Commit 49d9e77e72cf ("ALSA: hda - Fix system panic when DMA > 40 bits
for Nvidia audio controllers") simply disabled any DMA exceeding 32
bits for NVidia devices, even though they are capable of performing
DMA up to 40 bits. On some architectures (such as arm64), system memory
is not guaranteed to be 32-bit addressable by PCI devices, and so this
change prevents NVidia devices from working on platforms such as AMD
Seattle.
Since the original commit already mentioned that up to 40 bits of DMA
is supported, and given that the code has been updated in the meantime
to support a 40 bit DMA mask on other devices, revert commit 49d9e77e72cf
and explicitly set the DMA mask to 40 bits for NVidia devices.
Fixes: 49d9e77e72cf ('ALSA: hda - Fix system panic when DMA > 40 bits...')

The hi6220-sysctrl and hi6220-mediactrl are not only clock provider but
also reset controller. It worked fine that single sysctrl/mediactrl
device node in DT can be used to initialize clock driver and populate
platform device for reset controller. But it stops working after
commit 989eafd0b609 ("clk: core: Avoid double initialization of clocks")
gets merged. The commit sets flag OF_POPULATED during clock
initialization to skip the platform device populating for the same
device node. On hi6220, it effectively makes hi6220-sysctrl reset
driver not probe any more.
The patch changes hi6220 sysctrl and mediactrl clock init macro from
CLK_OF_DECLARE to CLK_OF_DECLARE_DRIVER, so that the reset driver using
the same hardware block can continue working.

For the gate part of the peripheral clock setting the bit disables the
clock and clearing it enables the clock. This is not the default behavior
of clk_gate component, so we need to use the CLK_GATE_SET_TO_DISABLE flag.

The commit 9b4cac33adc7 ("clk: max77686: Migrate to clk_hw based OF and
registration APIs") converted the driver to use the new provider API to
register clocks using clk_hw.
But unfortunately, in the conversion it missed to set the num_clks value
which lead to the following error when trying to register a clk provider:
[ 1.963782] of_clk_max77686_get: invalid index 0
[ 1.967460] ERROR: could not get clock /rtc@10070000:rtc_src(1)

While trying using a peripheral clock on a driver, I saw that the clock
pointer returned by the provider was NULL.
The problem was a missing indirection. It was the pointer stored in the

If the driver is built as a module, autoload won't work because the module

pkey_set() and pkey_get() were syscalls present in older versions
of the protection keys patches. The syscall number definitions
were inadvertently left in place. This patch removes them.
I did a git grep and verified that these are the last places in
the tree that these appear, save for the protection_keys.c tests
and Documentation. Those spots talk about functions called
pkey_get/set() which are wrappers for the direct PKRU
instructions, not the syscalls.

This fixes a very annoying regression on the Snowball SD card
that has been around for a while. It turns out that the device
tree does not configure the direction pins properly, nor sets
up the pins for the voltage converter properly at boot. Unless
all things are correctly set up, the feedback clock will not
work, and makes the driver spew messages in the console (but
it works, very slowly):
root@Ux500:/ mount /dev/mmcblk0p2 /mnt/
[ 9.953460] mmci-pl18x 80126000.sdi0_per1: error during DMA transfer!
[ 9.960296] mmcblk0: error -110 sending status command, retrying
[ 9.966461] mmcblk0: error -110 sending status command, retrying
[ 9.972534] mmcblk0: error -110 sending status command, aborting
Fix this by rectifying the device tree to correspond to that of
the Ux500 HREF boards plus the DAT31DIR setting that is unique for
the Snowball, and things start working smoothly. Add in the SDR12
and SDR25 modes which this host can do without any problems.
I don't know if this has ever been correct, sadly. It works after
this patch.

Commit 8a71f0c656e0 ("arm64: sysreg: replace open-coded mrs_s/msr_s with
{read,write}_sysreg_s") introduced a write_sysreg_s macro for writing
to system registers that are not supported by binutils.
Unfortunately, this was implemented with the wrong template (%0 vs %x0),
so in the case that we are writing a constant 0, we will generate
invalid instruction syntax and bail with a cryptic assembler error:
| Error: constant expression required
This patch fixes the template.

to require branches via PLT entries to reach the core kernel. The dynamic

In acpi_get_pmu_hw_inf we pass the address of a local variable to IS_ERR(),
which doesn't make sense, as the pointer must be a real, valid pointer.
This doesn't cause a functional problem, as IS_ERR() will evaluate as
false, but the check is bogus and causes static checkers to complain.

Commit 7ba5f605f3a0 ("arm64/numa: remove the limitation that cpu0 must
bind to node0") removed the numa cpu<->node mapping restriction whereby
logical cpu 0 always corresponds to numa node 0; removing the
restriction was correct, in that it does not really exist in practice
but the commit only updated the early mapping of logical cpu 0 to its
real numa node for the DT boot path, missing the ACPI one, leading to
boot failures on ACPI systems owing to missing node<->cpu map for
logical cpu 0.
Fix the issue by updating the ACPI boot path with code that carries out
the early cpu<->node mapping also for the boot cpu (ie cpu 0), mirroring
what is currently done in the DT boot path.

