* Rename ARM_HAVE_MP_EXTENSIONS to ARM_USE_MP_EXTENSIONS and extend it to
handle more cases, including when SMP is not enabled.
* Check ARM_USE_MP_EXTENSIONS when building for ARMv7+, even if no SMP.
* Use ARM_USE_MP_EXTENSIONS in pmap-v6.c to detect when to set PRRR_NS1.
With this we should be able to boot on all ARMv7+ Cortex-A cores with
32-bit support.

If dotdot lookup does not escape from the file descriptor passed as
the lookup root, we can allow the component traversal. Track the
directories traversed, and check the result of dotdot lookup against
the recorded list of the directory vnodes.
Dotdot lookups are enabled by sysctl vfs.lookup_cap_dotdot, currently
disabled by default until more verification of the approach is done.
Disallow non-local filesystems for dotdot, since remote server might
conspire with the local process to allow it to escape the namespace.
This might be too cautious, provide the knob
vfs.lookup_cap_dotdot_nonlocal to override as well.

process of being unmounted. Previously it would skip them, even if the
unmount eventually failed eg due to the filesystem being busy.
This behaviour broke autounmountd(8) - if you tried to manually unmount
a mounted filesystem, using 'automount -u', and the autounmountd attempted
to refresh the filesystem list in that very moment, it would conclude that
the filesystem got unmounted and not try to unmount it afterwards.

Summary:
i.MX5 and PowerPC use a very similar eSDHC controller, which is also
similar to the uSDHC controller used by i.MX6. The imx_sdhci driver works
almost completely with PowerPC, with some minor tweaks.
There is one caveat with this: reset currently does not work on PowerPC, so has
been #ifdef'd out until this can be tracked down and fixed. If resets are done
the controller will timeout all data transactions. Without a reset, it appears
to work just fine.
This is part 3, following up r308186 and r308187.
Test Plan:
This has been tested on a PowerPC QorIQ P1022 board. It has not been
tested on i.MX, but no regressions are expected.

Some controllers (namely Freescale's eSDHC, tested) will continue to assert
the card removed or card insert interrupts even after being handled. To work
around this, disable watching the interrupt that just occurred until the

Linux has a similar change in its driver to address the same problem.

This paves the way for a contiguous descriptor array.
A contiguous descriptor array has the benefit that we can make strong
assertions about whether an address is a valid descriptor or not. The
other benefit is that future generations of I/OAT hardware will require
a contiguous descriptor array anyway. The downside is that after system
boot, big chunks of contiguous memory is much harder to find. So
dynamic scaling after boot is basically impossible.

it shouldn't be enabled in release builds.
Function names (or arbitrary string constants) are tracked in a
