587823d39f gpiolib: check for parent device in devprop_gpiochip_set_names() 
It's possible for a GPIO chip to not have a parent device (whose
properties we inspect for 'gpio-line-names'). In this case we should
simply return from devprop_gpiochip_set_names(). Add an appropriate
check for this use-case.

7cba1a4d5e gpiolib: generalize devprop_gpiochip_set_names() for device properties 
devprop_gpiochip_set_names() is overly complicated with taking the
fwnode argument (which requires using dev_fwnode() & of_fwnode_handle()
in ACPI and OF GPIO code respectively). Let's just switch to using the
generic device properties.

This allows us to pull the code setting line names directly into
gpiochip_add_data_with_key() instead of handling it separately for
ACPI and OF.

8d4a85b6ab gpiolib: switch to simpler IDA interface 
We don't need to specify any ranges when allocating IDs so we can switch
to ida_alloc() and ida_free() instead of the ida_simple_ counterparts.

ida_simple_get(ida, 0, 0, gfp) is equivalent to
ida_alloc_range(ida, 0, UINT_MAX, gfp) which is equivalent to
ida_alloc(ida, gfp). Note: IDR will never actually allocate an ID
larger than INT_MAX.

0ea683931a gpio: dwapb: Convert driver to using the GPIO-lib-based IRQ-chip 
GPIO-lib provides a ready-to-use interface to initialize an IRQ-chip on
top of a GPIO chip. It's better from maintainability and readability
point of view to use one instead of supporting a hand-written Generic
IRQ-chip-based implementation. Moreover the new implementation won't
cause much functional overhead but will provide a cleaner driver code.
All of that makes the DW APB GPIO driver conversion pretty much justified
especially seeing a tendency of the other GPIO drivers getting converted
too.

Here is what we do in the framework of this commit to convert the driver
to using the GPIO-lib-based IRQ-chip interface:

1) IRQ ack, mask and unmask callbacks are locally defined instead of
using the Generic IRQ-chip ones.

2) An irq_chip structure instance is embedded into the dwapb_gpio
private data. Note we can't have a static instance of that structure since
GPIO-lib will add some hooks into it by calling gpiochip_set_irq_hooks().
A warning about that would have been printed by the GPIO-lib code if we
used a single irq_chip structure instance for multiple DW APB GPIO
controllers.

3) Initialize the gpio_irq_chip structure embedded into the gpio_chip
descriptor. By default there is no IRQ enabled so any event raised will be
handled by the handle_bad_irq() IRQ flow handler. If DW APB GPIO IP-core
is synthesized to have non-shared reference IRQ-lines, then as before the
hierarchical and cascaded cases are distinguished by checking how many
parental IRQs are defined. (Note irq_set_chained_handler_and_data() won't
initialize IRQs, which descriptors couldn't be found.) If DW APB GPIO IP
is used on a platform with shared IRQ line, then we simply won't let the
GPIO-lib to initialize the parental IRQs, but will handle them locally in
the driver.

4) Discard linear IRQ-domain and Generic IRQ-chip initialization, since
GPIO-lib IRQ-chip interface will create a new domain and accept a standard
IRQ-chip structure pointer based on the setting we provided in the
gpio_irq_chip structure.

5) Manually select a proper IRQ flow handler directly in the
irq_set_type() callback by calling irq_set_handler_locked() method, since
an ordinary (not Generic) irq_chip descriptor is now utilized. Note this
shalln't give any regression

6) Alter CONFIG_GPIO_DWAPB kernel config to select
CONFIG_GPIOLIB_IRQCHIP instead of CONFIG_GENERIC_IRQ_CHIP.

Note neither 4) nor 5) shall cause a regression of commit 6a2f4b7dad
("gpio: dwapb: use a second irq chip"), since the later isn't properly
used here anyway.

7569486d79 gpio: dwapb: Add ngpios DT-property support 
Indeed generic GPIO DT-schema implies that number of GPIOs should be
described by the "ngpios" property located under a GPIO-provider DT node.
In that case it's redundant to have a vendor-specific "snps,nr-gpios"
property describing the same setting. Moreover it might be errors prone.

Since commit 93d2e4322a ("of: platform: Batch fwnode parsing when adding
all top level devices") the fwnode parsing is resumed after the vast
majority of the platform devices are added. Implicitly that commit
activates re-parsing of the whole device tree GPIOs-phandle properties
detected having "-gpio/-gpios" suffixes. Since the vendor-specific number
of GPIOs property is defined with "-gpios" suffix, then of_link_property()
will consider it as a suffix-property with "#gpio-cells" structure, which
obviously it doesn't have. As a result for two DW APB GPIO controllers
we'll have the next errors printed.