Makefile:49: *** the openjdk development package appears to me missing, install and try again. Stop.
The problem is that update-java-alternatives has multiple spaces between
fields, and cut treats each space as a new delimiter:
java-1.8.0-openjdk-ppc64el 1081 /usr/lib/jvm/java-1.8.0-openjdk-ppc64el
Fix this by using awk, which handles this fine.

This patch helps with Sukadev's vendor event tree where such events can happen.
>From Andi Kleen:
Any event including a .c/.o/.bpf currently triggers BPF compilation or loading
and then an error. This can happen for some Intel vendor events, which cannot
be used.
This patch fixes this problem by forbidding BPF file patch containing '{', '}'
and ',', make sure flex consumes the leading '{', instead of matching it using
a BPF file path.
Tested result:
$ perf stat -e '{unc_p_clockticks,unc_p_power_state_occupancy.cores_c0}' -a -I 1000
invalid or unsupported event: '{unc_p_clockticks,unc_p_power_state_occupancy.cores_c0}'
Run 'perf list' for a list of valid events
(as expected, interperted as event)
$ perf stat -e 'aaa.c' -a -I 1000
ERROR: problems with path aaa.c: No such file or directory
(as expected, interpreted as BPF source)
$ perf stat -e 'aaa.ccc' -a -I 1000
invalid or unsupported event: 'aaa.ccc'
(as expected, interpreted as event)
$ perf stat -e '{aaa.c}' -a -I 1000
ERROR: problems with path aaa.c: No such file or directory

Accesses to the rtsx usb device, which is the parent of the rtsx memstick
device, must not be done unless it's runtime resumed. This is currently not
the case and it could trigger various errors.
Fix this by properly deal with runtime PM in this regards. This means
making sure the device is runtime resumed, when serving requests via the
->request() callback or changing settings via the ->set_param() callbacks.

Accesses to the rtsx usb device, which is the parent of the rtsx memstick
device, must not be done unless it's runtime resumed.
Therefore when the rtsx_usb_ms driver polls for inserted memstick cards,
let's add pm_runtime_get|put*() to make sure accesses is done when the
rtsx usb device is runtime resumed.

Accesses of the rtsx sdmmc's parent device, which is the rtsx usb device,
must be done when it's runtime resumed. Currently this isn't case when
changing the led, so let's fix this by adding a pm_runtime_get_sync() and
a pm_runtime_put() around those operations.

The rtsx_usb_sdmmc driver may bail out in its ->set_ios() callback when no
SD card is inserted. This is wrong, as it could cause the device to remain
runtime resumed when it's unused. Fix this behaviour.

Potentially overflowing expression 1000000 * data->timeout_clks with
type unsigned int is evaluated using 32-bit arithmetic, and then used
in a context that expects an expression of type unsigned long long.
To avoid overflow, cast 1000000U to type unsigned long long.

Commit fefe6733e516 ("PCI: layerscape: Move struct pcie_port setup
to probe function") changed the init ordering of the pcie structure,
but started to use the pcie->drvdata field before initializing it.
Mayhem follows.
Fix this by moving the drvdata assignment right before the first use.
Tested on LS2085a.

With commit ef6000b4c670 ("Disable the __builtin_return_address()
warning globally after all)" the kernel does not warn at all again if
__builtin_return_address(n) is called with n > 0.
Besides the fact that this was a false warning on s390 anyway, due to
the always present backchain, we can now revert commit 5606330627ab
("s390/dumpstack: implement and use return_address()") again, to
simplify the code again.
After all I shouldn't have had return_address() implememted at all to
workaround this issue. So get rid of this again.

Before merging all different stack tracers the call traces printed had
an indicator if an entry can be considered reliable or not.
Unreliable entries were put in braces, reliable not. Currently all
lines contain these extra braces.
This patch restores the old behaviour by adding an extra "reliable"
parameter to the callback functions. Only show_trace makes currently
use of it.

As it turns out, the KASLR code breaks CONFIG_MODVERSIONS, since the
kcrctab has an absolute address field that is relocated at runtime
when the kernel offset is randomized.
This has been fixed already for PowerPC in the past, so simply wire up
the existing code dealing with this issue.

The GICv3 architecture specification mentions that a 64bit
register can be accessed using two 32bit accesses. What it
doesn't mention is that this is only guaranteed on a system
that implements AArch32, and a pure AArch64 system is allowed
not to support this. This causes issues with the GICR_TYPER
and GITS_TYPER registers, which are both RO 64bit registers.
In order to solve this, this patch switches the TYPER accesses
to the gic_read_typer macro already used in other parts of the
driver. This makes sure that we always use a 64bit access on
64bit systems, and two 32bit accesses on 32bit system.
