"New features:
- swapfile support - after a long time it's here, with some
limitations where COW design does not work well with the swap
implementation (nodatacow file, no compression, cannot be
snapshotted, not possible on multiple devices, ...), as this is the
most restricted but working setup, we'll try to improve that in the
future
- metadata uuid - an optional incompat feature to assign a new
filesystem UUID without overwriting all metadata blocks, stored
only in superblock
- more balance messages are printed to system log, initial is in the
format of the command line that would be used to start it
Fixes:
- tag pages of a snapshot to better separate pages that are involved
in the snapshot (and need to get synced) from newly dirtied pages
that could slow down or even livelock the snapshot operation
- improved check of filesystem id associated with a device during
scan to detect duplicate devices that could be mixed up during
mount
- fix device replace state transitions, eg. when it ends up
interrupted and reboot tries to restart balance too, or when
start/cancel ioctls race
- fix a crash due to a race when quotas are enabled during snapshot
creation
- GFP_NOFS/memalloc_nofs_* fixes due to GFP_KERNEL allocations in
transaction context
- fix fsync of files with multiple hard links in new directories
- fix race of send with transaction commits that create snapshots
Core changes:
- cleanups:
* further removals of now-dead fsync code
* core function for finding free extent has been split and
provides a base for further cleanups to make the logic more
understandable
* removed lot of indirect callbacks for data and metadata inodes
* simplified refcounting and locking for cloned extent buffers
* removed redundant function arguments
* defines converted to enums where appropriate
- separate reserve for delayed refs from global reserve, update logic
to do less trickery and ad-hoc heuristics, move out some related
expensive operations from transaction commit or file truncate
- dev-replace switched from custom locking scheme to semaphore
- remove first phase of balance that tried to make some space for the
relocation by calling shrink and grow, this did not work as
expected and only introduced more error states due to potential
resize failures, slightly improves the runtime as the chunks on all
devices are not needlessly enumerated
- clone and deduplication now use generic helper that adds a few more
checks that were missing from the original btrfs implementation of
the ioctls"

"Here's the main MIPS pull for Linux 4.21. Core architecture changes
include:
- Syscall tables & definitions for unistd.h are now generated by
scripts, providing greater consistency with other architectures &
making it easier to add new syscalls.
- Support for building kernels with no floating point support, upon
which any userland attempting to use floating point instructions
will receive a SIGILL. Mostly useful to shrink the kernel & as
preparation for nanoMIPS support which does not yet include FP.
- MIPS SIMD Architecture (MSA) vector register context is now exposed
by ptrace via a new NT_MIPS_MSA regset.
- ASIDs are now stored as 64b values even for MIPS32 kernels,
expanding the ASID version field sufficiently that we don't need to
worry about overflow & avoiding rare issues with reused ASIDs that
have been observed in the wild.
- The branch delay slot "emulation" page is now mapped without write
permission for the user, preventing its use as a nice location for
attacks to execute malicious code from.
- Support for ioremap_prot(), primarily to allow gdb or other ptrace
users the ability to view their tracee's memory using the same
cache coherency attribute.
- Optimizations to more cpu_has_* macros, allowing more to be
compile-time constant where possible.
- Enable building the whole kernel with UBSAN instrumentation.
- Enable building the kernel with link-time dead code & data
elimination.
Platform specific changes include:
- The Boston board gains a workaround for DMA prefetching issues with
the EG20T Platform Controller Hub that it uses.
- Cleanups to Cavium Octeon code removing about 20k lines of
redundant code, mostly unused or duplicate register definitions in
headers.
- defconfig updates for the DECstation machines, including new
defconfigs for r4k & 64b machines.
- Further work on Loongson 3 support.

"This round is dominated by NXP's i.MX clk drivers. We gained support
for two or three i.MX SoCs in here and that mostly means a lot of

Beyond that platform, there are some new Mediatek, Amlogic, and
Qualcomm clk drivers added in here, and then we get to the long tail
of driver updates and non-critical fixes all around, including code
for vendors such as Renesas, Rockchip, Nvidia, and Allwinner. Overall,
the driver updates look normal.
Apart from the usual driver updates we have an update to make
registering OF based clk providers a little simpler when they're
devices created as a child of a device backed by a node in DT. Drivers
don't have to jump through hoops to unregister the provider upon
driver removal anymore because the API does the right thing and uses
the parent device DT node.

net: dccp: fix kernel crash on module load
Patch eedbbb0d98b2 "net: dccp: initialize (addr,port) ..."
added calling to inet_hashinfo2_init() from dccp_init().
However, inet_hashinfo2_init() is marked as __init(), and
thus the kernel panics when dccp is loaded as module. Removing
__init() tag from inet_hashinfo2_init() is not feasible because
it calls into __init functions in mm.
This patch adds inet_hashinfo2_init_mod() function that can
be called after the init phase is done; changes dccp_init() to
call the new function; un-marks inet_hashinfo2_init() as
exported.

drivers/net: appletalk/cops: remove redundant if statement and mask
The two different assignments for pkt_len are actually the same and
so the if statement is redundant and can be removed. Masking a u8
return value from inb() with 0xFF is also redundant and can also be
emoved.
Similarly, the two different outb calls are identical as the mask
of 0xff on the second outb is redundant since a u8 is being written,
so the if statement is also redundant and can be also removed.
Detected by CoverityScan, CID#1475639 ("Identical code for different
branches")
V2: Remove the if statement for the outb calls, thanks to David
Miller for spotting this.

After some investigation I figured out that recently added cleanup code
tries to call VLAN filtering de-initialization function which exist only
for newer hardware. Corresponding function pointer is not
set (== 0) for older hardware, namely these chips:
Broadcom Inc. and subsidiaries NetXtreme II BCM57711E 10-Gigabit PCIe [14e4:1650]
Function bnx2x_init_vlan_mac_fp_objs() from
drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.h decides whether to
initialize relevant pointers in bnx2x_sp_objs.vlan_obj or not.
This regression was introduced after v4.20-rc7, and still exists in v4.20
release.

- The "givcipher" (GIVCIPHER) algorithm type. No algorithms are
registered with this type anymore, so it's unneeded.
- The "const char *geniv" member of aead_alg, ablkcipher_alg, and
