quincy: Fix the build for SC-05D

A acommit 578e0f7 by cyanogen caused quincy kernel not to compile for SC-05D targed.
This was due to reloaction of static void gsbi_qup_i2c_gpio_config definition. SC-05D, as well as the other targets, needs that function. Tested by yours truly.

SCSI: sd: Fix potential out-of-bounds access

commit 984f1733fcee3fbc78d47e26c5096921c5d9946a upstream.

This patch fixes an out-of-bounds error in sd_read_cache_type(), found
by Google's AddressSanitizer tool.  When the loop ends, we know that
"offset" lies beyond the end of the data in the buffer, so no Caching
mode page was found.  In theory it may be present, but the buffer size
is limited to 512 bytes.

crypto: api - Fix race condition in larval lookup

commit 77dbd7a95e4a4f15264c333a9e9ab97ee27dc2aa upstream.

crypto_larval_lookup should only return a larval if it created one.
Any larval created by another entity must be processed through
crypto_larval_wait before being returned.

Otherwise this will lead to a larval being killed twice, which
will most likely lead to a crash.

powerpc: Handle unaligned ldbrx/stdbrx

commit 230aef7a6a23b6166bd4003bfff5af23c9bd381f upstream.

Normally when we haven't implemented an alignment handler for
a load or store instruction the process will be terminated.

The alignment handler uses the DSISR (or a pseudo one) to locate
the right handler. Unfortunately ldbrx and stdbrx overlap lfs and
stfs so we incorrectly think ldbrx is an lfs and stdbrx is an
stfs.

This bug is particularly nasty - instead of terminating the
process we apply an incorrect fixup and continue on.

With more and more overlapping instructions we should stop
creating a pseudo DSISR and index using the instruction directly,
but for now add a special case to catch ldbrx/stdbrx.

xen-gnt: prevent adding duplicate gnt callbacks

commit 5f338d9001094a56cf87bd8a280b4e7ff953bb59 upstream.

With the current implementation, the callback in the tail of the list
can be added twice, because the check done in
gnttab_request_free_callback is bogus, callback->next can be NULL if
it is the last callback in the list. If we add the same callback twice
we end up with an infinite loop, were callback == callback->next.

Replace this check with a proper one that iterates over the list to
see if the callback has already been added.

ARM: PCI: versatile: Fix SMAP register offsets

commit 99f2b130370b904ca5300079243fdbcafa2c708b upstream.

The SMAP register offsets in the versatile PCI controller code were
all off by four.  (This didn't have any observable bad effects
because on this board PHYS_OFFSET is zero, and (a) writing zero to
the flags register at offset 0x10 has no effect and (b) the reset
value of the SMAP register is zero anyway, so failing to write SMAP2
didn't matter.)

usb: xhci: Disable runtime PM suspend for quirky controllers

commit c8476fb855434c733099079063990e5bfa7ecad6 upstream.

If a USB controller with XHCI_RESET_ON_RESUME goes to runtime suspend,
a reset will be performed upon runtime resume. Any previously suspended
devices attached to the controller will be re-enumerated at this time.
This will cause problems, for example, if an open system call on the
device triggered the resume (the open call will fail).

Note that this change is only relevant when persist_enabled is not set
for USB devices.

This patch should be backported to kernels as old as 3.0, that
contain the commit c877b3b2ad5cb9d4fe523c5496185cc328ff3ae9 "xhci: Add

The client was in the middle of trying to send a frame when the
server->ssocket pointer got zeroed out. In most places, that we access
that pointer, the srv_mutex is held. There's only one spot that I see
that the server->ssocket pointer gets set and the srv_mutex isn't held.
This patch corrects that.

In dt282x_ai_insn_read() we call this macro like:

Because the if statement doesn't have curly braces it means we always

rculist: list_first_or_null_rcu() should use list_entry_rcu()

commit c34ac00caefbe49d40058ae7200bd58725cebb45 upstream.

list_first_or_null() should test whether the list is empty and return
pointer to the first entry if not in a RCU safe manner.  It's broken
in several ways.

* It compares __kernel @__ptr with __rcu @__next triggering the
  following sparse warning.

  net/core/dev.c:4331:17: error: incompatible types in comparison expression (different address spaces)

* It doesn't perform rcu_dereference*() and computes the entry address
  using container_of() directly from the __rcu pointer which is
  inconsitent with other rculist interface.  As a result, all three
  in-kernel users - net/core/dev.c, macvlan, cgroup - are buggy.  They
  dereference the pointer w/o going through read barrier.

* While ->next dereference passes through list_next_rcu(), the
  compiler is still free to fetch ->next more than once and thus
  nullify the "__ptr != __next" condition check.

Fix it by making list_first_or_null_rcu() dereference ->next directly
using ACCESS_ONCE() and then use list_entry_rcu() on it like other
rculist accessors.

v2: Paul pointed out that the compiler may fetch the pointer more than
    once nullifying the condition check.  ACCESS_ONCE() added on
    ->next dereference.

v3: Restored () around macro param which was accidentally removed.
    Spotted by Paul.
