Add an ->enter_freeze callback routine, acpi_idle_enter_freeze(), to
the ACPI cpuidle driver and point ->enter_freeze to it for all the
C2-type and C3-type states that don't need to fall back to C1
(which may be halt-induced and that will re-enable interrupts on
exit from idle, which ->enter_freeze cannot do).

The efficiency of suspend-to-idle depends on being able to keep CPUs
in the deepest available idle states for as much time as possible.
Ideally, they should only be brought out of idle by system wakeup
interrupts.
However, timer interrupts occurring periodically prevent that from
happening and it is not practical to chase all of the "misbehaving"
timers in a whack-a-mole fashion. A much more effective approach is
to suspend the local ticks for all CPUs and the entire timekeeping
along the lines of what is done during full suspend, which also
helps to keep suspend-to-idle and full suspend reasonably similar.
The idea is to suspend the local tick on each CPU executing
cpuidle_enter_freeze() and to make the last of them suspend the
entire timekeeping. That should prevent timer interrupts from
triggering until an IO interrupt wakes up one of the CPUs. It
needs to be done with interrupts disabled on all of the CPUs,
though, because otherwise the suspended clocksource might be
accessed by an interrupt handler which might lead to fatal
consequences.
Unfortunately, the existing ->enter callbacks provided by cpuidle
drivers generally cannot be used for implementing that, because some
of them re-enable interrupts temporarily and some idle entry methods
cause interrupts to be re-enabled automatically on exit. Also some
of these callbacks manipulate local clock event devices of the CPUs
which really shouldn't be done after suspending their ticks.
To overcome that difficulty, introduce a new cpuidle state callback,
->enter_freeze, that will be guaranteed (1) to keep interrupts
disabled all the time (and return with interrupts disabled) and (2)
not to touch the CPU timer devices. Modify cpuidle_enter_freeze() to
look for the deepest available idle state with ->enter_freeze present
and to make the CPU execute that callback with suspended tick (and the
last of the online CPUs to execute it with suspended timekeeping).

Theoretically, ktime_get_mono_fast_ns() may be executed after
timekeeping has been suspended (or before it is resumed) which
in turn may lead to undefined behavior, for example, when the
clocksource read from timekeeping_get_ns() called by it is
not accessible at that time.
Prevent that from happening by setting up a dummy readout base for
the fast timekeeper during timekeeping_suspend() such that it will
always return the same number of cycles.
After the last timekeeping_update() in timekeeping_suspend() the
clocksource is read and the result is stored as cycles_at_suspend.
The readout base from the current timekeeper is copied onto the
dummy and the ->read pointer of the dummy is set to a routine
unconditionally returning cycles_at_suspend. Next, the dummy is
passed to update_fast_timekeeper().
Then, ktime_get_mono_fast_ns() will work until the subsequent
timekeeping_resume() and the proper readout base for the fast
timekeeper will be restored by the timekeeping_update() called
right after clearing timekeeping_suspended.

The tpm_ibmvtpm module is affected by an unaligned access problem.
ibmvtpm_crq_get_version failed with rc=-4 during boot when vTPM is
enabled in Power partition, which supports both little endian and
big endian modes.
We added little endian support to fix this problem:
1) added cpu_to_be64 calls to ensure BE data is sent from an LE OS.
2) added be16_to_cpu and be32_to_cpu calls to make sure data received

Ignacy reported that when eth0 is down and add a vlan device
on top of it like:
ip link add link eth0 name eth0.1 up type vlan id 1
We will get a refcount leak:
unregister_netdevice: waiting for eth0.1 to become free. Usage count = 2
The problem is when rtnl_configure_link() fails in rtnl_newlink(),
we simply call unregister_device(), but for stacked device like vlan,
we almost do nothing when we unregister the upper device, more work
is done when we unregister the lower device, so call its ->dellink().

If during transmission system error was returned, the logic was to
incorrectly deduce that chip is a TPM 1.x chip. This patch fixes this
issue. Also, this patch changes probing so that message tag is used as the
measure for TPM 2.x, which should be much more stable. A separate function
called tpm2_probe() is encapsulated because it can be used with any
chipset.

Fixed suspend/resume paths for TPM 2.0 and consolidated all the
associated code to the tpm_pm_suspend() and tpm_pm_resume()
functions. Resume path should be handled by the firmware, i.e.
Startup(CLEAR) for hibernate and Startup(STATE) for suspend.
There might be some non-PC embedded devices in the future where
Startup() is not the handled by the FW but fixing the code for
those IMHO should be postponed until there is hardware available
to test the fixes although extra Startup in the driver code is
essentially a NOP.
Added Shutdown(CLEAR) to the remove paths of TIS and CRB drivers.
Changed tpm2_shutdown() to a void function because there isn't
much you can do except print an error message if this fails with
a system error.
Fixes: aec04cbdf723 ("tpm: TPM 2.0 FIFO Interface")
Fixes: 30fc8d138e91 ("tpm: TPM 2.0 CRB Interface")
[phuewe: both did send TPM_Shutdown on resume which 'disables' the TPM
and did not send TPM2_Shutdown on teardown which leads some TPM2.0 to
believe there was an attack (no TPM2_Shutdown = no orderly shutdown =
attack)]

The Broadcom firmware files are named with firmware version information
encoded into lmp_subver field. So BCM20702B0_002.001.014.0527.0607.hex
would be represented by 0x410e. To allow for an easier decoding of the
actual firmware names, provide an internal table that does the mapping
and request the firmware file by name.
Bluetooth: hci0: BCM20702B0 (002.001.014) build 0607
Now the complicated encoding of lmp_subver will be decoded and turned
into the name and firmware version information from the firmware files.
The previous attempt of using udev->product failed badly since it never
contains any matching entry to the actual hardware or firmware files
distributed by Broadcom in their Windows drivers. It is even worse since
it can change depending on if the internal bootstrapping happened before
the USB bus enumeration or after. This caused many race conditions.

