34fc8742e2 Add support for microcode update on newer AMD CPUs (10h+)
This includes new code for parsing microcode files as well as
the kernel-side change to apply the update on all processors
at the same time.

Developed with help from Borislav Petkov, formerly bp@amd64.org.

Tested using Athlon II X2 processor on a system where BIOS does
not have the latest microcode version:
/boot/firmware/microcode_amd.bin: updating cpu /dev/cpuctl0 to revision 0x10000c7... done.

The microcode file is taken from here:
https://web.archive.org/web/20160528230514/http://www.amd64.org/microcode.html
(note that the original site seems to be down at the moment)
It can also be found here:

808cc562eb Add a fallback to the device mapper logic. We've seen systems in the field
that are apparently misconfigured by the manufacturer and cause the mapping
logic to fail.  The fallback allows drive numbers to be assigned based on the
PHY number that they're attached to.  Add sysctls and tunables to overrid
this new behavior, but they should be considered only necessary for debugging.

00a1afd4d0 Allow an SMP kernel to boot on Cortex-A8:
* 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.

a41f4cc9a5 Allow some dotdot lookups in capability mode.
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.

2c0de38912 Fix getfsstat(2) with MNT_WAIT to not skip filesystems that are in the
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.

4bdfc573a9 Merge i.MX and PowerPC SDHCI drivers
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.

the card removed or card insert interrupts even after being handled.  To work
around this, disable watching the interrupt that just occurred until the
opposite interrupt is triggered.

77a763e63a ioat(4): Simplify by removing dynamic scaling
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.
