af1d486c18 x86 / platform / hp_wmi: Fix bluetooth_rfkill misuse in hp_wmi_rfkill_setup()

c218c713c5 parport_pc: disable PARPORT_PC_SUPERIO on parisc architecture
If enabled, CONFIG_PARPORT_PC_SUPERIO scans on PC-like hardware for
various super-io chips by accessing i/o ports in a range which will
crash any parisc hardware at once.

In addition, parisc has it's own incompatible superio chip
(CONFIG_SUPERIO), so if we disable PARPORT_PC_SUPERIO completely for
parisc we can avoid that people by accident enable the parport_pc
superio option too.

   parisc/PCI: lba: convert to pci_create_root_bus() for correct root bus
                    resources

  Supply root bus resources to pci_create_root_bus() so they're correct
  immediately.  This fixes the problem of "early" and "header" quirks seeing
  incorrect root bus resources.

added tests for elmmio_space.start while it should use
elmmio_space.flags.  This for example led to incorrect resource
assignments and a non-working stifb framebuffer on most parisc machines.

LBA 10:1: PCI host bridge to bus 0000:01
pci_bus 0000:01: root bus resource [io  0x12000-0x13fff] (bus address [0x2000-0x3fff])
pci_bus 0000:01: root bus resource [mem 0xfffffffffa000000-0xfffffffffbffffff] (bus address [0xfa000000-0xfbffffff])
pci_bus 0000:01: root bus resource [mem 0xfffffffff4800000-0xfffffffff4ffffff] (bus address [0xf4800000-0xf4ffffff])
pci_bus 0000:01: root bus resource [??? 0x00000001 flags 0x0]

8b811bae69 s390/dasd: fix handling of gone paths
When a path is gone and dasd_generic_path_event is called with a
PE_PATH_GONE event, we must assume that any I/O request on that
subchannel is still running. This is unlike the dasd_generic_notify
handler and the CIO_NO_PATH event, which implies that the subchannel
has been cleared.
If dasd_generic_path_event finds that the path has been the last
usable path, it must not call dasd_generic_last_path_gone (which would
reset the state of running requests), but just set the
DASD_STOPPED_DC_WAIT bit.

John W. Linville says:

====================
Please pull this batch of fixes intended for the 3.10 stream...

Regarding the NFC bits, Samuel says:

"This is the first batch of NFC fixes for 3.10, and it contains:

- 3 fixes for the NFC MEI support:
        * We now depend on the correct Kconfig symbol.
        * We register an MEI event callback whenever we enable an NFC device,
          otherwise we fail to read anything after an enable/disable cycle.
        * We only disable an MEI device from its disable mey_phy_ops,
          preventing useless consecutive disable calls.

- An NFC Makefile cleanup, as I forgot to remove a commented out line when
  moving the LLCP code to the NFC top level directory."

As for the mac80211 bits, Johannes says:

"This time I have a fix from Stanislaw for a stupid mistake I made in the
auth/assoc timeout changes, a fix from Felix for 64-bit traffic counters
and one from Helmut for address mask handling in mac80211. I also have a
few fixes myself for four different crashes reported by a few people."

And Johannes says this about the iwlwifi bit:

"This fixes a brown paper-bag bug that we really should've caught in
review. More details in the changelog for the fix."

On top of that...

Arend van Spriel and Hante Meuleman cooperate to send a series of AP
and P2P mode fixes for brcmfmac.

Gabor Juhos corrects a register offset for AR9550, avoiding a bus
error.

Dan Carpenter provides a fixup to some dmesg output in the atmel
driver.

And, finally...

Felix Fietkau not only gives us a trio of small AR934x fixes, but
also refactors the ath9k aggregation session start/stop handling
(using the generic mac80211 support) in order to avoid a deadlock.

Please let me know if there are problems!

aafc9d158b iscsi-target: Fix iscsit_free_cmd() se_cmd->cmd_kref shutdown handling
With the introduction of target_get_sess_cmd() referencing counting for
ISCSI_OP_SCSI_CMD processing with iser-target, iscsit_free_cmd() usage
in traditional iscsi-target driver code now needs to be aware of the
active I/O shutdown case when a remaining se_cmd->cmd_kref reference may
exist after transport_generic_free_cmd() completes, requiring a final
target_put_sess_cmd() to release iscsi_cmd descriptor memory.

This patch changes iscsit_free_cmd() to invoke __iscsit_free_cmd() before
transport_generic_free_cmd() -> target_put_sess_cmd(), and also avoids
aquiring the per-connection queue locks for typical fast-path calls
during normal ISTATE_REMOVE operation.

