26f5ae865d MIPS: Netlogic: Fix UP compilation on XLR
The commit 2a37b1a "MIPS: Netlogic: Move from u32 cpumask to cpumask_t"
breaks uniprocessor compilation on XLR with:

arch/mips/netlogic/xlr/setup.c: In function 'prom_init':
arch/mips/netlogic/xlr/setup.c:196:6: error: unused variable 'i'

Fix by defining 'i' only when CONFIG_SMP is defined.

fe950df700 MIPS: AR71xx: Fix AR71XX_PCI_MEM_SIZE
The base address of the PCI memory is 0x10000000 and the base address of the
PCI configuration space is 0x17000000 on the AR71xx SoCs.

The AR71XX_PCI_MEM_SIZE is defined as 0x08000000 which is wrong because that
overlaps with the configuration space.  This patch fixes the value of the
AR71XX_PCI_MEM_SIZE constant, in order to avoid this resource conflicts.

e0094244e4 samsung-laptop: Disable on EFI hardware
It has been reported that running this driver on some Samsung laptops
with EFI can cause those machines to become bricked as detailed in the
following report,

	https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557

There have also been reports of this driver causing Machine Check
Exceptions on recent EFI-enabled Samsung laptops,

	https://bugzilla.kernel.org/show_bug.cgi?id=47121

So disable it if booting from EFI since this driver relies on
grovelling around in the BIOS memory map which isn't going to work.

83e6818974 efi: Make 'efi_enabled' a function to query EFI facilities
Originally 'efi_enabled' indicated whether a kernel was booted from
EFI firmware. Over time its semantics have changed, and it now
indicates whether or not we are booted on an EFI machine with
bit-native firmware, e.g. 64-bit kernel with 64-bit firmware.

The immediate motivation for this patch is the bug report at,

    https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557

which details how running a platform driver on an EFI machine that is
designed to run under BIOS can cause the machine to become
bricked. Also, the following report,

    https://bugzilla.kernel.org/show_bug.cgi?id=47121

details how running said driver can also cause Machine Check
Exceptions. Drivers need a new means of detecting whether they're
running on an EFI machine, as sadly the expression,

    if (!efi_enabled)

hasn't been a sufficient condition for quite some time.

Users actually want to query 'efi_enabled' for different reasons -
what they really want access to is the list of available EFI
facilities.

For instance, the x86 reboot code needs to know whether it can invoke
the ResetSystem() function provided by the EFI runtime services, while
the ACPI OSL code wants to know whether the EFI config tables were
mapped successfully. There are also checks in some of the platform
driver code to simply see if they're running on an EFI machine (which
would make it a bad idea to do BIOS-y things).

This patch is a prereq for the samsung-laptop fix patch.

8a7d7cbf7b mwifiex: fix incomplete scan in case of IE parsing error
A scan request is split into multiple scan commands queued in
scan_pending_q. Each scan command will be sent to firmware and
its response is handlded one after another.

If any error is detected while parsing IE in command response
buffer the remaining data will be ignored and error is returned.

We should check if there is any more scan commands pending in
the queue before returning error. This ensures that we will call
cfg80211_scan_done if this is the last scan command, or send
next scan command in scan_pending_q to firmware.

a2f95c3637 regulator: clear state each invocation of of_regulator_match
of_regulator_match() saves some dynamcially allocated state into the
match table that's passed to it. By implementation and not contract, for
each match table entry, if non-NULL state is already present,
of_regulator_match() will not overwrite it. of_regulator_match() is
typically called each time a regulator is probe()d. This means it is
called with the same match table over and over again if a regulator
triggers deferred probe. This results in stale, kfree()d data being left
in the match table from probe to probe, which causes a variety of crashes
or use of invalid data.

Explicitly free all output state from of_regulator_match() before
generating new results in order to avoid this.

8b4b0dcbf7 target: Fix zero-length READ_CAPACITY_16 regression
This patch fixes a regression introduced in v3.8-rc1 code where a
zero-length READ_CAPACITY_16 was no longer returning GOOD status, but
instead returning TCM_LOGICAL_UNIT_COMMUNICATION_FAILURE to generate
a CHECK_CONDITION status.

This regression was introduced with the following commit:

  commit de103c93af
  Author: Christoph Hellwig <hch@lst.de>
  Date:   Tue Nov 6 12:24:09 2012 -0800

      target: pass sense_reason as a return value

and this patch has been tested with the following zero-length CDB:

  sg_raw /dev/sdd 9e 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00
  SCSI Status: Good

  Sense Information:
  sense buffer empty

Also, convert sbc_emulate_readcapacity() to follow the same method
of handling transport_kmap_data_sg() return values, but we never
expect a zero-length request here.

nmk_prcm_gpiocr_get_mode is only needed for debugfs output at

Functions called from a driver probe() method must not be

Without this patch, building exynos_defconfig results in

The function exynos5440_pinctrl_probe() references

This is often because exynos5440_pinctrl_probe lacks a __init

6cdd20c380 vmxnet3: set carrier state properly on probe
vmxnet3 fails to set netif_carrier_off on probe, meaning that when an interface
is opened the __LINK_STATE_NOCARRIER bit is already cleared, and so
/sys/class/net/<ifname>/operstate remains in the unknown state.  Correct this by
setting netif_carrier_off on probe, like other drivers do.

