32d317c60e mmc: remove MMC bus legacy suspend/resume method
MMC bus is using legacy suspend/resume method, which is not compatible if
runtime pm callbacks are used. In this scenario, MMC bus suspend/resume
callbacks cannot be called when system entering S3. So change to use the
new defined dev_pm_ops for system sleeping mode.

Tested on AM335x Platform. Solves major issue/crash reported at
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg65425.html

6be5ceb02e VM: add "vm_mmap()" helper function
This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.

This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c.  But that way we don't have
to export our internal do_mmap_pgoff() function.

Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead.  We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

4d048f915f mmc: omap_hsmmc: Get rid of of_have_populated_dt() usage
of_have_populated_dt() is not expected to be used in drivers but
instead only in early platform init code.
Drivers on the other hand should rely on dev->of_node or of_match_device().
Besides usage of of_have_populated_dt() also throws up build error as below
which was reported by Balaji TK, when omap_hsmmc is built as a module.

ERROR: "allnodes" [drivers/mmc/host/omap_hsmmc.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

So get rid of all of_have_populated_dt() usage in omap_hsmmc driver and
instead use dev->of_node to make the same dicisions as earlier.

283028122d mmc: fixes for eMMC v4.5 sanitize operation
eMMC v4.5 sanitize operation erases all copies of unmapped
data.  However trim or erase operations must be used first
to unmap the required sectors.  That was not being done.

Fixes apply to linux 3.2 on.

7194efb8f0 mmc: fixes for eMMC v4.5 discard operation
eMMC v4.5 discard operation is significantly different from the
existing trim operation because it is not guaranteed to work with
the new sanitize operation.  Consequently mmc_can_trim() is
separated from mmc_can_discard().

Also the new discard operation does not result in the sectors being
set to all-zeros, so discard_zeroes_data must not be set.

In addition, the new discard has the same timeout as trim, but from
v4.5 trim is defined to use the hc timeout.  The timeout calculation
is adjusted accordingly.

Fixes apply to linux 3.2 on.

e4eb1ff61b VM: add "vm_brk()" helper function
It does the same thing as "do_brk()", except it handles the VM locking

It turns out that all external callers want that anyway, so we can make
do_brk() static to just mm/mmap.c while at it.

98a2139f4f nfs: Enclose hostname in brackets when needed in nfs_do_root_mount
When hostname contains colon (e.g. when it is an IPv6 address) it needs
to be enclosed in brackets to make parsing of NFS device string possible.
Fix nfs_do_root_mount() to enclose hostname properly when needed. NFS code
actually does not need this as it does not parse the string passed by
nfs_do_root_mount() but the device string is exposed to userspace in
/proc/mounts.

19244ad06b Revert "ACPI: ignore FADT reset-reg-sup flag"
This reverts commit cf450136bf.

It breaks reboot on at least one Thinkpad T43, as reported by Jörg Otte:
 "On reboot it shuts down as normal.
  The last lines displayed are:

  >Unmounting temporary filesystems.. [OK]
  >Deactivating swap...               [OK]
  >Unmounting local filesystems...    [OK]
  >Will now restart
  >    Restarting system

  Then I hear it accessing the cd-drive, but then it's being stuck."

Jörg bisected the regression to this commit.

That commit fixes another machine (see

  https://bugzilla.kernel.org/show_bug.cgi?id=11533

for details) that has a BIOS bug and doesn't support ACPI reset.
However, at least one of those other reporters no longer even has the
machine in question, and had a different workaround to begin with.
Besides, it clearly was a buggy BIOS.  Let's not break the correct case
to fix that case.

b3dc627cab memblock: memblock should be able to handle zero length operations
Commit 24aa07882b ("memblock, x86: Replace memblock_x86_reserve/
free_range() with generic ones") replaced x86 specific memblock
operations with the generic ones; unfortunately, it lost zero length
operation handling in the process making the kernel panic if somebody
tries to reserve zero length area.

There isn't much to be gained by being cranky to zero length operations
and panicking is almost the worst response.  Drop the BUG_ON() in
memblock_reserve() and update memblock_add_region/isolate_range() so
that all zero length operations are handled as noops.

If we have another thread (very likely) touched the list, we
end up hitting a problem "that the next element is wrong because
we should be able to cope with that. The problem is that the
next->next pointer would be set LIST_POISON1. " (Stefano's

8a95bc8dfe powerpc/85xx: don't call of_platform_bus_probe() twice
Commit 46d026ac ("powerpc/85xx: consolidate of_platform_bus_probe calls")
replaced platform-specific of_device_id tables with a single function
that probes the most of the busses in 85xx device trees.  If a specific
platform needed additional busses probed, then it could call
of_platform_bus_probe() again.  Typically, the additional platform-specific
busses are children of existing busses that have already been probed.
of_platform_bus_probe() does not handle those child busses automatically.

Unfortunately, this doesn't actually work.  The second (platform-specific)
call to of_platform_bus_probe() never finds any of the busses it's asked
to find.

To remedy this, the platform-specific of_device_id tables are eliminated,
and their entries are merged into mpc85xx_common_ids[], so that all busses
are probed at once.

3adadc08cc net ax25: Reorder ax25_exit to remove races.
While reviewing the sysctl code in ax25 I spotted races in ax25_exit
where it is possible to receive notifications and packets after already
freeing up some of the data structures needed to process those
notifications and updates.

Call unregister_netdevice_notifier early so that the rest of the cleanup
code does not need to deal with network devices.  This takes advantage
of my recent enhancement to unregister_netdevice_notifier to send
unregister notifications of all network devices that are current
registered.

Move the unregistration for packet types, socket types and protocol
types before we cleanup any of the ax25 data structures to remove the
possibilities of other races.

The MC77xx devices can operate in two modes: "Direct IP" or "QMI",
switchable using a password protected AT command.  Both product ID
and USB interface configuration will change when switched.

The "sierra_net" driver supports the "Direct IP" mode.  This driver
supports the "QMI" mode.

There are also multiple possible USB interface configurations in each
mode, some providing more than one wwan interface.  Like many other
devices made for Windows, different interface types are identified
using a static interface number.  We define a Sierra specific
interface whitelist to support this.

BX_E3B0_MAX_NUM_COS_PORT0 and max_num_of_cos is also
DCBX_E3B0_MAX_NUM_COS_PORT0.  In the original code
"pri == max_num_of_cos" was accepted but it is one past the end of the

Also we used "pri" before capping it.  It's a harmless read past the end
of the array, but it would affect which error message gets printed.

3066616ce2 xen/xenbus: Add quirk to deal with misconfigured backends.
A rather annoying and common case is when booting a PVonHVM guest
and exposing the PV KBD and PV VFB - as broken toolstacks don't
always initialize the backends correctly.

Normally The HVM guest is using the VGA driver and the emulated
keyboard for this (though upstream version of QEMU implements
PV KBD, but still uses a VGA driver). We provide a very basic
two-stage wait mechanism - where we wait for 30 seconds for all
devices, and then for 270 for all them except the two mentioned.

That allows us to wait for the essential devices, like network
or disk for the full 6 minutes.

To trigger this, put this in your guest config:

vfb = [ 'vnc=1, vnclisten=0.0.0.0 ,vncunused=1']

instead of this:
vnc=1
vnclisten="0.0.0.0"

ThinkPad 410,420,510,520 and X201 with cx50585 & co chips have the
docking-station ports, but BIOS doesn't initialize for these pins.
Thus, like the former X200, we need to set up the pins manually in the
driver.

The odd part is that the same PCI SSID is used for X200 and T400, thus
we need to prepare individual fixup tables for cx5051 and others.
