ENGR00286273-2 misc: sram: Set default alignment to 4KbytesAs Kernel 3.0.35 does, we set the default iram alignment to 4Kbytes,
although it would waste few memory space.We here try to do this as an expediency because currently we couldn't
find a perfect solution for 4Kbytes alignment requirement from SDMA.Signed-off-by: Nicolin Chen

commit d5f8e166c25750adc147b0adf64a62a91653438a upstream.
pm_runtime_autosuspend can take synchronous or asynchronous
paths, Because we are calling pm_runtime_mark_last_busy just before
this most of the cases it takes the asynchronous way. However,
when the FW or driver resets during already running runtime suspend,
the call will result in calling to the driver's rpm callback and results
in a deadlock on device_lock.
The simplest fix is to replace pm_runtime_autosuspend with
asynchronous pm_request_autosuspend.Signed-off-by: Alexander Usyskin

This change consists of two changes:
1) If vmci_doorbell_create is called when neither guest nor
host personality as been initialized, vmci_get_context_id
will return VMCI_INVALID_ID. In that case, we should fail
the create call.
2) In doorbell destroy, we assume that vmci_guest_code_active()
has the same return value on create and destroy. That may not
be the case, so we may end up with the wrong refcount.
Instead, destroy should check explicitly whether the doorbell
is in the index table as an indicator of whether the guest
code was active at create time.Reviewed-by: Adit Ranadive

When interrupting an application which was allocating DMAable
memory, it was possible, that the DMA memory was deallocated
twice, leading to the error symptoms below.Thanks to Gerald, who analyzed the problem and provided this
patch.I agree with his analysis of the problem: ddcb_cmd_fixups() ->
genwqe_alloc_sync_sgl() (fails in f/lpage, but sgl->sgl != NULL
and f/lpage maybe also != NULL) -> ddcb_cmd_cleanup() ->
genwqe_free_sync_sgl() (double free, because sgl->sgl != NULL and
f/lpage maybe also != NULL)In this scenario we would have exactly the kind of double free that
would explain the WARNING / Bad page state, and as expected it is
caused by broken error handling (cleanup).Using the Ubuntu git source, tag Ubuntu-4.4.0-33.52, he was able to reproduce
the "Bad page state" issue, and with the patch on top he could not reproduce
it any more.------------[ cut here ]------------

SEC registers are not accessible when the TXE device is in low power
state, hence the SEC interrupt cannot be processed if device is not
awake.In some rare cases entrance to low power state (aliveness off) and input
ready bits can be signaled at the same time, resulting in communication
stall as input ready won't be signaled again after waking up. To resolve
this IPC_HHIER_SEC bit in HHISR_REG should not be cleaned if the
interrupt is not processed.Cc: stable@vger.kernel.org

This patch prevents resetting the cxl adapter via sysfs in presence of
one or more active cxl_context on it. This protects against an
unrecoverable error caused by PSL owning a dirty cache line even after
reset and host tries to touch the same cache line. In case a force reset
of the card is required irrespective of any active contexts, the int
value -1 can be stored in the 'reset' sysfs attribute of the card.The patch introduces a new atomic_t member named contexts_num inside
struct cxl that holds the number of active context attached to the card
, which is checked against '0' before proceeding with the reset. To
prevent against a race condition where a context is activated just after
reset check is performed, the contexts_num is atomically set to '-1'
after reset-check to indicate that no more contexts can be activated on
the card anymore.Before activating a context we atomically test if contexts_num is
non-negative and if so, increment its value by one. In case the value of
contexts_num is negative then it indicates that the card is about to be
reset and context activation is error-ed out at that point.Fixes: 62fa19d4b4fd ("cxl: Add ability to reset the card")

If the capi link is going down while the PSL owns a dirty cache line,
any access from the host for that data could lead to an Uncorrectable
Error.So when resetting the capi adapter through sysfs, make sure the PSL
cache is flushed. It won't help if there are any active Process
Elements on the card, as the cache would likely get new dirty cache
lines immediately, but if resetting an idle adapter, it should avoid
any bad surprises from data left over from terminated Process Elements.Signed-off-by: Frederic Barrat

CURRENT_TIME macro is not appropriate for filesystems as it
doesn't use the right granularity for filesystem timestamps.
Use current_time() instead.CURRENT_TIME is also not y2038 safe.
This is also in preparation for the patch that transitions
vfs timestamps to use 64 bit time and hence make them
y2038 safe. As part of the effort current_time() will be
extended to do range checks. Hence, it is necessary for all
file system timestamps to use current_time(). Also,
current_time() will be transitioned along with vfs to be
y2038 safe.Note that whenever a single call to current_time() is used
to change timestamps in different inodes, it is because they
share the same time granularity.Signed-off-by: Deepa Dinamani

Genwqe uses dma_alloc_coherent and depends on zero initialized memory. On
one occasion it ueses an explicit memset on others it uses un-initialized
memory.This bug was covered because some archs actually return zero initialized
memory when using dma_alloc_coherent but this is by no means guaranteed.
Simply switch to dma_zalloc_coherent.Signed-off-by: Sebastian Ott

The stall timer worker checks periodically if there is a stalled i/o
transaction. The issue with the current implementation is that the timer
is ticking also when there is no pending i/o transaction.
This patch provides a simple change that prevents rescheduling
of the delayed work when there is no pending i/o.Cc: Andy Lutomirski

When set_sl_ops() is called, the adapter data structure is not fully
initialized yet. Therefore the device name is not showing up in the
trace. Fix is simply to get the device name from the pci_dev
structure.Fixes: 6d382616ac22 ("cxl: Abstract the differences between the PSL and XSL")

The hardened usercopy is now consistently avoiding checks against const
sizes, since we really only want to perform runtime bounds checking
on lengths that weren't known at build time. To test the hardened usercopy
code, we must force the length arguments to be seen as non-const.Signed-off-by: Kees Cook

Pull char/misc driver fixes from Greg KH:
"Here are a number of small driver fixes for 4.8-rc5.The largest thing here is deleting an obsolete driver,
drivers/misc/bh1780gli.c, as the functionality of it was replaced by
an iio driver a while ago.The other fixes are things that have been reported, or reverts of
broken stuff (the binder change). All of these changes have been in
linux-next for a while with no reported issues"* tag 'char-misc-4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc:
thunderbolt: Don't declare Falcon Ridge unsupported
thunderbolt: Add support for INTEL_FALCON_RIDGE_2C controller.

The EG20T has 4 UART blocks. The clock source for the UART block is
configured to receive a clock from an external pin by default.An internal 25MHz clock in the EG20T can also be used as a clock source
for the clock.The MIPS based Boston platform ties the external clock pin down and relies
on the internal clock source for the UART to function.Boston is based on device tree.
Add a quirk to allow Boston to be detected via device tree and set the
correct clock source for UART.Signed-off-by: Zubair Lutfullah Kakakhel
