CS35L41 has a DSP which is able to run firmware, as well as a tuning file.
Different systems may want to use different firmwares and tuning files, and
some firmwares/tunings may not be compatible with other systems.
To allow a system to select the correct fimware/tuning, we can read an _SUB
from the ACPI. This _SUB can then be used to uniquely identify the system
in the firmware/tuning file name.
Add a helper function which reads the _SUB, so this can be used by other
parts in the future.
Add support inside the CS35L41 ASoC driver to read this _SUB, and save it
appropriately.
With the new design in place, the show() and store() callbacks check if
the policy is active or not before proceeding any further to avoid
potential races. And in order to guarantee that cpufreq_policy_free()
must be called after clearing the policy->cpus mask, i.e. by marking the
policy inactive.
In order to avoid introducing a bug around this later, print a warning
message if we end up freeing an active policy.
Also update cpufreq_online() a bit to make sure we clear the cpus mask
for each error case before calling cpufreq_policy_free().

The SCMI v3.1 adds support for power values in micro-Watts. They are not
always in milli-Watts anymore (ignoring the bogo-Watts). Thus, the power
must be converted conditionally before sending to Energy Model. Add the
logic which handles the needed checks and conversions.

In SCMI v3.1 the power scale can be in micro-Watts. The upper layers, e.g.
cpufreq and EM should handle received power values properly (upscale when
needed). Thus, provide an interface which allows to check what is the
scale for power values. The old interface allowed to distinguish between
bogo-Watts and milli-Watts only (which was good for older SCMI spec).

The milli-Watts precision causes rounding errors while calculating
efficiency cost for each OPP. This is especially visible in the 'simple'
Energy Model (EM), where the power for each OPP is provided from OPP
framework. This can cause some OPPs to be marked inefficient, while
using micro-Watts precision that might not happen.
Update all EM users which access 'power' field and assume the value is
in milli-Watts.
Solve also an issue with potential overflow in calculation of energy
estimation on 32bit machine. It's needed now since the power value
(thus the 'cost' as well) are higher.
Example calculation which shows the rounding error and impact:
power = 'dyn-power-coeff' * volt_mV * volt_mV * freq_MHz
power_a_uW = (100 * 600mW * 600mW * 500MHz) / 10^6 = 18000
power_a_mW = (100 * 600mW * 600mW * 500MHz) / 10^9 = 18
power_b_uW = (100 * 605mW * 605mW * 600MHz) / 10^6 = 21961
power_b_mW = (100 * 605mW * 605mW * 600MHz) / 10^9 = 21
max_freq = 2000MHz
cost_a_mW = 18 * 2000MHz/500MHz = 72
cost_a_uW = 18000 * 2000MHz/500MHz = 72000
cost_b_mW = 21 * 2000MHz/600MHz = 70 // <- artificially better
cost_b_uW = 21961 * 2000MHz/600MHz = 73203
The 'cost_b_mW' (which is based on old milli-Watts) is misleadingly
better that the 'cost_b_uW' (this patch uses micro-Watts) and such
would have impact on the 'inefficient OPPs' information in the Cpufreq
framework. This patch set removes the rounding issue.

Currently, when loading a kernel image via the kexec_file_load() system
call, arm64 can only use the .builtin_trusted_keys keyring to verify
a signature whereas x86 can use three more keyrings i.e.
.secondary_trusted_keys, .machine and .platform keyrings. For example,
one resulting problem is kexec'ing a kernel image would be rejected
with the error "Lockdown: kexec: kexec of unsigned images is restricted;
see man kernel_lockdown.7".
This patch set enables arm64 to make use of the same keyrings as x86 to
verify the signature kexec'ed kernel image.

