Like some other Bay and Cherry Trail SoC based devices the Dell Venue
10 Pro 5055 has an embedded-controller which uses ACPI GPIO events to
report events instead of using the standard ACPI EC interface for this.
The EC interrupt is only used to report battery-level changes and
it keeps doing this while the system is suspended, causing the system
to not stay suspended.
Add an ignore-wake quirk for the GPIO pin used by the EC to fix the
spurious wakeups from suspend.

Neither the ACPI description on Intel Minnowboard (v1) platform provides
the required information to establish a generic handling nor the hardware
capable of doing it. According to the data sheet the hardware can generate
SCI events. Therefore, we need to hook from the driver into GPE handler of
the ACPI subsystem in order to catch and report GPIO-related events.

Realtek MIPS SoCs (platform name Otto) have GPIO controllers with up to
64 GPIOs, divided over two banks. Each bank has a set of registers for
32 GPIOs, with support for edge-triggered interrupts.
Each GPIO bank consists of four 8-bit GPIO ports (ABCD and EFGH). Most
registers pack one bit per GPIO, except for the IMR register, which
packs two bits per GPIO (AB-CD).
Although the byte order is currently assumed to have port A..D at offset
0x0..0x3, this has been observed to be reversed on other, Lexra-based,
SoCs (e.g. RTL8196E/97D/97F).
Interrupt support is disabled for the fallback devicetree-compatible
'realtek,otto-gpio'. This allows for quick support of GPIO banks in
which the byte order would be unknown. In this case, the port ordering
in the IMR registers may not match the reversed order in the other
registers (DCBA, and BA-DC or DC-BA).

In this round, we added a new mount option, "checkpoint_merge", which introduces
a kernel thread dealing with the f2fs checkpoints. Once we start to manage the
IO priority along with blk-cgroup, the checkpoint operation can be processed in
a lower priority under the process context. Since the checkpoint holds all the
filesystem operations, we give a higher priority to the checkpoint thread all
the time.
Enhancement:
- introduce gc_merge mount option to introduce a checkpoint thread
- improve to run discard thread efficiently
- allow modular compression algorithms
- expose # of overprivision segments to sysfs
- expose runtime compression stat to sysfs
Bug fix:
- fix OOB memory access by the node id lookup
- avoid touching checkpointed data in the checkpoint-disabled mode
- fix the resizing flow to avoid kernel panic and race conditions
- fix block allocation issues on pinned files
- address some swapfile issues

Merge tag 'f2fs-for-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, we added a new mount option, "checkpoint_merge", which
introduces a kernel thread dealing with the f2fs checkpoints. Once we
start to manage the IO priority along with blk-cgroup, the checkpoint
operation can be processed in a lower priority under the process
context. Since the checkpoint holds all the filesystem operations, we
give a higher priority to the checkpoint thread all the time.
Enhancements:
- introduce gc_merge mount option to introduce a checkpoint thread
- improve to run discard thread efficiently
- allow modular compression algorithms
- expose # of overprivision segments to sysfs
- expose runtime compression stat to sysfs
Bug fixes:
- fix OOB memory access by the node id lookup
- avoid touching checkpointed data in the checkpoint-disabled mode
- fix the resizing flow to avoid kernel panic and race conditions
- fix block allocation issues on pinned files
- address some swapfile issues
- fix hugtask problem and kernel panic during atomic write operations
- don't start checkpoint thread in RO
And, we've cleaned up some kernel coding style and build warnings. In
addition, we fixed some minor race conditions and error handling
routines"

There are two TCC activation temeprature.
One is the default TCC activation temperature, also known as TJ_MAX.
Another one is the effective TCC activation temperature, which is the
subtraction of default TCC activation temperature and TCC offset.
The name of variable tcc_activation_temp might be misleading here.
Thus rename tcc_activation_temp to tj_max, and use tcc_default and
tcc_offset to calculate the effective TCC activation temperature.
No functional change in this patch.

For Atom CPUs that have core cstate deeper than C6,
MSR_CORE_C6_RESIDENCY actually returns the residency for both CC6 and
deeper Core cstates.
Thus, the real Core C6 residency should be the subtraction of
MSR_CORE_C6_RESIDENCY return value and MSR_CORE_C6_RESIDENCY return value.

C-state pre-wake setting[1] is an optimization for some Intel CPUs to
be woken up from deep C-states in order to reduce latency. According to
the spec, the BIT30 is the C-state Pre-wake Disable. Expose this setting
accordingly.
Sample output from turbostat:
...
cpu51: MSR_IA32_POWER_CTL: 0x1a00a40059 (C1E auto-promotion: DISabled)
C-state Pre-wake: ENabled
cpu51: MSR_TURBO_RATIO_LIMIT: 0x2021212121212224

It was found that on Elkhart Lake the TSC frequency is driven by
a separate crystal-clock domain, which is different from the
BCLK domain which includes mperf. This has result in small different
speed thus inconsistence between TSC and the mperf, which caused the
Busy% to be higher than 100%. On this platform it seems that the mperf
runs faster than tsc when the CPU is 100% utilized:
delta tsc(18815473183) < delta mperf(18958403680) for 10 seconds.
To align TSC with mperf, leverage the tsc_tweak mechanism introduced for
cores newer than Skylake, so that TSC and mperf would be calculated in
the same domain.

Currently the turbostat treats ICX the same way as SKX and shares the
code among them. But one difference is that ICX does not support Package
C6 Retention, unlike SKX and CLX.
So this patch:
1. Splitting SKX and ICX in turbostat.
2. Removing Package C6 Rentention for ICX.
And after this split, it would be easier to cutomize Ice Lake Server
in turbostat in the future.

The idx_to_offset() function returns type int (32-bit signed), but
MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number.
The end result is that it hits the if (offset < 0) check in update_msr_sum()
which prevents the timer callback from updating the stat in the background when
long durations are used. The similar issue exists in offset_to_idx() and
update_msr_sum(). Fix this issue by converting the 'int' to 'off_t' accordingly.

It was reported that on Zen+ system turbostat started exiting,
which was tracked down to the MSR_PKG_ENERGY_STAT read failing because
offset_to_idx wasn't returning a non-negative index.
This patch combined the modification from Bingsong Si and
Bas Nieuwenhuizen and addd the MSR to the index system as alternative for
MSR_PKG_ENERGY_STATUS.

Apparently the TCC offset should not be used to adjust what temperature
