* 'urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/wfg/writeback:
don't busy retry the inode on failed grab_super_passive()

This fixes a soft lockup on conditions
a) the flusher is working on a work by __bdi_start_writeback(), while
b) someone else calls writeback_inodes_sb*() or sync_inodes_sb(), which
grab sb->s_umount and enqueue a new work for the flusher to execute
The s_umount grabbed by (b) will fail the grab_super_passive() in (a).
Then if the inode is requeued, wb_writeback() will busy retry on it.
As a result, wb_writeback() loops for ever without releasing
wb->list_lock, which further blocks other tasks.
Fix the busy loop by redirtying the inode. This may undesirably delay
the writeback of the inode, however most likely it will be picked up
soon by the queued work by writeback_inodes_sb*(), sync_inodes_sb() or
even writeback_inodes_wb().

Adding support for external power change notification. One problem found
is that there is a lag time before the sensor will return a new status.
To ensure that we only fire off the power_supply_changed event when the
status returned from the sensor is actually different, we delay sending
the the notification, and instead poll on it looking for a change. The
amount of time to poll is configurable via platform data.

IA32-Intel Devel guide Volume 3A - 14.3.2.1
-------------------------------------------
...
Opportunistic processor performance operation can be disabled by setting bit 38 of
IA32_MISC_ENABLES. This mechanism is intended for BIOS only. If
IA32_MISC_ENABLES[38] is set, CPUID.06H:EAX[1] will return 0.
Better detect things via cpuid, this cleans up the code a bit
and the MSR parts were not working correctly anyway.

This adds the last piece missing from turbostat (if called with -v).
It shows on Intel machines supporting Turbo Boost how many cores
have to be active/idle to enter which boost mode (frequency).
Whether the HW really enters these boost modes can be verified via
./cpupower monitor.

CPU power consumption vs performance tuning is no longer
limited to CPU frequency switching anymore: deep sleep states,
traditional dynamic frequency scaling and hidden turbo/boost
frequencies are tied close together and depend on each other.
The first two exist on different architectures like PPC, Itanium and
ARM, the latter (so far) only on X86. On X86 the APU (CPU+GPU) will
only run most efficiently if CPU and GPU has proper power management
in place.
Users and Developers want to have *one* tool to get an overview what
their system supports and to monitor and debug CPU power management
in detail. The tool should compile and work on as many architectures
as possible.
Once this tool stabilizes a bit, it is intended to replace the
Intel-specific tools in tools/power/x86

This is needed to match wireless cards with Intersil firmware that have
ID 0x0156:0x0002 and the third ID "Version 01.02". Such cards are
currently matched by orinoco_cs, which doesn't support WPA. They should
be matched by hostap_cs.
The first and the second product ID vary widely, so there are few users
with some particular IDs. Of those, very few can submit a patch for
hostap_cs or write a useful bugreport. It's still important to support
their hardware properly.
With PCMCIA_DEVICE_MANF_CARD_PROD_ID3, it should be possible to cover
the remaining Intersil based designs that kept the numeric ID and the
"version" of the reference design.

Several vendors implement a second configuration register, which we
check during device detection. Refactor the code to avoid duplication.

With a device ID register value of 0, the SA56004 detection is rather
weak. Check several other register too to confirm the detection, as we
do for other supported devices.

The optional extended local temperature register can never have
address 0, as this address is already used by another register. Thus
we can get rid of flag LM90_HAVE_LOCAL_EXT and simply rely on
reg_local_ext being non-zero to determine if a given chip has this
extension or not. This makes the code more simple.
