[ Upstream commit 20ed9fa4965875fdde5bfd65d838465e38d46b22 ]
Commit 93315e46b000fc80 ("perf/core: Add speculation info to branch entries") added a new field in between type and new_type. Perf has its own copy of this struct so update it to match the kernel side.
This doesn't currently cause any issues because new_type is only used by the Arm BRBE driver which isn't merged yet.
Committer notes:
Is this really an ABI? How are we supposed to deal with old perf.data files with new tools and vice versa? :-\
