When processing a fork event, the tools lookup the parent thread by its

That can happen if the data is being processed out of order, or if the

Assume the latter case, print a dump message, remove the erroneous
thread, create a new one with the correct pid, and keep going.

Due to how async_tx behaves internally, having more XOR channels than
CPUs is actually hurting performance more than it improves it, because
memcpy requests get scheduled on a different channel than the XOR
requests, but async_tx will still wait for the completion of the
memcpy requests before scheduling the XOR requests.
It is in fact more efficient to have at most one channel per CPU,
which this patch implements by limiting the number of channels per
engine, and the number of engines registered depending on the number
of availables CPUs.
Marvell platforms are currently available in one CPU, two CPUs and
four CPUs configurations:
- in the configurations with one CPU, only one channel from one
engine is used.
- in the configurations with two CPUs, only one channel from each
engine is used (they are two XOR engines)
- in the configurations with four CPUs, both channels of both engines
are used.

The only reason why we had dmacap,* properties is because back when
DMA_MEMSET was supported, only one out of the two channels per engine
could do a memset operation. But this is something that the driver
already knows anyway, and since then, the DMA_MEMSET support has been
removed.
The driver is already well aware of what each channel supports and the
one to one mapping between Linux specific implementation details (such
as dmacap,interrupt enabling DMA_INTERRUPT) and DT properties is a
good indication that these DT properties are wrong.
Therefore, this commit simply gets rid of these dmacap,* properties,
they are now ignored, and the driver is responsible for knowing the
capabilities of the hardware with regard to the dmaengine subsystem
expectations.

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:
IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN
For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

In Kconfig, definitions of options take the following form:
"<COMMAND> <PARAM> <PARAM> ...". COMMANDs and PARAMs are treated
slightly different by the underlying parser.
While commit 2e0d737fc7 ("kconfig: don't silently ignore unhandled
characters") introduced a warning for unsupported characters around
PARAMs, it does not cover situations where a COMMAND has additional
characters before it.
This change makes Kconfig emit a warning if superfluous characters
are found before COMMANDs. As the 'help' statement sometimes is
written as '---help---', the '-' character would now also be regarded
as unhandled and generate a warning. To avoid that, '-' is added to
the list of allowed characters, and the token '---help---' is included
in the zconf.gperf file.

With the removal of the dynamic reallocation of page tables for

The page table free code can now use the alloc_pgste bit in the
mm context to decide if a page table is 2K or 4K, there is no mix
of different sized page tables anymore. This eliminates the need
to use "page->_mapcount == 0" to check for 4K page table.
Use the lower two bits in page->_mapcount to indicate which
2K fragments of the 4K page are in use.
As 31-bit support is gone, remove the two defines ALLOC_ORDER
and FRAG_MASK and use the constants directly where appropriate.
