ba1ed5240b SMP: Optimize ticket lock implementation 
This reverts the relevant part of commit
da06fe948c.  The acquire/release order is
superfluous for the next ticket increment.  The mutual exclusion is
guaranteed by the acquire load from and release store to the next
serving atomic variable.

258ad71e96 SMP: Fix and optimize thread dispatching 
According to the C11 and C++11 memory models only a read-modify-write
operation guarantees that we read the last value written in modification
order.  Avoid the sequential consistent thread fence and instead use the
inter-processor interrupt to set the thread dispatch necessary
indicator.

f52885b6bc ARMv7M: Improve exception handler routine and add comments on SP selection 
This patch adds a brief description of how context state is saved into the
SP on exception entry, and makes a few changes to _ARMV7M_Exception_default
in order to make it a bit more efficient. I also removed the unused 'v7mfsz'
input parameter.

This should apply over Sudarshan's patch.

bebfc4209b Beaglebone: fix missing clobber in inline assembly. 
flush_data_cache uses R0 directly but doesn't list it as a clobbered
register. Compiling with -O3 made this code break, since the function
that calls flush_data_cache already uses r0.

closes #2416.

41b5c915e3 cpukit/libmisc/dumpbuf/dumpbuf.c: Fix compilation warnings 
Compiling dumpbuf.c causes the following warning to be issued:

warning: pointer targets in passing argument 1 of 'snprintf' differ in signedness [-Wpointer-sign]

This happens because line_buffer is declared as unsigned.

Closes #2411.

28a870c47f cpukit/libnetworking/rtems/rtems_dhcp.c: Fix compilation error 
Apparently 'free' is defined as a macro which takes two arguments and calls
rtems_bsdnet_free. When fixing #2405 I added a missing 'free' but didn't notice
it was non-standard.

Closes #2410.
