Allow user to map the OA buffer and also trigger reports into it. CI fixes: v1: Fixes a memory corruption due to addition of OA whitelist on demand. v2: Spinlock when applying whitelist v3: Use uncore->lock. Do not check for wal->count when applying whitelist. v4: Refresh and rerun with newly added test (forked access). v5: - Split patches into smaller units - Grow the wal->list only for the engine that needs it. - Bring back the wal->count check when applying whitelist during resume v6: Fix checkpatch and sparse warnings v7: - Fix mem leak - Grow wal->list only if wal->count is not aligned to WAL_LIST_CHUNK
