+Subject: ACPICA: Tables: Fix an issue that FACS initialization is performed twice
+
+From: Lv Zheng <lv.zheng@intel.com>
+
+commit c04be18448355441a0c424362df65b6422e27bda upstream.
+
+ACPICA commit 90f5332a15e9d9ba83831ca700b2b9f708274658
+
+This patch adds a new FACS initialization flag for acpi_tb_initialize().
+acpi_enable_subsystem() might be invoked several times in OS bootup process,
+and we don't want FACS initialization to be invoked twice. Lv Zheng.

+Subject: Btrfs: use kmem_cache_free when freeing entry in inode cache
+
+From: Filipe Manana <fdmanana@suse.com>
+
+commit c3f4a1685bb87e59c886ee68f7967eae07d4dffa upstream.
+
+The free space entries are allocated using kmem_cache_zalloc(),
+through __btrfs_add_free_space(), therefore we should use
+kmem_cache_free() and not kfree() to avoid any confusion and
+any potential problem. Looking at the kfree() definition at
+mm/slab.c it has the following comment:
+
+ /*
+ * (...)
+ *
+ * Don't free memory not originally allocated by kmalloc()
+ * or you will run into trouble.
+ */
+
+So better be safe and use kmem_cache_free().

+Subject: crush: fix a bug in tree bucket decode
+
+From: Ilya Dryomov <idryomov@gmail.com>
+
+commit 82cd003a77173c91b9acad8033fb7931dac8d751 upstream.
+
+struct crush_bucket_tree::num_nodes is u8, so ceph_decode_8_safe()
+should be used. -Wconversion catches this, but I guess it went
+unnoticed in all the noise it spews. The actual problem (at least for
+common crushmaps) isn't the u32 -> u8 truncation though - it's the
+advancement by 4 bytes instead of 1 in the crushmap buffer.

+fc->release is called from fuse_conn_put() which was used in the error
