The interrupt polarity provided in devicetree is used to configure
the interrupt controller(ARM GIC), however, it seems that we have an
inverter at the GIC boundary inside AM57xx which inverts the signal
input from sys_irq external interrupt source.
Further, as per GIC distributor TRM,
http://infocenter.arm.com/help/topic/com.arm.doc.ddi0438d/BGBHIACJ.html#BABJFCFB
ARM GIC distributor does not support IRQ trigger type
IRQ_TYPE_LEVEL_LOW, and only rising or level high signals.
However, for some reason, the current configuration(which gets ignored
by GIC driver) functions on some platforms, however, on few platforms
results in infinite interrupts hogging the system down.
Switch over to rising edge for GIC configuration which is also aligned
with trigger point from the RTC chip and the internal inversion.

For the sake of forgetful clients, the server should return the layouts
to the file system on 'last close' of a file (assuming that there are no
delegations outstanding to that particular client) or on delegreturn
(assuming that there are no opens on a file from that particular
client).
In theory the information is all there in current data structures, but
it's not efficiently available; nfs4_file->fi_ref includes references on
the file across all clients, but we need a per-(client, file) count.
Walking through lots of stateid's to calculate this on each close or
delegreturn would be painful.
This patch introduces infrastructure to maintain per-client opens and
delegation counters on a per-file basis.

Commit df52699e4f ("NFSv4.1: Don't cache deviceids that have no

behavior is stupid and the language around this area in rfc5661 is a
mess carified by an errata that I submittted, Trond insists on this
behavior. Not caching deviceids degrades block layout performance
massively as a GETDEVICEINFO is fairly expensive.

If we use a combination of VMODE and I2C4 for retention modes,
eventually the off idle power consumption will creep up by about

Let's fix the issue by adding i2c_cfg_clear_mask for the bits

In commit 0b053c9518 ("lib: memzero_explicit: use barrier instead
of OPTIMIZER_HIDE_VAR"), we made memzero_explicit() more robust in
case LTO would decide to inline memzero_explicit() and eventually
find out it could be elimiated as dead store.
While using barrier() works well for the case of gcc, recent efforts
from LLVMLinux people suggest to use llvm as an alternative to gcc,
and there, Stephan found in a simple stand-alone user space example
that llvm could nevertheless optimize and thus elimitate the memset().
A similar issue has been observed in the referenced llvm bug report,
which is regarded as not-a-bug.
Based on some experiments, icc is a bit special on its own, while it
doesn't seem to eliminate the memset(), it could do so with an own
implementation, and then result in similar findings as with llvm.
The fix in this patch now works for all three compilers (also tested
with more aggressive optimization levels). Arguably, in the current
kernel tree it's more of a theoretical issue, but imho, it's better
to be pedantic about it.
It's clearly visible with gcc/llvm though, with the below code: if we
would have used barrier() only here, llvm would have omitted clearing,
not so with barrier_data() variant:
static inline void memzero_explicit(void *s, size_t count)
{
memset(s, 0, count);
barrier_data(s);
}
int main(void)
{
char buff[20];
memzero_explicit(buff, sizeof(buff));
return 0;
}

As gcc, clang, but also icc defines __GNUC__, it's sufficient to define
this in compiler-gcc.h only to be picked up. For a fallback or otherwise
unsupported compiler, we define it as a barrier. Similarly, for ecc which
does not support gcc inline asm.

That patch is solving a non-existant problem while creating a

When we unhash it the name space must be the same as the one

rdma_conn_param private data is copied using memcpy after headers such
as cma_hdr (see cma_resolve_ib_udp as example). so the start of the
private data is aligned to the end of the structure that come before. if
this structure end with u32 the meaning is that the start of the private
data will be 4 bytes aligned. structures that use u8/u16/u32/u64 are
naturally aligned but in case the structure start is not 8 bytes aligned,
all u64 members of this structure will not be aligned. to solve this issue
we must use special macros that allow unaligned access to those
unaligned members.

This comes from a confusion of what should be the minimal backlog. It is
pretty clear it is not 64KB or whatever max GSO packet ever reached the
qdisc.
codel intent was to use MTU of the device.
After the fix, we finally drop some packets, and rtt/cwnd of my single

With commit 9fd85eb502 ("ARM: pmu: add support for interrupt-affinity
property"), we print a warning when we find a PMU SPI with a missing
missing interrupt-affinity property in a pmu node. Unfortunately, we
pass the wrong (NULL) device node to of_node_full_name, resulting in
unhelpful messages such as:
hw perfevents: Failed to parse <no-node>/interrupt-affinity[0]
This patch fixes the name to that of the pmu node.

PPIs are affine by nature, so the interrupt-affinity property is not
used and therefore we shouldn't print a warning in its absence.

The block could never be compiled; CPU_ICACHE_STREAMING_DISABLE has not
been defined in Kconfig since the very first Git commit. Hence, we can
safely remove the entire block.

CPU_ARM1020_CPU_IDLE is not defined in Kconfig. The last reference on
LKML dates back to 2001, so we can safely remove the comments to make
static analysis tools happy.

Patch 22b3c181c6 ("arm: dma-mapping: limit
IOMMU mapping size") added a check for IO address space size. However
this patch broke IOMMU initialization for typical platforms initialized
from device tree, which get the default IO address space size of 4GiB.
This value doesn't fit into size_t and fails a check introduced by that
commit resulting in failed dma-mapping/iommu initialization. This patch
fixes this issue by adding proper support for full 4GiB address space
size.

Do not use ieee80211_vif pointer in ath_get_rate_txpower() since it has been
overwritten by setup_frame_info() and it will result in a corrupted tx power
configuration. Set per-packet tx power in setup_frame_info() according to
current vif tx power.

This is three logical fixes (as 5 patches). The 3ware class of drivers were
causing an oops with multiqueue by tearing down the command mappings after
completing the command (where the variables in the command used to tear down
the mapping were no-longer valid). There's also a fix for the qnap iscsi
target which was choking on us sending it commands that were too long and a
fix for the reworked aha1542 allocating GFP_KERNEL under a lock.

Lenovo G40-30 does not provide any physical radio switch to user.
Therefore disable the rfkill switch identically to the Yoga 2 approach.
(Note for later, models ids are sorted alphabetically).
Benefit is to make wireless available again without unloading module.
It was tested successfully on 4.1.0-rc1 base with this model:
(LENOVO_MT_80FY_BU_idea_FM_Lenovo G40-30).
