Replace usages of perf_cpu_map with cpu_aggr map in places that are involved with 'perf stat' aggregation. This will then later be changed to be a map of cpu_aggr_id rather than an int so that more data can be stored. No functional changes. Signed-off-by:

Currently this is a duplicate of perf_cpu_map so that it can be used as a drop in replacement. In a later commit it will be changed from a map of ints to use the new cpu_aggr_id struct. No functional changes. Signed-off-by:

When a split lock is detected always make sure to disable interrupts before returning from the trap handler. The kernel exit code assumes that all exits run with interrupts disabled, otherwise the SWAPGS sequence can race against interrupts and cause recursing page faults and later panics. The problem will only happen on CPUs with split lock disable functionality, so Icelake Server, Tiger Lake, Snow Ridge, Jacobsville.

The reason cache merging is disabled with KASAN is because KASAN puts its metadata right after the allocated object. When the merged caches have slightly different sizes, the metadata ends up in different places, which KASAN doesn't support. It might be possible to adjust the metadata allocation algorithm and make it friendly to the cache merging code. Instead this change takes a simpler approach and allows merging caches when no metadata is present. Which is the case for hardware tag-based KASAN with kasan.mode=prod.

KASAN marks caches that are sanitized with the SLAB_KASAN cache flag. Currently if the metadata that is appended after the object (stores e.g. stack trace ids) doesn't fit into KMALLOC_MAX_SIZE (can only happen with SLAB, see the comment in the patch), KASAN turns off sanitization completely. With this change sanitization of the object data is always enabled. However the metadata is only stored when it fits. Instead of checking for SLAB_KASAN flag accross the code to find out whether the metadata is there, use cache->kasan_info.alloc/free_meta_offset. As 0 can be a valid value for free_meta_offset, introduce KASAN_NO_FREE_META as an indicator that the free metadata is missing. Without this change all sanitized KASAN objects would be put into quarantine with generic KASAN. With this change, only the objects that have metadata (i.e. when it fits) are put into quarantine, the rest is freed right away. Along the way rework __kasan_cache_create() and add claryfying comments.
