This patch converts riscv to use the generic entry infrastructure from
kernel/entry/*. The generic entry makes maintainers' work easier and
codes more elegant. Here are the changes:
- More clear entry.S with handle_exception and ret_from_exception
- Get rid of complex custom signal implementation
- Move syscall procedure from assembly to C, which is much more
readable.
- Connect ret_from_fork & ret_from_kernel_thread to generic entry.
- Wrap with irqentry_enter/exit and syscall_enter/exit_from_user_mode
- Use the standard preemption code instead of custom

commit 1796f808e4 ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
changed the policy such that I2C touchpads may be able to wake up the
system by default if the system is configured as such.
However on Clevo NL5xNU there is a mistake in the ACPI tables that the
TP_ATTN# signal connected to GPIO 9 is configured as ActiveLow and level
triggered but connected to a pull up. As soon as the system suspends the
touchpad loses power and then the system wakes up.
To avoid this problem, introduce a quirk for this model that will prevent
the wakeup capability for being set for GPIO 9.
This patch is analoge to a very similar patch for NL5xRU, just the DMI
string changed.

It's logical to check ACPI device for NULL inside
acpi_get_driver_gpio_data() instead of requiring that
in each caller.
Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
While trying to set up an SSDT override for a USB-2-I2C chip [0],
I realized that the function acpi_gpiochip_find() was using the parent
of the gpio_chip to do the ACPI matching.
This works fine on my Ice Lake laptop because AFAICT, the DSDT presents
the PCI device INT3455 as the "Device (GPI0)", but is in fact handled
by the pinctrl driver in Linux.
The pinctrl driver then creates a gpio_chip device. This means that the
gc->parent device in that case is the GPI0 device from ACPI and everything
works.
However, in the hid-cp2112 case, the parent is the USB device, and the
gpio_chip is directly under that USB device. Which means that in this case
gc->parent points at the USB device, and so we can not do an ACPI match
towards the GPIO device.
I think it is safe to resolve the ACPI matching through the fwnode
because when we call gpiochip_add_data(), the first thing it does is
setting a proper gc->fwnode: if it is not there, it borrows the fwnode
of the parent.
So in my Ice Lake case, gc->fwnode is the one from the parent, meaning
that the ACPI handle we will get is the one from the GPI0 in the DSDT
(the pincrtl one). And in the hid-cp2112 case, we get the actual
fwnode from the gpiochip we created in the HID device, making it working.

In data=journal mode, page should be dirtied only when it has buffers
for checkpoint or it is writeably mapped. In the first case, we don't
need to do anything special. In the second case, page was already added
to the journal by ext4_page_mkwrite() and since transaction commit
writeprotects mapped pages again, page should be writeable (and thus
dirtied) only while it is part of the running transaction. So nothing
needs to be done either. The only special case is when someone pins the
page and uses this pin for modifying page data. So recognize this
special case and only then mark the page as having data that needs
adding to the journal.

TLB bugs. Furthermore, while igt_cs_tlb is hitting some
unforeseen issues, these issues are either false positives
due to the test being poorly formatted, or are true
positives that can be more easily diagnosed with smaller
tests. As such, igt_cs_tlb is superceded by and obsoleted
by gt_tlb, meaning it can be removed.

Restore synchronous probing for Arizona regulators as the main MFD
relies on the ordering of the devices probing.
As these regulators are built into the CODEC and typically have no DT
representation the regulator framework is unaware of their existence
until the driver probes. These means the probing of the driver needs to
be synchronous to ensure the regulators are not substitued for the dummy
later when the users request them.

The qcom,sdx55-apcs-gcc is followed by another compatible (syscon), thus
the 'if' clause must match by contains.

This is just to ensure that .usage_power is properly initialized and
doesn't contain random stack data. The other members of struct pwm_state
should get a value assigned in a successful call to .get_state(). So in
the absence of bugs in driver implementations, this is only a safe-guard
and no fix.
