While unmapping an ODP writable page, the dirty bit of the page is set. In
order to do so, the head of the compound page is found.
Currently, the compound head is found even on non-writable pages, where it is
never used, leading to unnecessary cpu barrier that impacts performance.
This patch moves the search for the compound head to be done only when needed.

Currently, while mapping or unmapping pages for ODP, the umem mutex is locked
and unlocked once for each page. Such lock/unlock operation take few tens to
hundreds of nsecs. This makes a significant impact when mapping or unmapping few
MBs of memory.
To avoid this, the mutex should be locked only once per operation, and not per
page.

Currently the iw_cxgb4 implementation requires the qp and cq qid densities
to match as well as the qp and cq id ranges. So fail a device open if
the device configuration doesn't meet the requirements.
The reason for these restictions has to do with the fact that IQ qid X
has a UGTS register in the same bar2 page as EQ qid X. Thus both qids
need to be allocated to the same user process for security reasons.
The logic that does this (the qpid allocator in iw_cxgb4/resource.c)
handles this but requires the above restrictions.

A spinlock is regarded as contended when there is at least one waiter.
Currently, the code that checks whether there are any waiters rely on
tail value being greater than head. However, this is not true if tail
reaches the max value and wraps back to zero, so arch_spin_is_contended()
incorrectly returns 0 (not contended) when tail is smaller than head.
The original code (before regression) handled this case by casting the
(tail - head) to an unsigned value. This change simply restores that
behavior.

Normally if driver is busy to dispatch a request the logic is like below:
block layer: driver:
__blk_mq_run_hw_queue
a. blk_mq_stop_hw_queue
b. rq add to ctx->dispatch
later:
1. blk_mq_start_hw_queue
2. __blk_mq_run_hw_queue
But it's possible step 1-2 runs between a and b. And since rq isn't in
ctx->dispatch yet, step 2 will not run rq. The rq might get lost if
there are no subsequent requests kick in.

When a FUA request enters its DATA stage of flush pipeline, the
request is added to mq requeue list, the request will then be added to
ctx->rq_list. blk_mq_attempt_merge() might merge the request with a bio.
Later when the request is finished the flush pipeline, the
request->__data_len is 0. Then I only saw the bio gets endio called, the
original request never finish.
Adding REQ_FLUSH_SEQ into REQ_NOMERGE_FLAGS looks an easy fix.

The L3 Error handling on OMAP5 for the most part is very similar
to that of OMAP4, and had leveraged common data structures and
register layout definitions so far. Upon closer inspection, there
are a few minor differences causing an incorrect decoding and
reporting of the master NIU upon an error:
1. The L3_TARG_STDERRLOG_MSTADDR.STDERRLOG_MSTADDR occupies
11 bits on OMAP5 as against 8 bits on OMAP4, with the master
NIU connID encoded in the 6 MSBs of the STDERRLOG_MSTADDR
field.
2. The CLK3 FlagMux component has 1 input source on OMAP4 and 3
input sources on OMAP5. The common DEBUGSS source is at a
different input on each SoC.
Fix the above issues by using a OMAP5-specific compatible property
and using SoC-specific data where there are differences.

With commit bc078316d86c ("ARM: dts: DRA7: Add node for RTC"), we now
have AM57xx RTC register itself as alias 0 even before DS1307 or TPS
rtc drivers are loaded up. However, since neither TPS, nor AM57xx RTC
are capable of being backedup by battery, we would like to maintain
the "primary" rtc as mcp79410 rtc device.
This also generates the following warnings in the bootlog highlighting
the issue:
[ 5.895445] rtc-ds1307 2-006f: /aliases ID 0 not available

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.

If we use a combination of VMODE and I2C4 for retention modes,

Commit eec15edbb0e1 (ACPI / PNP: use device ID list for PNPACPI device
enumeration) changed the way how ACPI devices are enumerated and when
they are added to the PNP bus.
However, it broke the sound card support on (at least) a vintage
IBM ThinkPad 600E: with said commit applied, two of the necessary
"CSC01xx" devices are not added to the PNP bus and hence can not be
found during the initialization of the "snd-cs4236" module. As a
consequence, loading "snd-cs4236" causes null pointer exceptions.
The attached patch fixes the problem end re-enables sound on the
IBM ThinkPad 600E.

In commit 0b053c951829 ("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

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

bf35706f3d09 ("ARM: 8314/1: replace PROCINFO embedded branch with
relative offset") broke booting for Kirkwood. The kernel would say:
Starting kernel ...
Uncompressing Linux... done, booting the kernel.
Error: unrecognized/unsupported processor variant (0x56251311).
Fix it by removing the extraneous .long __feroceon_setup from the
feroceon_proc_info macro.

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 22b3c181c6c324a46f71aae806d8ddbe61d25761 ("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.
