Lookup the coregroup id from the associativity array.
If unable to detect the coregroup id, fallback on the core id.
This way, ensure sched_domain degenerates and an extra sched domain is
not created.

Add support for grouping cores based on the device-tree classification.
- The last domain in the associativity domains always refers to the
core.
- If primary reference domain happens to be the penultimate domain in
the associativity domains device-tree property, then there are no
coregroups.
Currently "CACHE" domain happens to be the 2nd sched domain as per
powerpc_topology. This domain will collapse if cpumask of l2-cache is
same as SMT domain. However we could generalize this domain such that it
could mean either be a "CACHE" domain or a "BIGCORE" domain.
While setting up the

Current code assumes that cpumask of cpus sharing a l2-cache mask will

A new sched_domain_topology_level was added just for Power9. However the

While cpu_to_node is inline function with access to per_cpu variable.

The driver pretty much uses device managed functions. The only left-over is
the iio_device_register() function, which also requires an action-or-reset

"tx_adapter" shows" the type of wireless charging adapter;
"signal_strength" shows the coupling level

64bit and 32bit entry code have the same open coded syscall entry handling
after the bitwidth specific bits.
Move it to a helper function and share the code.

Replace the x86 variant with the generic version. Provide the relevant
architecture specific helper functions and defines.
Use a temporary define for idtentry_exit_user which will be cleaned up
seperately.

Like the syscall entry/exit code interrupt/exception entry after the real
low level ASM bits should not be different accross architectures.
Provide a generic version based on the x86 code.

Entering a guest is similar to exiting to user space. Pending work like
handling signals, rescheduling, task work etc. needs to be handled before
that.
Provide generic infrastructure to avoid duplication of the same handling
code all over the place.

This is strange. The problem description is missing quite a few important
details. For
Like syscall entry all architectures have similar and pointlessly different
code to handle pending work before returning from a syscall to user space.
1) One-time syscall exit work:
- rseq syscall exit
- audit
- syscall tracing
- tracehook (single stepping)
2)
Replace the syscall entry work handling with the generic version. Provide
the necessary helper inlines to handle the real architecture specific
parts, e.g. ptrace.
Use a temporary define for idtentry_enter_user which will be cleaned up
seperately.

Replace the x86 code with the generic variant. Use temporary defines for
idtentry_* which will be cleaned up in the next step.
