[PATCH v2 0/5] perf/amd/ibs: Assorted fixes

[Ravi Bangoria]

Address several issues in the AMD IBS perf code: interrupt accounting
for discarded samples, a Zen5-specific quirk, PhyAddrVal handling,
NMI-safety with perf_allow_kernel(), and a race between event add and
NMI.

Patches are prepared on tip/perf/core (7db06e329af3)

v1: https://lore.kernel.org/r/20260116033450.965-1-ravi.bangoria@xxxxxxx
v1->v2:
  - Split fixes series from future enhancements
  - Add interrupt throttling for zero-rip erratum #1197
  - Avoid calling perf_allow_kernel() in NMI context (new patch)
