When we umount f2fs, we need to avoid long delay due to discard commands, which
is actually taking tens of seconds, if storage is very slow on UNMAP. So, this
patch introduces timeout-based work on it. In addition to discard commands, we
can also do GC during the given time period.
By default,

The MFD_QCOM_RPM is the RPM in family A, but the rpmpd driver only implements
support for SMD based devices. Drop the dependency and remove includes of the
family A headers. No functional change.

Counter values for per-channel interrupts and ring buffer full

The busses on SDM845 provides 36 address bits, extend the address and
size cells to make it possible to describe this in "ranges" and
"dma-ranges".
While touching all reg properties, addresses are padded to 8 digits.

Changes since v3:
- Split out
For devices attached to an IOMMU, translation between IOVA and physical
addresses is no longer 1:1 and dma-ranges should be specified to
describe the available IOVA address space.
On SDM845 the busses are implemented with 36 address bits, so dma-ranges
must be defined to reduce the size of the
These patches extends the size cells of the soc bus and define the dma-ranges,
so that DMA allocations for devices with IOMMU attached will get valid IOVAs.

- Split patch in two
- Rewrote commit message from scratch

In Kbuild, if_changed and friends must have FORCE as a prerequisite.
Hence, $(filter-out FORCE,$^) or $(filter-out $(PHONY),$^) is a common
pattern to get the names of all the prerequisites except phony targets.
Add real-prereqs as a shorthand.
Note:
We cannot replace $(filter %.o,$^) in

All the callers of size_append pass $(filter-out FORCE,$^).
Move $(filter-out FORCE,$^) to the definition of size_append.
This makes the callers cleaner because $(call ...) can be omitted

Fixed. Thanks for spotting it, Stephen.

spmi-gpio did not have any irqchip support so consumers of this in
device tree would need to call gpio[d]_to_irq() in order to get the
proper IRQ on the underlying PMIC. IRQ chips in device tree should
be usable from the start without the consumer having to make an
additional call to get the

Patch introduced in v4.
Add interrupt controller properties now that spmi-gpio is a proper
hierarchical IRQ chip. The interrupts property is no longer needed so
remove it.
This change was not tested on any hardware but the same change was
tested on qcom-pm8941.dtsi using a LG Nexus 5 (hammerhead) phone with
no issues.
This patchset improves several overlapping issues around stale TLB
entries and W^X violations. It is combined from a slightly tweaked

the "Don’t leave executable TLB entries to freed pages v2" [2]

There is no apparent reason not to use text_poke_early() while we are

be the case of jump-labels, so do so.

text_mutex is currently expected to be held before text_poke() is
called, but we kgdb does not take the mutex, and instead *supposedly*

The reason for the "supposedly" comment

Sometimes we want to set a temporary page-table entries (PTEs) in one of

There are only two types of poking: early and breakpoint based. The use
of a function pointer to perform poking complicates the code and is
probably inefficient due to the use of indirect branches.

Since alloc_module() will not set the pages as executable soon, we need
to do so for ftrace trampoline pages after they are allocated.
For the time being, we do not change ftrace to use the text_poke()
interface. As a result, ftrace breaks still breaks W^X.

In the face of missing user notification support, the self test needs
to stop executing a test (ASSERT_*) instead of just reporting and
continuing (EXPECT_*). This adjusts the user notification tests to do
that where needed.

For architectures with CONFIG_ARCH_HAS_SET_ALIAS, pages can be unmapped