Also update iscsit_free_cmd() usage throughout iscsi-target to
use the new 'bool shutdown' parameter.

This patch fixes a regression bug introduced during v3.10-rc1 in
commit 3e1c81a95, that was causing the following WARNING to appear:

Go ahead and propigate up the ->cmd_kref put return value from
target_put_sess_cmd() -> transport_release_cmd() -> transport_put_cmd()

This is useful for certain fabrics when determining the active I/O

cea4dcfdad iscsi-target: fix heap buffer overflow on error
If a key was larger than 64 bytes, as checked by iscsi_check_key(), the
error response packet, generated by iscsi_add_notunderstood_response(),
would still attempt to copy the entire key into the packet, overflowing
the structure on the heap.

Remote preauthentication kernel memory corruption was possible if a
target was configured and listening on the network.

This patch fixes a bug where FILEIO was incorrectly reporting the number

It changes fd_get_blocks() to follow all other backend ->get_blocks() cases,

number of bytes, and also fixes initial fd_block_size assignment at
fd_configure_device() time introduced in commit 0fd97ccf4.

37448adfc7 aerdrv: Move cper_print_aer() call out of interrupt context
The following warning was seen on 3.9 when a corrected PCIe error was being
handled by the AER subsystem.

WARNING: at .../drivers/pci/search.c:214 pci_get_dev_by_id+0x8a/0x90()

This occurred because a call to pci_get_domain_bus_and_slot() was added to
cper_print_pcie() to setup for the call to cper_print_aer().  The warning
showed up because cper_print_pcie() is called in an interrupt context and
pci_get* functions are not supposed to be called in that context.

The solution is to move the cper_print_aer() call out of the interrupt
context and into aer_recover_work_func() to avoid any warnings when calling
pci_get* functions.

1d19f7800d ib_srpt: Call target_sess_cmd_list_set_waiting during shutdown_session
Given that srpt_release_channel_work() calls target_wait_for_sess_cmds()
to allow outstanding se_cmd_t->cmd_kref a change to complete, the call
to perform target_sess_cmd_list_set_waiting() needs to happen in
srpt_shutdown_session()

Also, this patch adds an explicit call to srpt_shutdown_session() within
srpt_drain_channel() so that target_sess_cmd_list_set_waiting() will be
called in the cases where TFO->shutdown_session() is not triggered
directly by TCM.

9b31a328e3 target: Re-instate sess_wait_list for target_wait_for_sess_cmds
Switch back to pre commit 1c7b13fe652 list splicing logic for active I/O
shutdown with tcm_qla2xxx + ib_srpt fabrics.

The original commit was done under the incorrect assumption that it's safe to
walk se_sess->sess_cmd_list unprotected in target_wait_for_sess_cmds() after
sess->sess_tearing_down = 1 has been set by target_sess_cmd_list_set_waiting()
during session shutdown.

So instead of adding sess->sess_cmd_lock protection around sess->sess_cmd_list
during target_wait_for_sess_cmds(), switch back to sess->sess_wait_list to
allow wait_for_completion() + TFO->release_cmd() to occur without having to
walk ->sess_cmd_list after the list_splice.

Also add a check to exit if target_sess_cmd_list_set_waiting() has already
been called, and add a WARN_ON to check for any fabric bug where new se_cmds
are added to sess->sess_cmd_list after sess->sess_tearing_down = 1 has already
been set.

419e321df8 clk: vt8500: Fix unbalanced spinlock in vt8500_dclk_set_rate()
With the addition of a DVO clock, a bug is now evident in the vt8500
clock code:
[    0.290000] WARNING: at init/main.c:698 do_one_initcall+0x158/0x18c()
[    0.300000] initcall wm8505fb_driver_init+0x0/0xc returned with disabled int

This is caused by an unbalanced spinlock in vt8500_dclk_set_rate().
Replace the second call to spin_lock_irqsave() with spin_unlock_irqrestore().

6532cb71fb clk: si5351: Set initial clkout rate when defined in platform data.
clock-frequency property from platform data was read but never used.
Apply defined rate when clock is registered.

67e1e2268e clk: si5351: Fix clkout rate computation.
Rate was incorrectly computed because we read from wrong divider register.

8d0b8801c9 xenbus_client.c: correct exit path for xenbus_map_ring_valloc_hvm
Apparently we should not free page that has not been allocated.
This is b/c alloc_xenballooned_pages will take care of freeing
the page on its own.
