2020-12-23drm/amd/display: Fix memory leaks in S3 resumeStylon Wang1-1/+2
EDID parsing in S3 resume pushes new display modes to probed_modes list but doesn't consolidate to actual mode list. This creates a race condition when amdgpu_dm_connector_ddc_get_modes() re-initializes the list head without walking the list and results in memory leak.

2020-12-22Merge branch 'akpm' (patches from Andrew)Linus Torvalds72-1460/+2775
Merge KASAN updates from Andrew Morton. This adds a new hardware tag-based mode to KASAN. The new mode is similar to the existing software tag-based KASAN, but relies on arm64 Memory Tagging Extension (MTE) to perform memory and pointer tagging (instead of shadow memory and compiler instrumentation). By Andrey Konovalov and Vincenzo Frascino. * emailed patches from Andrew Morton <[email protected]>: (60 commits) kasan: update documentation kasan, mm: allow cache merging with no metadata kasan: sanitize objects when metadata doesn't fit kasan: clarify comment in __kasan_kfree_large kasan: simplify assign_tag and set_tag calls kasan: don't round_up too much kasan, mm: rename kasan_poison_kfree kasan, mm: check kasan_enabled in annotations kasan: add and integrate kasan boot parameters kasan: inline (un)poison_range and check_invalid_free kasan: open-code kasan_unpoison_slab kasan: inline random_tag for HW_TAGS kasan: inline kasan_reset_tag for tag-based modes kasan: remove __kasan_unpoison_stack kasan: allow VMAP_STACK for HW_TAGS mode kasan, arm64: unpoison stack only with CONFIG_KASAN_STACK kasan: introduce set_alloc_info kasan: rename get_alloc/free_info kasan: simplify quarantine_put call site kselftest/arm64: check GCR_EL1 after context switch ...
