This driver uses an 8254 timer to generate the pacer clock used for analog

Note that the pacer does not have to be stopped when starting a new async
command in pcl818_ai_cmd() or when the card is initialy reset by pcl818_reset().
The counters are all reset when the driver is initially attached and the
counters used by the pacer are stopped when a command is canceled.

Add a new member to the comedi_device struct for a comedi_8254 'pacer'. This
provides a convient place to store the data allocated by the comedi_8254 module
for boards that use an 8254 device to create the data acquisition pacer clock.

staging: comedi: comedi_8254: introduce module for 8254 timer support
A 8254 timer/counter is commonly used on data acquisition boards to provide
the internal pacer clock used to acquire analog input samples. Some boards
also to allow the timers to be used externally.
Currently the 8254 timers are supported by comedi using the 8253.h header
and a number of inline functions. This works for the internal pacer clock
but requires the drivers to implement subdevice code necessary to use the
timers externally.
Introduce a new module to support both the internal pacer clock and the
external counter subdevice. This will allow removing a bunch of duplicated
code in the drivers and standardizes the comedi 8254 timer support.
This implementation is based on the 8253.h inline functions and the various
subdevice functionality in the comedi drivers.

C99 says that a precision which is simply '.' with no following digits
or * should be interpreted as 0, which means that these format strings
actually mean 'print 16 spaces'. However, the kernel's printf
implementation treats this case as if the precision was omitted. Don't
rely on that quirk.

Staging: rtl8192e: Use ether_addr_copy() instead of memcpy()
This patch replaces memcpy with ether_addr_copy.
Also pathole was used to make sure that arguments passed to ether_addr_copy
are aligned to u16.
First argument is iwe.u.ap_addr.sa_data i output of pahole is:
struct iw_event {
__u16 len; /* 0 2 */
__u16 cmd; /* 2 2 */
/* XXX 4 bytes hole, try to pack */
union iwreq_data u; /* 8 16 */
/* size: 24, cachelines: 1, members: 3 */
/* sum members: 20, holes: 1, sum holes: 4 */
/* last cacheline: 24 bytes */
};
and inside union iwreq_data u is sa_data:
struct sockaddr {
/* typedef sa_family_t -> __kernel_sa_family_t */ short unsigned int sa_family; /* 8 2 */
char sa_data[14]; /* 10 14 */
} ap_addr; /* 16 */
sa_data is a char array of size 14, and the number of bytes copied using
ether_addr_copy() is 6.
Second argument is network->bssid and output of pahole is:
struct rtllib_network {
u8 bssid[6]; /* 0 6 */
u8 channel; /* 6 1 */
u8 ssid[33]; /* 7 33 */
u8 ssid_len; /* 40 1 */
u8 hidden_ssid[33]; /* 41 33 */
/* --- cacheline 1 boundary (64 bytes) was 10 bytes ago --- */
u8 hidden_ssid_len; /* 74 1 */
