So mem-memcpy.c started out as a simple memcpy() benchmark, then it grew
memset() functionality and now I plan to add string copy benchmarks as
well.
This makes the file name a misnomer: rename it to the more generic
mem-functions.c name.

However it'd be better to see them only -v option is given. To do that,

Currently, when 'perf test' is run by a normal user, it'll fail to
access tracepoint events. The output becomes somewhat messy because it
tries to be nice with long error messages and hints.
IMHO this is not needed for 'perf test' by default and AFAIK 'perf test'
uses pr_debug() rather than pr_err() for such messages so that one can
use -v option to see further details on failed testcases if needed.

Unlike perf callchain relying on walk_stackframe(), dump_backtrace()
has its own backtrace logic. A major difference between them is the
moment a symbol is recorded. Perf writes down a symbol *before*
calling unwind_frame(), but dump_backtrace() prints it out *after*
unwind_frame(). As a result, the last valid symbol cannot be hooked
in case of dump_backtrace(). This patch addresses the issue as
synchronising dump_backtrace() with perf callchain.
A simple test and its results are as follows:
- crash trigger
$ sudo echo c > /proc/sysrq-trigger
- current status
Call trace:
[<fffffe00003dc738>] sysrq_handle_crash+0x24/0x30

Note that this patch does not cover a case where MMU is disabled. The
last stack frame of swapper, for example, has PC in a form of physical
address. Unfortunately, a simple conversion using phys_to_virt() cannot
cover all scenarios since PC is retrieved from LR - 4, not LR. It is
a big tradeoff to change both head.S and unwind_frame() for only a few
of symbols in *.S. Thus, this hunk does not take care of the case.

HOSTCC arch/arm/vdso/vdsomunge
arch/arm/vdso/vdsomunge.c:48:22: fatal error: byteswap.h: No such file or directory
Observed: with omap2plus_defconfig and compile on Mac OS X with arm ELF
cross-compiler.
Reason: byteswap.h is a glibc only header.
Solution: replace by private byte-swapping macros (taken from
arch/mips/boot/elf2ecoff.c and kindly improved by Russell King)
Tested to compile on Mac OS X 10.9.5 host.

MMC data lines may be left floating if nothing is currently driving the
data lines, which is the case when mmc is in idle state, thus consuming
a useless extra amount of power. Add pullup on mmc2 data signals in the
same way it was previously done for mmc0 and mmc1.

The PMC is not only used to drive the clocks but also has some registers
related to other functions. One of those is for example the USB gadget
bias.
Using a syscon allows to properly separate those functions.

drm_edid.c now computes the alternate CEA clocks using
DIV_ROUND_CLOSEST(), so follow suit in the N/CTS setup to make sure we
pick the right setting for the mode.
Unfortunately we can't actually use DIV_ROUND_CLOSEST() here due to the
({}) construct used, so just stick in raw numbers instead.

Some omaps are producing imprecise external aborts because we are
wrongly trying to init SRAM for device tree based booting. Only
omap3 is still using the legacy SRAM code, so we need to make it
omap3 specific. Otherwise we can get errors like this on at least
dm814x:

Let's fix the issue by making sure omap_sdrc_init only gets called for
omap3. To do that, we need to have compatible "ti,omap3" in the dts
files. And let's also use "ti,omap3630" instead of "ti,omap36xx" like
we're supposed to.
