Subject: [PATCH 0/3] perf: arm-spe: Fix addresses of synthesized Arm SPE events

This patch set fixes problems related to address in synthesized events from SPE.

Committer testing:

perf record --no-bpf-event -e arm_spe_0/pa_enable=1/ -- sleep 1
perf inject -i perf.data -o perf-inj.data --itrace --strip
perf script -i perf-inj.data --fields hw:+addr,+phys_addr

Before:
	sleep 49337 [004] 20133.731889:          1             l1d-access:  ffffcbebcde1d5b8 [unknown] ([unknown])
	sleep 49337 [004] 20133.731889:          1             tlb-access:  ffffcbebcde1d5b8 [unknown] ([unknown])
	sleep 49337 [004] 20133.731889:          1                 memory:  ffffcbebcde1d5b8 [unknown] ([unknown])

After:
	sleep 49337 [004] 20133.731889:          1             l1d-access: ffff800034123970 ffffcbebcde1d5b8 [unknown] ([unknown])       153d19970
	sleep 49337 [004] 20133.731889:          1             tlb-access: ffff800034123970 ffffcbebcde1d5b8 [unknown] ([unknown])       153d19970
	sleep 49337 [004] 20133.731889:          1                 memory: ffff800034123970 ffffcbebcde1d5b8 [unknown] ([unknown])       153d19970
