b6c24de77c slabinfo: fall back from /sys/kernel/slab to /sys/slab
I keep running upstream and mm kernels and the location of the slab
directory is different since upstream still uses /sys/slab.  This patch
makes slabinfo check /sys/slab if /sys/kernel/slab is not there.  Makes
slabinfo work on any kernel.

3326732570 libata: implement libata.force module parameter
This patch implements libata.force module parameter which can
selectively override ATA port, link and device configurations
including cable type, SATA PHY SPD limit, transfer mode and NCQ.

For example, you can say "use 1.5Gbps for all fan-out ports attached
to the second port but allow 3.0Gbps for the PMP device itself, oh,
the device attached to the third fan-out port chokes on NCQ and
shouldn't go over UDMA4" by the following.

 libata.force=2:1.5g,2.15:3.0g,2.03:noncq,udma4

is removed now with this patch. a.out ELF interpreters were an transition
feature for moving a.out systems to ELF, but they're unlikely to be still
needed. Pure a.out systems will still work of course. This allows to
simplify the hairy ELF loader.

f84e3f521e mount options: add documentation
This series addresses the problem of showing mount options in
/proc/mounts.

Several filesystems which use mount options, have not implemented a
.show_options superblock operation.  Several others have implemented
this callback, but have not kept it fully up to date with the parsed
options.

Q: Why do we need correct option showing in /proc/mounts?
A: We want /proc/mounts to fully replace /etc/mtab.  The reasons for
   this are:
    - unprivileged mounters won't be able to update /etc/mtab
    - /etc/mtab doesn't work with private mount namespaces
    - /etc/mtab can become out-of-sync with reality

Q: Can't this be done, so that filesystems need not bother with
   implementing a .show_mounts callback, and keeping it up to date?
A: Only in some cases.  Certain filesystems allow modification of a
   subset of options in their remount_fs method.  It is not possible
   to take this into account without knowing exactly how the
   filesystem handles options.

For the simple case (no remount or remount resets all options) the
patchset introduces two helpers:

  generic_show_options()
  save_mount_options()

These can also be used to emulate the old /etc/mtab behavior, until
proper support is added.  Even if this is not 100% correct, it's still
better than showing no options at all.

The following patches fix up most in-tree filesystems, some have been
compile tested only, some have been reviewed and acked by the
maintainer.

262bf54144 aoe: user can ask driver to forget previously detected devices
When an AoE device is detected, the kernel is informed, and a new block device
is created.  If the device is unused, the block device corresponding to remote
device that is no longer available may be removed from the system by telling
the aoe driver to "flush" its list of devices.

Without this patch, software like GPFS and LVM may attempt to read from AoE
devices that were discovered earlier but are no longer present, blocking until
the I/O attempt times out.

Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
kernel.

This patch also adds board support for the ASB2303 with the ASB2308 daughter
board, and the ASB2305.  The only processor supported is the MN103E010, which
is an AM33v2 core plus on-chip devices.
