Delete redundant core_data.core_id.

No functional change.
Signed-off-by: Len Brown <len.brown@intel.com>
The Linux Kernel topology sysfs is flawed.
core_id is not globally unique, but is per-package.
Turbostat works around this when it needs to, with
rapl_core_id = cpus[cpu].core_id;
rapl_core_id += cpus[cpu].package_id * nr_cores_per_package
Otherwise, turbostat handles core_id as subservient to each package.
As there is only one core_id namespace, rename
physical_core_id to simply be core_id.
No functional change.
Signed-off-by: Len Brown <len.brown@intel.com>
The kernel topology sysfs uses the name "physical_package_id"
because it is allowed to be sparse.
Inside Turbostat, that physical package_id namespace is the only
package_id namespace, so re-name it to simply be "package_id"
in cpus[].

version 2026.02.04
Add support for L2 cache statistics: L2MRPS and L2%hit
L2 statistics join the LLC in the "cache" counter group.
While the underlying LLC perf kernel support was architectural,
L2 perf counters are model-specific:
Support Intel Xeon -- Sapphire Rapids and newer.
Support Intel Atom -- Gracemont and newer.
Support Intel Hybrid -- Alder Lake and newer.
Example:
alder-lake-n$ sudo turbostat --quiet --show CPU,Busy%,cache my_workload
CPU Busy% LLCMRPS LLC%hit L2MRPS L2%hit
- 49.82 1210 85.02 2909 31.63
0 99.14 322 88.89 767 32.38
1 0.91 1 32.47 1 18.86
2 0.20 0 40.78 0 23.34
3 99.17 295 81.79 706 31.89
4 0.68 1 58.71 1 15.61
5 99.16 299 85.65 726 31.32
6 0.08 0 45.35 0 31.71
7 99.21 293 83.63 707 30.92
where "my_workload" is a wrapper for a yogini workload
that has 4 fully-busy threads with 2MB working set each.
Note that analogous to the system summary for multiple LLC systems,
the system summary row for the L2 is the aggregate of all CPUS in the
system -- there is no per-cache roll-up.

In unittest_data_add(), if of_resolve_phandles() fails, the allocated
unittest_data is not freed, leading to a memory leak.
Fix this by using scope-based cleanup helper __free(kfree) for automatic
resource cleanup. This ensures unittest_data is automatically freed when
it goes out of scope in error paths.
For the success path, use retain_and_null_ptr() to transfer ownership
of the memory to the device tree and prevent double freeing.

When building kselftests with a toolchain that enables source
fortification (e.g., Android's build environment, which uses
-D_FORTIFY_SOURCE=3), a build failure occurs in tests that use an
empty FIXTURE().
The root cause is that an empty fixture struct results in
`sizeof(self_private)` evaluating to 0. The compiler's fortification
checks then detect the `memset()` call with a compile-time constant size
of 0, issuing a `-Wuser-defined-warnings` which is promoted to an error
by `-Werror`.
An initial attempt to guard the call with `if (sizeof(self_private) > 0)`
was insufficient. The compiler's static analysis is aggressive enough
to flag the `memset(..., 0)` pattern before evaluating the conditional,
thus still triggering the error.
To resolve this robustly, this change introduces a `static inline`
helper function, `__kselftest_memset_safe()`. This function wraps the
size check and the `memset()` call. By replacing the direct `memset()`
in the `__TEST_F_IMPL` macro with a call to this helper, we create an
abstraction boundary. This prevents the compiler's static analyzer from
"seeing" the problematic pattern at the macro expansion site, resolving
the build failure.
Build Context:
Compiler: Android (14488419, +pgo, +bolt, +lto, +mlgo, based on r584948) clang version 22.0.0 (https://android.googlesource.com/toolchain/llvm-project 2d65e4108033380e6fe8e08b1f1826cd2bfb0c99)
