was requesting IRQ just after pci_set_master(),
but before vortex_up() (which actually resets 3c59x chips).
- Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy
HW won't trigger spurious interrupts in another driver that
requested the same interrupt. So, if we want to protect from
unexpected interrupts, then on suspend we should issue disable_irq(),
not free_irq().

param: allow whitespace as kernel parameter separator
Some boot mechanisms require that kernel parameters are stored in a
separate file which is loaded to memory without further processing
(e.g. the "Load from FTP" method on s390). When such a file contains
newline characters, the kernel parameter preceding the newline might
not be correctly parsed (due to the newline being stuck to the end of
the actual parameter value) which can lead to boot failures.
This patch improves kernel command line usability in such a situation
by allowing generic whitespace characters as separators between kernel
parameters.

edac: i3200 memory controller driver
A driver for the Intel 3200 and 3210 memory controllers. It has only had
light testing so far, and currently makes no attempt to decode error
addresses at anything finer than csrow granularity.

edac: fix resource size calculation
Use the function resource_size, which reduces the chance of introducing
off-by-one errors in calculating the resource size.
The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
struct resource *res;
@@
- (res->end - res->start) + 1
+ resource_size(res)

edac: mpc85xx add mpc83xx support
Add support for the Freescale MPC83xx memory controller to the existing
driver for the Freescale MPC85xx memory controller. The only difference
between the two processors are in the CS_BNDS register parsing code, which
has been changed so it will work on both processors.
The L2 cache controller does not exist on the MPC83xx, but the OF
subsystem will not use the driver if the device is not present in the OF
device tree.
I had to change the nr_pages calculation to make the math work out. I
checked it on my board and did the math by hand for a 64GB 85xx using 64K
pages. In both cases, nr_pages * PAGE_SIZE comes out to the correct
value.