OF: /bus@1f059000/gpio@1f044000/gpio-port@0: could not find phandle
OF: /bus@1f059000/gpio@1f045000/gpio-port@0: could not get #gpio-cells for /opp-table
OF: /bus@1f059000/gpio@1f044000/gpio-port@0: could not find phandle
OF: /bus@1f059000/gpio@1f045000/gpio-port@0: could not get #gpio-cells for /opp-table

See, the kernel fwnode parsing procedure even tried to resolve the phandle
ID, which it thought was the opp-table DT-node, while in fact it was just
a number "32". What would happen if that magic number actually referred to
a GPIO DT-node with "#gpio-cells" property defined?..

In order to fix the problem let's mark the "snps,nr-gpios" property as
deprecated and add the generic "ngpios" property support with the same
purpose as the deprecated one. That and the errors log above shall
motivate the platform developer to convert the DW APB GPIO DT-nodes to
using the standard number of GPIOs property.

pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for

GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and

d84835b118 A RISC-V Fix for 5.9 
I collected a single fix during the merge window: we managed to break the early
 trap setup on !MMU, this patch fixes it.
 
 The power keeps going on here so I haven't have a chance to give this the
 testing I usually would, but I don't have a Kendryte anyway so I doubt I'd pick
 up anything subtle even if I was to test.  The patch seems pretty safe and it's
 still early, so I don't see any reason to let it sit around.
 
 It's fairly late so if it misses the merge window that's not a big deal.  I'll
 definately have stuff for next week, so I'll just start from whenever this
 lands.

One case was missed in the short IO retry handling, and that's hitting
-EAGAIN on a blocking attempt read (eg from io-wq context). This is a
problem on sockets that are marked as non-blocking when created, they
don't carry any REQ_F_NOWAIT information to help us terminate them
instead of perpetually retrying.

d4e7cd36a9 io_uring: sanitize double poll handling 
There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.

Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().

Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.

713eee8472 perf tools changes for v5.9: 2nd batch 
Fixes:
 
 - Fixes for 'perf bench numa'.
 
 - Always memset source before memcpy in 'perf bench mem'.
 
 - Quote CC and CXX for their arguments to fix build in environments using
   those variables to pass more than just the compiler names.
 
 - Fix module symbol processing, addressing regression detected via "perf test".
 
 - Allow multiple probes in record+script_probe_vfs_getname.sh 'perf test' entry.
 
 Improvements:
 
 - Add script to autogenerate socket family name id->string table from copy of
   kernel header, used so far in 'perf trace'.
 
 - 'perf ftrace' improvements to provide similar options for this utility so
   that one can go from 'perf record', 'perf trace', etc to 'perf ftrace' just
   by changing the name of the subcommand.
 
 - Prefer new "sched:sched_waking" trace event when it exists in 'perf sched'
   post processing.
 
 - Update POWER9 metrics to utilize other metrics.
 
 - Fall back to querying debuginfod if debuginfo not found locally.
 
 Miscellaneous:
 
 - Sync various kvm headers with kernel sources.
 
 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
 
 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.
 
 fedora:rawhide with python3 and gcc 10.1.1-2 is failing (10.1.1-1 on fedora:32
 works), fixes will be provided soon.
 
 clearlinux:latest is failing on libbpf, there is a fix already in the bpf tree.

Merge tag 'perf-tools-2020-08-14' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull more perf tools updates from Arnaldo Carvalho de Melo:
 "Fixes:
   - Fixes for 'perf bench numa'.

   - Always memset source before memcpy in 'perf bench mem'.

   - Quote CC and CXX for their arguments to fix build in environments
     using those variables to pass more than just the compiler names.

   - Fix module symbol processing, addressing regression detected via
     "perf test".

   - Allow multiple probes in record+script_probe_vfs_getname.sh 'perf
     test' entry.

  Improvements:
   - Add script to autogenerate socket family name id->string table from
     copy of kernel header, used so far in 'perf trace'.

   - 'perf ftrace' improvements to provide similar options for this
     utility so that one can go from 'perf record', 'perf trace', etc to
     'perf ftrace' just by changing the name of the subcommand.

   - Prefer new "sched:sched_waking" trace event when it exists in 'perf
     sched' post processing.

   - Update POWER9 metrics to utilize other metrics.

   - Fall back to querying debuginfod if debuginfo not found locally.

  Miscellaneous:
   - Sync various kvm headers with kernel sources"
