There are some efforts going on to have flexcan_switch function
implemented in flexcan driver, so that this platform function hook
can be saved for device tree boot.  But due to the mx28evk board
design oddness that two flexcan transceivers share one switch gpio,
we have to come up a separate and generic gpio-switch driver to handle
all these gpio switch use cases.

Before that happens, we choose to use auxdata to pass flexcan_switch
function hook, so that the DT conversion is not blocked there.

For non-DT boot, function tx28_add_fec0 configures all ENET0 pins
into gpio mode for resetting fec phy, and then reconfigures those pins
into ENET function after that.

For DT boot, all the pin configuration is done by pinctrl subsystem.
Ideally, when gpio_request gets called, GPIO subsystem should call
pinctrl to configure pins into gpio mode automatically, and have pins
freed up from pinctrl subsystem when gpio_free is called.  But right
now, this cooperation between gpio and pinctrl hasn't been available.
As the result, we have to explicitly call pinctrl_get_select and
pinctrl_put for device tree boot.

Following a report of a crash during an automount expire I found that
the locking in fs/autofs4/expire.c:get_next_positive_subdir() was wrong.
Not only is the locking wrong but the function is more complex than it
needs to be.

The function is meant to calculate (and dget) the next entry in the list
of directories contained in the root of an autofs mount point (an autofs
indirect mount to be precise). The main problem was that the d_lock of
the owner of the list was not being taken when walking the list, which
lead to list corruption under load. The only other lock that needs to
be taken is against the next dentry candidate so it can be checked for
usability.

- apply the tlb invalidate w/a

Otherwise we still have another gmbus regression (patches are awaiting
tested-bys) and there's something odd going with some rare systems not
entering rc6 often enough (and hence blowing through too much power).  It
seems to be a timing-related issue and can be mitigated by frobbing the
magic tuning parameters. We're still working on that one. Also, we still
have some fallout from the hw context support, but you can only hit that