Also, while we're at it, lets remove the netif_carrier_ok checks from the
link_state_update function, as that check is atomically contained within the
netif_carrier_[on|off] functions anyway

Tested successfully by myself

286003048a e1000e: enable ECC on I217/I218 to catch packet buffer memory errors
In rare instances, memory errors have been detected in the internal packet
buffer memory on I217/I218 when stressed under certain environmental
conditions.  Enable Error Correcting Code (ECC) in hardware to catch both
correctable and uncorrectable errors.  Correctable errors will be handled
by the hardware.  Uncorrectable errors in the packet buffer will cause the
packet to be received with an error indication in the buffer descriptor
causing the packet to be discarded.  If the uncorrectable error is in the
descriptor itself, the hardware will stop and interrupt the driver
indicating the error.  The driver will then reset the hardware in order to
clear the error and restart.

Both types of errors will be accounted for in statistics counters.

9e85722d58 tuntap: allow polling/writing/reading when detached
We forbid polling, writing and reading when the file were detached, this may
complex the user in several cases:

- when guest pass some buffers to vhost/qemu and then disable some queues,
  host/qemu needs to do its own cleanup on those buffers which is complex
  sometimes. We can do this simply by allowing a user can still write to an
  disabled queue. Write to an disabled queue will cause the packet pass to the
  kernel and read will get nothing.
- align the polling behavior with macvtap which never fails when the queue is
  created. This can simplify the polling errors handling of its user (e.g vhost)

We can simply achieve this by don't assign NULL to tfile->tun when detached.

2b8b328b61 vhost_net: handle polling errors when setting backend
Currently, the polling errors were ignored, which can lead following issues:

- vhost remove itself unconditionally from waitqueue when stopping the poll,
  this may crash the kernel since the previous attempt of starting may fail to
  add itself to the waitqueue
- userspace may think the backend were successfully set even when the polling
  failed.

Solve this by:

- check poll->wqh before trying to remove from waitqueue
- report polling errors in vhost_poll_start(), tx_poll_start(), the return value
  will be checked and returned when userspace want to set the backend

After this fix, there still could be a polling failure after backend is set, it
will addressed by the next patch.

a13d310471 netem: fix delay calculation in rate extension
The delay calculation with the rate extension introduces in v3.3 does
not properly work, if other packets are still queued for transmission.
For the delay calculation to work, both delay types (latency and delay
introduces by rate limitation) have to be handled differently. The
latency delay for a packet can overlap with the delay of other packets.
The delay introduced by the rate however is separate, and can only
start, once all other rate-introduced delays finished.

Latency delay is from same distribution for each packet, rate delay
depends on the packet size.

.: latency delay
-: rate delay
x: additional delay we have to wait since another packet is currently
   transmitted

  .....----                    Packet 1
    .....xx------              Packet 2
               .....------     Packet 3
    ^^^^^
    latency stacks
         ^^
         rate delay doesn't stack
               ^^
               latency stacks

  -----> time

When a packet is enqueued, we first consider the latency delay. If other
packets are already queued, we can reduce the latency delay until the
last packet in the queue is send, however the latency delay cannot be
<0, since this would mean that the rate is overcommitted.  The new
reference point is the time at which the last packet will be send. To
find the time, when the packet should be send, the rate introduces delay
has to be added on top of that.

80d84ef3ff l2tp: prevent l2tp_tunnel_delete racing with userspace close
If a tunnel socket is created by userspace, l2tp hooks the socket destructor
in order to clean up resources if userspace closes the socket or crashes.  It
also caches a pointer to the struct sock for use in the data path and in the
netlink interface.

While it is safe to use the cached sock pointer in the data path, where the
skb references keep the socket alive, it is not safe to use it elsewhere as
such access introduces a race with userspace closing the socket.  In
particular, l2tp_tunnel_delete is prone to oopsing if a multithreaded
userspace application closes a socket at the same time as sending a netlink
delete command for the tunnel.

This patch fixes this oops by forcing l2tp_tunnel_delete to explicitly look up
a tunnel socket held by userspace using sockfd_lookup().

739701888f x86, efi: remove attribute check from setup_efi_pci
It looks like the original commit that copied the rom contents from
efi always copied the rom, and the fixup in setup_efi_pci from commit
886d751a2e ("x86, efi: correct precedence of operators in
setup_efi_pci") broke that.

This resulted in macbook pro's no longer finding the rom images, and
thus not being able to use the radeon card any more.

The solution is to just remove the check for now, and always copy the
rom if available.

For non-snoop mode, we fiddle with the page attributes of CORB/RIRB

that the current code blindly assumes that the buffer is contiguous.
However, the ring buffers may be SG-buffers, thus a wrong vmapped

546eda4bca m68k: Provide dma_mmap_coherent() and dma_get_sgtable()
m68k/allmodconfig:

drivers/media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_mmap’:
drivers/media/v4l2-core/videobuf2-dma-contig.c:204: error: implicit declaration of function ‘dma_mmap_coherent’
drivers/media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_get_base_sgt’:
drivers/media/v4l2-core/videobuf2-dma-contig.c:387: error: implicit declaration of function ‘dma_get_sgtable’

For architectures using dma_map_ops, dma_mmap_coherent() and
dma_get_sgtable() are provided in <asm-generic/dma-mapping-common.h>.

M68k does not use dma_map_ops, hence it should implement them as inline
stubs using dma_common_mmap() and dma_common_get_sgtable().