As requested
(http://lkml.kernel.org/r/87ee0q7b92.fsf@email.froward.int.ebiederm.org),
this series converts weak functions in kexec to use the #ifdef approach.
Quoting the 3e35142ef9 ("kexec_file: drop weak attribute from
arch_kexec_apply_relocations[_add]") changelog:
: Since commit d1bcae833b32f1 ("ELF: Don't generate unused section symbols")
: [1], binutils (v2.36+) started dropping section symbols that it thought
: were unused. This isn't an issue in general, but with kexec_file.c, gcc
: is placing kexec_arch_apply_relocations[_add] into a separate
: .text.unlikely section and the section symbol ".text.unlikely" is being
: dropped. Due to this, recordmcount is unable to find a non-weak symbol in
: .text.unlikely to generate a relocation record against.
This patch (of 2);
Drop __weak attribute from functions in kexec_file.c:
- arch_kexec_kernel_image_probe()
- arch_kimage_file_post_load_cleanup()
- arch_kexec_kernel_image_load()
- arch_kexec_locate_mem_hole()
- arch_kexec_kernel_verify_sig()
arch_kexec_kernel_image_load() calls into kexec_image_load_default(), so
drop the static attribute for the latter.
arch_kexec_kernel_verify_sig() is not overridden by any architecture, so
drop the __weak attribute.

When PCH-attached DMICs are used on a SoundWire-based platform, all
known devices pin-mux SoundWire link2 and link3 with DMIC, and only
use link0 and link1 for SoundWire.
The HP Omen16 is the first exception to the rule, with SoundWire using
link0 and link3. Rather than using a fixed mask, let's count the
number of SoundWire links used.

06781a5026 Fixes the calculation of the DEVICE_BUSY_TIMEOUT register
value from busy_timeout_cycles. busy_timeout_cycles is calculated wrong
though: It is calculated based on the maximum page read time, but the
timeout is also used for page write and block erase operations which
require orders of magnitude bigger timeouts.
Fix this by calculating busy_timeout_cycles from the maximum of
tBERS_max and tPROG_max.
This is for now the easiest and most obvious way to fix the driver.
There's room for improvements though: The NAND_OP_WAITRDY_INSTR tells us
the desired timeout for the current operation, so we could program the
timeout dynamically for each operation instead of setting a fixed
timeout. Also we could wire up the interrupt handler to actually detect
and forward timeouts occurred when waiting for the chip being ready.
As a sidenote I verified that the change in 06781a5026 is really
correct. I wired up the interrupt handler in my tree and measured the
time between starting the operation and the timeout interrupt handler
coming in. The time increases 41us with each step in the timeout
register which corresponds to 4096 clock cycles with the 99MHz clock
that I have.

Using bin_attributes with a 0 size causes fstat and friends to return that
0 size. This breaks userspace code that retrieves the size before reading
the file. Rather than reverting 75bd50fa84 ("drivers/base/node.c: use
bin_attribute to break the size limitation of cpumap ABI") let's put in a
size value at compile time.
For cpulist the maximum size is on the order of
NR_CPUS * (ceil(log10(NR_CPUS)) + 1)/2
which for 8192 is 20480 (8192 * 5)/2. In order to get near that you'd need
a system with every other CPU on one node. For example: (0,2,4,8, ... ).
To simplify the math and support larger NR_CPUS in the future we are using
(NR_CPUS * 7)/2. We also set it to a min of PAGE_SIZE to retain the older
behavior for smaller NR_CPUS.
The cpumap file the size works out to be NR_CPUS/4 + NR_CPUS/32 - 1
(or NR_CPUS * 9/32 - 1) including the ","s.
Add a set of macros for these values to cpumask.h so they can be used in
multiple places. Apply these to the handful of such files in
drivers/base/topology.c as well as node.c.
As an example, on an 80 cpu 4-node system (NR_CPUS == 8192):
before:
-r--r--r--. 1 root root 0 Jul 12 14:08 system/node/node0/cpulist
-r--r--r--. 1 root root 0 Jul 11 17:25 system/node/node0/cpumap
after:
-r--r--r--. 1 root root 28672 Jul 13 11:32 system/node/node0/cpulist
-r--r--r--. 1 root root 4096 Jul 13 11:31 system/node/node0/cpumap
CONFIG_NR_CPUS = 16384
-r--r--r--. 1 root root 57344 Jul 13 14:03 system/node/node0/cpulist
-r--r--r--. 1 root root 4607 Jul 13 14:02 system/node/node0/cpumap
The actual number of cpus doesn't matter for the reported size since they
are based on NR_CPUS.
