i2c: core: Fix atomic xfer check for non-preempt config

commit a3368e1186e3ce8e38f78cbca019622095b1f331 upstream.

i2c: core: Fix atomic xfer check for non-preempt config

commit a3368e1186e3ce8e38f78cbca019622095b1f331 upstream.

Since commit aa49c90894d0 ("i2c: core: Run atomic i2c xfer when
!preemptible"), the whole reboot/power off sequence on non-preempt kernels
is using atomic i2c xfer, as !preemptible() always results to 1.

During device_shutdown(), the i2c might be used a lot and not all busses
have implemented an atomic xfer handler. This results in a lot of
avoidable noise, like:

[ 12.687169] No atomic I2C transfer handler for 'i2c-0'
[ 12.692313] WARNING: CPU: 6 PID: 275 at drivers/i2c/i2c-core.h:40 i2c_smbus_xfer+0x100/0x118
...

Fix this by allowing non-atomic xfer when the interrupts are enabled, as
it was before.

i2c: core: Run atomic i2c xfer when !preemptible

commit aa49c90894d06e18a1ee7c095edbd2f37c232d02 upstream.

Since bae1d3a05a8b, i2c transfers are non-atomic if preemption is
disabled. However, non-atomic i2c transfers require preemption (e.g. in
wait_for_completion() while waiting for the DMA).

panic() calls preempt_disable_notrace() before calling
emergency_restart(). Therefore, if an i2c device is used for the
restart, the xfer should be atomic. This avoids warnings like:

[ 12.667612] WARNING: CPU: 1 PID: 1 at kernel/rcu/tree_plugin.h:318 rcu_note_context_switch+0x33c/0x6b0
[ 12.676926] Voluntary context switch within RCU read-side critical section!

[ 13.001050] machine_restart from panic+0x2a8/0x32c

Use !preemptible() instead, which is basically the same check as
pre-v5.2.

and make the system reboot code use the S5 (system off) state by
default.

Specifics:

- Fix ACPI device object reference counting in (recently updated)
skl_int3472_fill_clk_pdata() (Andy Shevchenko).

- Fix a memory leak in APEI by avoiding to add a task_work to kernel
threads running when an asynchronous error is detected (Shuai Xue).

- Add ACPI support for handling system wakeups via GPIO wake capable
IRQs in addition to GPEs (Raul E Rangel).

- Make the system reboot code put ACPI-enabled systems into the S5
(system off) state which is necessary for some platforms to work as
expected (Kai-Heng Feng).

- Make the white space usage in the ACPI thermal driver more
consistent and drop redundant code from it (Rafael Wysocki)"

i2c: acpi: Use ACPI wake capability bit to set wake_irq

Device tree already has a mechanism to pass the wake_irq. It does this
by looking for the wakeup-source property and setting the
I2C_CLIENT_WAKE flag. This CL adds the ACPI equivalent. It uses the
ACPI interrupt wake flag to determine if the interrupt can be used to
wake the system. Previously the i2c drivers had to make assumptions and
blindly enable the wake IRQ. This can cause spurious wake events. e.g.,
If there is a device with an Active Low interrupt and the device gets
powered off while suspending, the interrupt line will go low since it's
no longer powered and wakes the system. For this reason we should
respect the board designers wishes and honor the wake bit defined on the
interrupt.
