Most peripherals on the i.MX51 have an Off-Platform Peripheral Access
Control Register (OPACR) in which the access rights (together with the
MPROT registers) can be declared.
However, this does not seem to work for example for SSI1+SDMA, because the
supervisor bit is not set for the SDMA unit.
A similar problem was described in the patch for i.MX53 CPU
(ARM: i.MX53: globally disable supervisor protect), and the same solution
is applicable for i.MX51 CPU.
Patch has tested on custom board based on Digi CCMX-51 module (i.MX51).

waking the CPUs when they are in wait(unclocked) state. As the hardware
workaround isn't applicable to all boards, disable the deeper idle state
when the workaround isn't present and the FEC is in use.
This allows to safely run a kernel with CPUidle enabled on all i.MX6
boards.

Two current fixes: one affects Qemu CD ROM emulation, which stopped
working after the updates in SCSI to require VPD pages from all
conformant devices. Fix temporarily by blacklisting Qemu (we can
relax later when they come into compliance). The other is a fix to
the optimal transfer size. We set up a minefield for ourselves by
being confused about whether the limits are in bytes or sectors (SCSI
optimal is in blocks and the queue parameter is in bytes). This tries
to fix the problem (wrong setting for queue limits max_sectors) and
make the problem more obvious by introducing a wrapper function.

Merge filesystem stacking fixes from Jann Horn.
* emailed patches from Jann Horn <jannh@google.com>:
sched: panic on corrupted stack end
ecryptfs: forbid opening files without mmap handler
proc: prevent stacking filesystems on top
Until now, hitting this BUG_ON caused a recursive oops (because oops
handling involves do_exit(), which calls into the scheduler, which in
turn raises an oops), which caused stuff below the stack to be
overwritten until a panic happened (e.g. via an oops in interrupt
context, caused by the overwritten CPU index in the thread_info).
Just panic directly.

This prevents users from triggering a stack overflow through a recursive
invocation of pagefault handling that involves mapping procfs files into
virtual memory.

This prevents stacking filesystems (ecryptfs and overlayfs) from using
procfs as lower filesystem. There is too much magic going on inside
procfs, and there is no good reason to stack stuff on top of procfs.
(For example, procfs does access checks in VFS open handlers, and
ecryptfs by design calls open handlers from a kernel thread that doesn't
drop privileges or so.)
