[PARISC] Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the casts

The following build error occured during a parisc build with
swap-over-NFS patches applied.

net/core/sock.c:274:36: error: initializer element is not constant
net/core/sock.c:274:36: error: (near initialization for 'memalloc_socks')
net/core/sock.c:274:36: error: initializer element is not constant

Dave Anglin says:
> Here is the line in sock.i:
>
> struct static_key memalloc_socks = ((struct static_key) { .enabled =
> ((atomic_t) { (0) }) });

The above line contains two compound literals.  It also uses a designated
initializer to initialize the field enabled.  A compound literal is not a
constant expression.

The location of the above statement isn't fully clear, but if a compound
literal occurs outside the body of a function, the initializer list must
consist of constant expressions.

[PARISC] fix personality flag check in copy_thread()

Directly comparing task_struct->personality against PER_* is not fully
correct, as it doesn't take flags potentially stored in top three bytes
into account.

Analogically, directly forcefully setting personality to PER_LINUX32 or
PER_LINUX discards any flags stored in the top three bytes.

openvswitch: Relax set header validation.

When installing a flow with an action to set a particular field we
need to validate that the packets that are part of the flow actually
contain that header.  With IP we use zeroed addresses and with TCP/UDP
the check is for zeroed ports.  This check is overly broad and can catch
packets like DHCP requests that have a zero source address in a
legitimate header.  This changes the check to look for a zeroed protocol
number for IP or for both ports be zero for TCP/UDP before considering
the header to not exist.

ASoC: ux500_msp_i2s: better use devm functions and fix error return code

Remove unnecessary calls to devm_kfree and replace iounmap by devm_iounmap
(and use resource_size for the third argument).  These changes make it
possible to remove the error-handling code at the end of
ux500_msp_i2s_init_msp, and all of the gotos become direct returns.

In the case of the second call to devm_kzalloc, the return variable ret was
not initialized.  Here it is changed to a direct return of -ENOMEM.

follows: (http://coccinelle.lip6.fr/)

s390: Always use "long" for ssize_t to match size_t

On s390x-linux-gcc, __SIZE_TYPE__ expands to "long unsigned int" for both
32-bit s390 and 64-bit s390x, as
gcc-4.6.3-nolibc/s390x-linux/lib/gcc/s390x-linux/4.6.3/plugin/include/config/s390/linux.h
has

    #define SIZE_TYPE (TARGET_64BIT ? "long unsigned int" : "long unsigned int")

To match this, __kernel_size_t is always set to "long unsigned int".

But while __kernel_ssize_t is "long" on 64-bit s390x, it is "int" on 32-bit
s390, causing compiler warnings like:

    fs/quota/quota_tree.c:372:4: warning: format '%zd' expects argument of type 'signed size_t', but argument 4 has type 'ssize_t' [-Wformat]

To fix this, __kernel_ssize_t should be "long", irrespective of word size.

ath5k: fix wrong max power per rate eeprom reads for 802.11a

This patch reduces the per rate target power eeprom reads for
AR5K_EEPROM_MODE_11A from 10 to 8, as there are only 8 valid
power curve entries on the eeprom. The former 10 reads lead to
equal max power limits per rate and this causes an increasing
distortion for all rates above 24 MBit and leads to a needless
poor performance in 802.11a mode.
