In DCN hardware sequencer we do actually call ATOM_INIT correctly per
pipe. The workaround is not necessary for command table offloading.
[How]
Drop the workaround since it's not needed.

On PowerPC, the compiler will tag object files with whether they
use hard or soft float FP ABI and whether they use 64 or 128-bit
long double ABI. On systems with 64-bit long double ABI, a tag
will get emitted whenever a double is used, as on those systems
a long double is the same as a double. This will prevent linkage
as other files are being compiled with hard-float.
On ppc64, this code will never actually get used for the time
being, as the only currently existing hardware using it are the
Renoir APUs. Therefore, until this is testable and can be fixed
properly, at least make sure the build will not fail.

The IMA arch code attempts to inspect the "SetupMode" EFI variable
by populating a variable called efi_SetupMode_name with the string
"SecureBoot" and passing that to the EFI GetVariable service, which
obviously does not yield the expected result.
Given that the string is only referenced a single time, let's get
rid of the intermediate variable, and pass the correct string as
an immediate argument. While at it, do the same for "SecureBoot".

If one uses '-v' with 'perf trace', we can see the filter it puts in
place:
New filter for syscalls:sys_enter_prctl: (option==0xf) && (common_pid != 3859 && common_pid != 2757)
We still need to allow using plain '-e prctl' and have this turn into
creating a 'syscalls:sys_enter_prctl' event so that the filter can be
applied only to it as right now '-e prctl' ends up using the
'raw_syscalls:sys_enter/sys_exit'.
The end goal is to have something like:
# perf trace -e prctl/option==SET_NAME/
And have that use tracepoint filters or eBPF ones.

The Audioengine D1 (0x2912:0x30c8) does support reading the sample rate,

When setting sampling rate, the driver produces these warning messages:
[168840.944226] usb 3-2.2: current rate 4500480 is different from the runtime rate 44100
[168854.930414] usb 3-2.2: current rate 8436480 is different from the runtime rate 48000
[168905.185825] usb 3-2.1.2: current rate 30465 is different from the runtime rate 96000
As can be seen from the hexadecimal conversion, the current rate read
back is byte-reversed from the rate that was set.
44100 == 0x00ac44, 4500480 == 0x44ac00
48000 == 0x00bb80, 8436480 == 0x80bb00
96000 == 0x017700, 30465 == 0x007701
Rather than implementing a new quirk to reverse the order, just skip
