16882c1e96 sched: fix TASK_WAKEKILL vs SIGKILL race
schedule() has the special "TASK_INTERRUPTIBLE && signal_pending()" case,
this allows us to do

	current->state = TASK_INTERRUPTIBLE;
	schedule();

without fear to sleep with pending signal.

However, the code like

	current->state = TASK_KILLABLE;
	schedule();

is not right, schedule() doesn't take TASK_WAKEKILL into account. This means
that mutex_lock_killable(), wait_for_completion_killable(), down_killable(),
schedule_timeout_killable() can miss SIGKILL (and btw the second SIGKILL has
no effect).

Introduce the new helper, signal_pending_state(), and change schedule() to
use it. Hopefully it will have more users, that is why the task's state is
passed separately.

Note this "__TASK_STOPPED | __TASK_TRACED" check in signal_pending_state().
This is needed to preserve the current behaviour (ptrace_notify). I hope
this check will be removed soon, but this (afaics good) change needs the
separate discussion.

The fast path is "(state & (INTERRUPTIBLE | WAKEKILL)) + signal_pending(p)",
basically the same that schedule() does now. However, this patch of course
bloats schedule().

148f1678f0 [S390] sparsemem: use SPARSEMEM_STATIC if !64BIT.
In case of !64BIT kernel we end up with a zero sized mem_section array.
This happens because NR_MEM_SECTIONS is smaller than SECTIONS_PER_ROOT
but we have:

#define NR_SECTION_ROOTS (NR_MEM_SECTIONS / SECTIONS_PER_ROOT)

and

struct mem_section *mem_section[NR_SECTION_ROOTS];

So fix this by selecting SPARSEMEM_STATIC which makes sure
that SECTIONS_PER_ROOT is 1.

5f0c4a3cb6 tg3: Fix 5761 WOL
On 5761 non-e devices, two problems prevent the administrator from
overriding the WOL settings in the device's NVRAM.

The first problem is that GPIO 0 and GPIO 2 have been swapped.  This
change prevented the administrator from turning on WOL when it is
disabled in NVRAM.  The fix is to add a new path for the 5761 that
swaps the two GPIOs in the code as well.

The second problem is that GPIO 1 could not be toggled by the driver
because the GPIO is shared with the debug UART GPIO.  This will prevent
the administrator from being able to turn WOL off if it was enabled in
NVRAM.  The fix is to always disable the debug UART after a GRC reset.

2bd3ed0479 tg3: Fix 5714S / 5715S / 5780S link failures
The git commit ef167e2703 entitled
"Fix supporting flowctrl code" introduced a bug that prevents 5714S,
5715S and 5780S devices from falling back to a forced link mode.  The
problem is that the added flow control check will always fail if flow
control is set to autoneg and either RX or TX (or both) flow control
is enabled.  The driver defaults to setting flow control to autoneg
and advertises both RX and TX flow control.

The fix is to remove the errant check.

56fa18e8f1 power_supply: Fix race in power_supply_uevent
Commit 54d29ad33e (Power Supply: fix race
in device_create) introduced a race in power_supply_uevent. Previously it
checked that power_supply is available by checking for dev->driver_data.
But now dev->driver_data is set before power_supply->dev is initialised.

be038b3764 mac80211: Checking IBSS support while changing channel in ad-hoc mode
This patch adds a check to the set_channel flow. When attempting to change
the channel while in IBSS mode, and the new channel does not support IBSS
mode, the flow return with an error value with no consequences on the

872ba53395 mac80211: decrease IBSS creation latency
Sufficient scans (at least 2 or 3) should have been done within 7
seconds to find an existing IBSS to join.  This should improve IBSS
creation latency; and since IBSS merging is still in effect, shouldn't
have detrimental effects on eventual IBSS convergence.

a01f545040 libertas: fix sleep confirmation
This fixes an issus that made "iwconfig eth1 power on" non-working.
When we get a "PS sleep" event, we have to confirm this to the firmware.
The confirm happens with a command, but this command is special: the
firmware won't send us a response. if_cs_host_to_card() is setting
priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and
was never cleared back.

Now I put the special knowledge that the CMD_802_11_PS_MODE with
CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly
clearing the dnld_sent state in lbs_send_confirmsleep().

ea177305b3 ipw2200: queue direct scans
When another scan is in progress, a direct scan gets dropped on the
floor.  However, that direct scan is usually the scan that's really
needed by userspace, and gets stomped on by all the broadcast scans the
ipw2200 driver issues internally.  Make sure the direct scan happens
eventually, and as a bonus ensure that the passive scan worker is
cleaned up when appropriate.

The change of request_passive_scan form a struct work to struct
delayed_work is only to make the set_wx_scan() code a bit simpler, it's
still only used with a delay of 0 to match previous behavior.

Minor source code cleanup of page flags in mm/page_alloc.c.
Move the definition of the groups of bits to page-flags.h.

The purpose of this clean up is that the next patch will
conditionally add a page flag to the groups.  Doing that
in a header file is cleaner than adding #ifdefs to the
C code.

d5791d13b1 Fix invalid access errors in blk_lookup_devt
Commit 30f2f0eb4b ("block: do_mounts -
accept root=<non-existant partition>") extended blk_lookup_devt() to be
able to look up partitions that had not yet been registered, but in the
process made the assumption that the '&block_class.devices' list only
contains disk devices and that you can do 'dev_to_disk(dev)' on them.

That isn't actually true.  The block_class device list also contains the
partitions we've discovered so far, and you can't just do a
'dev_to_disk()' on those.

So make sure to only work on devices that block/genhd.c has registered
itself, something we can test by checking the 'dev->type' member.  This
makes the loop in blk_lookup_devt() match the other such loops in this
file.

[ We may want to do an alternate version that knows to handle _either_
  whole-disk devices or partitions, but for now this is the minimal fix
  for a series of crashes reported by Mariusz Kozlowski in

	http://lkml.org/lkml/2008/5/25/25
