Merge tag 'v4.6-rc1' into for-linus-4.6
Linux 4.6-rc1 * tag 'v4.6-rc1': (12823 commits) Linux 4.6-rc1 f2fs/crypto: fix xts_tweak initialization NTB: Remove _addr functions from ntb_hw_amd orangefs: fix orangefs_superblock locking orangefs: fix do_readv_writev() handling of error halfway through orangefs: have ->kill_sb() evict the VFS side of things first orangefs: sanitize ->llseek() orangefs-bufmap.h: trim unused junk orangefs: saner calling conventions for getting a slot orangefs_copy_{to,from}_bufmap(): don't pass bufmap pointer orangefs: get rid of readdir_handle_s thp: fix typo in khugepaged_scan_pmd() MAINTAINERS: fill entries for KASAN mm/filemap: generic_file_read_iter(): check for zero reads unconditionally kasan: test fix: warn if the UAF could not be detected in kmalloc_uaf2 mm, kasan: stackdepot implementation. Enable stackdepot for SLAB arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections mm, kasan: add GFP flags to KASAN API mm, kasan: SLAB support kasan: modify kmalloc_large_oob_right(), add kmalloc_pagealloc_oob_right() ...
