Add DMA Engine API driver for the PL330 DMAC.
This driver is supposed to be reusable by various
platforms that have one or more PL330 DMACs.
Atm, DMA_SLAVE and DMA_MEMCPY capabilities have been
implemented.

The hists__tty_browse_tree function was created with the loop to print
all events, and its equivalent, hists__tui_browse_tree, was created in a
similar fashion, where it is possible to switch among the multiple
events, if present, using TAB to go the next event, and shift+TAB
(UNTAB) to go to the previous.
The report TUI now shows as the window title the name of the event and a
leak was fixed wrt pstacks.

It was assuming that the cache was always available and also wasn't
checking if the file found in the build id cache was just a kallsyms
file, that is not supported by objdump for disassembly.

Between problems with Kconfig and merging commits from several
different sources, it seems the s5pc100 build's move from plat-s5pc11
has had a few problems.
Since I do not have the trees to rebuild this quickly, the easiest
thing is to simply fix the errors found once the s5pc100_defconfig
actually builds.

Samsung's Soc S5PC100 has three PL330 DMACs. First is dedicated for
Memory->Memory data transfer while the other two meant for data
transfer with peripherals.

S5PC100 platform.

Add a little strncpy optimization which can easily cut boot time by 20%.
When the kernel is booting with initramfs, it builds up the filesystem
from a cpio archive by calling strncpy_from_user() via fs/namei.c's
do_getname() on every file in the archive (which can be lots) with a
length of PATH_MAX (1024). This causes the dest of the strncpy to be
padded with many NUL bytes.
This optimization mostly causes these NUL bytes to be padded with a call
to memset() which is already optimized for filling memory quickly, but
the hardware loop helps a little bit as well.
Boot time measured with 'loglevel=0' so UART speed doesn't get in the way.

The IADDR2DTEST() macro had some duplicated logic with bit 11 and some
incorrect comments, so scrub all of that.
In order to verify these aren't a problem (and won't be in the future),
extend the self tests to operate on as much L1 SRAM as possible.

Since 'extern inline' doesn't work correctly in the context of the Linux
kernel (too many overriding defines), move the string functions to normal
lib/ assembly files (like the existing mem funcs). This avoids the forced
inline all over the kernel and allows us to place them constantly in L1.
This also avoids some module failures when gcc inserts calls to string
functions but the kernel build system doesn't fully consult the library
archives.

While the CC pseudo register can be deduced from the ASTAT register, make
sure we set its value correctly instead of always stubbing it out as 0.
GDB itself looks at this pseudo register instead of ASTAT, so we have to
supply the right value.

NMIs are not safe to return from because many anomaly workarounds are
implemented by disabling interrupts. The NMI obviously violates this
assumption. Since the NMI watchdog never returns, we don't have to
worry about it clobbering RETN when it is being used as a scratch register
with the exception stack.

A few pseudo debug insns exist to make testing of simulators easier.
Since these don't actually exist in the hardware, we have to have the
exception handler take care of emulating these. This allows sim test
cases to be executed unmodified under Linux and thus simplify debugging
greatly.
