Copy over the files from trace-cmd to the Linux tools directory
such that applications like perf and latencytrace can use the
more advanced parsing code.
Because some of the file names of perf conflict with trace-cmd file
names, the trace-cmd files have been renamed as follows:
parse-events.c ==> event-parse.c
parse-events.h ==> event-parse.h
utils.h ==> event-utils.h
The files have been updated to handle the changes to the header files
but other than that, they are identical to what was in the trace-cmd
repository. The history of these files, including authorship is
available at the git repo:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
The Makefile was also copied over, but most of it was removed to
focus on the parse-events code first. The parts of the Makefile for
the plugins have also been removed, but will be added back when the
plugin code is copied over as well. But that may be in its own
separate directory.

Move the trace-event-parse.c code that originally came from trace-cmd into
their own files. The new file will be called trace-parse-events.c, as
the name of trace-cmd's file was parse-events.c too, but it conflicted
with the parse-events.c file in perf that parses the command line.
This tries to update the code with mimimal changes.
Perf specific code stays in the trace-event-parse.[ch] files and
the common parsing code is now in trace-parse-events.c and
trace-parse-events.h.

... since exit_mmap() is coming and it will munmap() everything anyway.
In all other cases aio_free_ring() has ctx->mm == current->mm; moreover,
all other callers of vm_munmap() have mm == current->mm, so this will
allow us to get rid of mm argument of vm_munmap().

If the callback isn't defined, then we should run in PIO mode.

Commit c79396c191 ("mmc: sdhci: prevent card detection activity
for non-removable cards") disables card detection where the cards
are marked as non-removable.
This makes sense, but the implementation detail of calling
mmc_card_is_removable() causes some problems, because
mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME
semantics.
In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root
filesystem is stored on SD, but we also have external SD card slots
where we want automatic card detection.
Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE,
which is defined to mean that the card is *really* nonremovable. This
could be revisited in future if we find a way to improve
CONFIG_MMC_UNSAFE_RESUME semantics.

When dw_mci_pre_dma_transfer returns failure in some reasons,
dw_mci_submit_data will prepare to switch the PIO mode from DMA.
After switching to PIO mode, DMA(IDMAC in particular) is still
enabled. This makes the corruption in handling interrupt and
the driver lock-up.

This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.
This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have
to export our internal do_mmap_pgoff() function.
Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead. We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

Like the vm_brk() function, this is the same as "do_munmap()", except it
does the VM locking for the caller.

of_have_populated_dt() is not expected to be used in drivers but
instead only in early platform init code.
Drivers on the other hand should rely on dev->of_node or of_match_device().
Besides usage of of_have_populated_dt() also throws up build error as below
which was reported by Balaji TK, when omap_hsmmc is built as a module.
ERROR: "allnodes" [drivers/mmc/host/omap_hsmmc.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
So get rid of all of_have_populated_dt() usage in omap_hsmmc driver and
instead use dev->of_node to make the same dicisions as earlier.