NAND-tree is used to check wiring between MAC and PHY using NAND gates
on the PHY side, hence the name.
NAND-tree initial status is latched at reset by probing the IRQ pin.
However some devices are sharing the PHY IRQ pin with other peripherals
such as Atmel SAMA5D[34]x-EK boards when using the optional TM7000
display module, therefore they are switching the PHY in NAND-tree test
mode depending on the current IRQ line status at reset.
This patch ensure PHY is not in NAND-tree test mode for all Micrel PHYs
using IRQ line as a NAND-tree toggle mode at reset.

dynamic metrics allocation from inetpeer. The assumption breaks
when ndisc discovered router with RTAX_MTU and RTAX_HOPLIMIT metric.
Refer to ndisc_router_discovery() in ndisc.c and note that dst_metric_set()
is called after the route is created.
This patch creates the metrics array (by calling dst_cow_metrics_generic) in
ipv6_cow_metrics().
Test:
radvd.conf:
interface qemubr0
{
AdvLinkMTU 1300;
AdvCurHopLimit 30;
prefix fd00:face:face:face::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr off;
};
};
Before:
[root@qemu1 ~]# ip -6 r show | egrep -v unreachable
fd00:face:face:face::/64 dev eth0 proto kernel metric 256 expires 27sec
fe80::/64 dev eth0 proto kernel metric 256
default via fe80::74df:d0ff:fe23:8ef2 dev eth0 proto ra metric 1024 expires 27sec
After:
[root@qemu1 ~]# ip -6 r show | egrep -v unreachable
fd00:face:face:face::/64 dev eth0 proto kernel metric 256 expires 27sec mtu 1300
fe80::/64 dev eth0 proto kernel metric 256 mtu 1300
default via fe80::74df:d0ff:fe23:8ef2 dev eth0 proto ra metric 1024 expires 27sec mtu 1300 hoplimit 30

There is a capability which let the hw could change the settings
automatically when the power change to ON. However, the USB reset
would reset the settings to the hw default, so the driver has to
restore the relative settings. Otherwise, it would influence the
functions of the hw, and the compatibility for the USB hub and
USB host controller.
The relative settings are as following.
- set the power down scale to 96.
- enable the power saving function of USB 2.0.
- disable the ALDPS of ECM mode.
- set burst mode depending on the burst size.
- enable the flow control of endpoint full.
- set fifo empty boundary to 32448 bytes.
- enable the function of exiting LPM when Rx OK occurs.
- set the connect timer to 1.

Commit 4f579ae7de56 (ext4: fix punch hole on files with indirect
mapping) rewrote FALLOC_FL_PUNCH_HOLE for ext4 files with indirect
mapping. However, there are bugs in several corner cases. This fixes 5
distinct bugs:
1. When there is at least one entire level of indirection between the
start and end of the punch range and the end of the punch range is the
first block of its level, we can't return early; we have to free the
intervening levels.
2. When the end is at a higher level of indirection than the start and
ext4_find_shared returns a top branch for the end, we still need to free
the rest of the shared branch it returns; we can't decrement partial2.
3. When a punch happens within one level of indirection, we need to
converge on an indirect block that contains the start and end. However,
because the branches returned from ext4_find_shared do not necessarily
start at the same level (e.g., the partial2 chain will be shallower if
the last block occurs at the beginning of an indirect group), the walk
of the two chains can end up "missing" each other and freeing a bunch of
extra blocks in the process. This mismatch can be handled by first
making sure that the chains are at the same level, then walking them
together until they converge.
4. When the punch happens within one level of indirection and
ext4_find_shared returns a top branch for the start, we must free it,
but only if the end does not occur within that branch.
5. When the punch happens within one level of indirection and
ext4_find_shared returns a top branch for the end, then we shouldn't
free the block referenced by the end of the returned chain (this mirrors
the different levels case).

This patch adds the device shutdown routine for Intel Bluetooth device.
Some platforms have BT LED issue with Intel Bluetooth device that BT LED goes
off 5 seconds after BT is turned off
For Intel Bluetooth device, the BT LED is turned off when:
- there is no active connection or radio activity
- USB is suspend
So, when the BT is turned off, it takes 5 seconds because USB suspend timeone
is 5 seconds by default. And if the USB suspend is not enabled, BT LED won't be
turned off.
To fix this issue, recently Intel Bluetooth firmware patch had been submitted
to turn off the BT LED immediately by the vendor specific command(0xFC3F). And
this patch sends this command to the device before closing the device.
For backward compatibility of this command with old firmware, this command was
supported before, but it behaves same as HCI_RESET internally. So, it won't be
the problem even if the system doesn't have the latest firmware patch.
