Alan Cox 4e2b1c4f56 x86/intel_mid: Kconfig select fix
If we select a symbol it should have a type declared first
otherwise in some situations the config tools get upset. They
are currently perhaps a bit too resilient which is why this
wasn't noticed initially.

Will Deacon 6bd054096d ARM: 7185/1: perf: don't assign platform_device on unsupported CPUs
In the unlikely case that a platform registers a PMU platform_device
when running on a CPU that is unsupported by perf, we will encounter a
NULL dereference when trying to assign the platform_device to the
cpu_pmu structure.

This patch checks that the CPU is supported by perf before assigning
the platform_device.

Takashi Iwai f1a73746c6 ALSA: hda - Fix GPIO LED setup for IDT 92HD75 codecs
Some HP laptops with IDT 92HD75 codecs may use a GPIO > 4 for the mute
LED, but currently the driver doesn't check this properly, and confuses
the mute LED behavior.  This ended up with the silent output  on some
HP laptops due to  having another GPIO used as external amp control.

This patch fixes the problem by checking the max GPIO count and
comparing with the given value from DMI entry instead of magic fixed
value 4 and 8, and adding a new field to indicate the VREF mute-LED
behavior.

Uwe Kleine-König de66a97901 ARM: 7187/1: fix unwinding for XIP kernels
The linker places the unwind tables in readonly sections. So when using
an XIP kernel these are located in ROM and cannot be modified.
For that reason the current approach to convert the relative offsets in
the unwind index to absolute addresses early in the boot process doesn't
work with XIP.

The offsets in the unwind index section are signed 31 bit numbers and
the structs are sorted by this offset. So it first has offsets between
0x40000000 and 0x7fffffff (i.e. the negative offsets) and then offsets
between 0x00000000 and 0x3fffffff. When seperating these two blocks the
numbers are sorted even when interpreting the offsets as unsigned longs.

So determine the first non-negative entry once and track that using the
new origin pointer. The actual bisection can then use a plain unsigned
long comparison. The only thing that makes the new bisection more
complicated is that the offsets are relative to their position in the
index section, so the key to search needs to be adapted accordingly in
each step.

Moreover several consts are added to catch future writes and rename the
member "addr" of struct unwind_idx to "addr_offset" to better match the
new semantic. (This has the additional benefit of breaking eventual
users at compile time to make them aware of the change.)

In my tests the new algorithm was a tad faster than the original and has
the additional upside of not needing the initial conversion and so saves
some boot time and it's possible to unwind even earlier.

Nicolas Pitre 974c07249b ARM: 7186/1: fix Kconfig issue with PHYS_OFFSET and !MMU
Commit 1b9f95f8ad (ARM: prepare for removal of a bunch of <mach/memory.h>
files) introduced CONFIG_PHYS_OFFSET but the Kconfig hex prompt did not
provide a default value.

This has the undesired side effect of breaking a reportedly used
trick for updating defconfigs on the fly for routine buildtesting
across all arch and all platforms, i.e.

	cp /path/to/somedefconfig .config ; yes "" | make oldconfig

because the config system will endlessly loop until a valid address is
provided.

However we can't just pick a random default value since it is likely to
be wrong for the majority of the boards as the right answer for this
option is quite varied.  So the fact that the config system insists on
having a proper value be entered is actually a good thing.

It turns out that only at91x40_defconfig has this problem because it has
CONFIG_MMU=n. However, in the !MMU case, there is already a CONFIG_DRAM_BASE
value that can be used here.  So let's use that as a default in that case
and suppress the redundant CONFIG_PHYS_OFFSET prompt.

Eventually the DRAM_BASE config option could simply be replaced by
PHYS_OFFSET directly, but that's a larger change better suited for later.

Sebastian Andrzej Siewior 65b0c78d5a target/rd: fix or rewrite the copy routine
So the code assumes that the sg list is only a array while in reality
loopback SGL memory via scsi_cmnd into target-core may be already
chained.  This patch converts ramdisk code to use sg_miter logic from
scatterlist.h in order to properly support passthrough SGL usage with
transport_generic_map_mem_to_cmd() via loopback.

With this patch the bug goes away. However after umount/mount of the
device my files are gone. So something is still not right. After looking
at it for a while I decided to rewrite the that part of the code and now
things do work for me.

This patch removes legacy usage of PYX_TRANSPORT_* return codes in a number
of locations and addresses cases where transport_generic_request_failure()
was returning the incorrect sense upon CHECK_CONDITION status after the
v3.1 converson to use errno return codes.

This includes the conversion of transport_generic_request_failure() to
process cmd->scsi_sense_reason and handle extra TCM_RESERVATION_CONFLICT
before calling transport_send_check_condition_and_sense() to queue up
response status.  It also drops PYX_TRANSPORT_OUT_OF_MEMORY_RESOURCES legacy
usgae, and returns TCM_LOGICAL_UNIT_COMMUNICATION_FAILURE w/ a response
for these cases.

transport_generic_allocate_tasks(), transport_generic_new_cmd(), backend
SCF_SCSI_DATA_SG_IO_CDB ->do_task(), and emulated ->execute_task() have
all been updated to set se_cmd->scsi_sense_reason and return errno codes
universally upon failure.  This includes cmd->scsi_sense_reason assignment
in target_core_alua.c, target_core_pr.c and target_core_cdb.c emulation code.

Finally it updates fabric modules to remove the legacy usage, and for
TFO->new_cmd_map() callers forwards return values outside of fabric code.
iscsi-target has also been updated to remove a handful of special cases
related to the cleanup and signaling QUEUE_FULL handling w/ ft_write_pending()

(v2: Drop extra SCF_SCSI_CDB_EXCEPTION check during failure from
     transport_generic_new_cmd, and re-add missing task->task_error_status
     assignment in transport_complete_task)
