Subject: [PATCH v1 0/5] Remove NO_AUXTRACE build option
Switch the __get_cpuid feature for intel-pt to use the provided cpuid
function in perf, this removes the need for NO_AUXTRACE when the
feature detection fails. Remove the now unnecessary feature
detection. Remove NO_AUXTRACE as it just builds a more broken version
of perf and isn't guarding dependencies on any libraries, etc. Clean
up headers files for auxtrace.h.
This was prompted by needing to make a v2 patch set of:
https://lore.kernel.org/lkml/20251107170712.2302714-1-irogers@google.com/
due to a broken NO_AUXTRACE configuration.
Ian Rogers (5):
perf intel-pt: Use the perf provided "cpuid.h"
perf build: Don't add NO_AUXTRACE if missing feature-get_cpuid
tool build: Remove __get_cpuid feature test
perf build: Remove NO_AUXTRACE build option
perf auxtrace: Remove errno.h from auxtrace.h and fix transitive
dependencies
