Merge tag 'v5.8-rc4' into for-5.9/drivers
Merge in 5.8-rc4 for-5.9/block to setup for-5.9/drivers, to provide a clean base and making the life for the NVMe changes easier. Signed-off-by: Jens Axboe <axboe@kernel.dk> * tag 'v5.8-rc4': (732 commits) Linux 5.8-rc4 x86/ldt: use "pr_info_once()" instead of open-coding it badly MIPS: Do not use smp_processor_id() in preemptible code MIPS: Add missing EHB in mtc0 -> mfc0 sequence for DSPen .gitignore: Do not track `defconfig` from `make savedefconfig` io_uring: fix regression with always ignoring signals in io_cqring_wait() x86/ldt: Disable 16-bit segments on Xen PV x86/entry/32: Fix #MC and #DB wiring on x86_32 x86/entry/xen: Route #DB correctly on Xen PV x86/entry, selftests: Further improve user entry sanity checks x86/entry/compat: Clear RAX high bits on Xen PV SYSENTER i2c: mlxcpld: check correct size of maximum RECV_LEN packet i2c: add Kconfig help text for slave mode i2c: slave-eeprom: update documentation i2c: eg20t: Load module automatically if ID matches i2c: designware: platdrv: Set class based on DMI i2c: algo-pca: Add 0x78 as SCL stuck low status for PCA9665 mm/page_alloc: fix documentation error vmalloc: fix the owner argument for the new __vmalloc_node_range callers mm/cma.c: use exact_nid true to fix possible per-numa cma leak ...
