Panfrost depends on the simple_ondemand governor, and therefore

Right now, the BO is mapped as a cached region when ->vmap() is called
and the underlying object is not a dmabuf.
Doing that makes cache management a bit more complicated (you'd need
to call dma_map/unmap_sg() on the ->sgt field everytime the BO is about
to be passed to the GPU/CPU), so let's map the BO with writecombine
attributes instead (as done in most drivers).

When calling kmalloc with GFP_KERNEL in case CONFIG_SLOB is unset,
kmem_cache_alloc_trace is called.
In case CONFIG_TRACING is set, kmem_cache_alloc_trace will ball
slab_alloc, which will call slab_pre_alloc_hook which might_sleep_if.
The context in which it is called in this case, the
intel_sst_interrupt_mrfld, calling a sleeping kmalloc generates a BUG():

Packets received at the NFP driver may be redirected to egress of another
netdev (e.g. in the case of OvS internal ports). On the egress path, some
processes, like TC egress hooks, may expect the network header offset
field in the skb to be correctly set. If this is not the case there is
potential for abnormal behaviour and even the triggering of BUG() calls.
Set the skb network header field before the mac header pull when doing a
packet redirect.

Commit 794200d66273 ("tcp: undo cwnd on Fast Open spurious SYNACK
retransmit") may cause tcp_fastretrans_alert() to warn about pending
retransmission in Open state. This is triggered when the Fast Open
server both sends data and has spurious SYNACK retransmission during
the handshake, and the data packets were lost or reordered.
The root cause is a bit complicated:
(1) Upon receiving SYN-data: a full socket is created with
snd_una = ISN + 1 by tcp_create_openreq_child()
(2) On SYNACK timeout the server/sender enters CA_Loss state.
(3) Upon receiving the final ACK to complete the handshake, sender
does not mark FLAG_SND_UNA_ADVANCED since (1)
Sender then calls tcp_process_loss since state is CA_loss by (2)
(4) tcp_process_loss() does not invoke undo operations but instead
mark REXMIT_LOST to force retransmission
(5) tcp_rcv_synrecv_state_fastopen() calls tcp_try_undo_loss(). It
changes state to CA_Open but has positive tp->retrans_out
(6) Next ACK triggers the WARN_ON in tcp_fastretrans_alert()
The step that goes wrong is (4) where the undo operation should
have been invoked because the ACK successfully acknowledged the
SYN sequence. This fixes that by specifically checking undo
when the SYN-ACK sequence is acknowledged. Then after
tcp_process_loss() the state would be further adjusted based
in tcp_fastretrans_alert() to avoid triggering the warning in (6).

ibmvnic: Fixes for device reset handling
This series contains three unrelated fixes to issues seen during
device resets. The first patch fixes an error when the driver requests
to deactivate the link of an uninitialized device, resulting in a
failure to reset. Next, a patch to fix multicast transmission
failures seen after a driver reset. The final patch fixes mishandling
of memory allocation failures during device initialization, which
caused a kernel oops.

If you configure a route with multiple labels, e.g.

A warning is logged:
kernel: [ 130.561819] netlink: 'ip': attribute type 1 has an invalid

This happens because mpls_iptunnel_policy has set the type of

[Resent to net instead of net-next - may clash with Anders Roxell's patch
series addressing duplicate module names]
Commit 31dd83b96641 ("net-next: phy: new Asix Electronics PHY driver")
introduced a new PHY driver drivers/net/phy/asix.c that causes a module
name conflict with a pre-existiting driver (drivers/net/usb/asix.c).
The PHY driver is used by the X-Surf 100 ethernet card driver, and loaded
by that driver via its PHY ID. A rename of the driver looks unproblematic.

leaves ABS_X min = max = 0 which may prompt an X server to ignore

DMI strings (bad) and use a portrait screen rotated 90 degrees (ugly).
Because of the too generic DMI strings this entry is also doing bios-date

In commit
39388e80f9b0c ("x86/fpu: Don't save fxregs for ia32 frames in copy_fpstate_to_sigframe()")
I removed the statement
| if (ia32_fxstate)
| copy_fxregs_to_kernel(fpu);
and argued that it was wrongly merged because the content was already
saved in kernel's state.
This was wrong: It is required to write it back because it is only
saved on the user-stack and save_fsave_header() reads it from task's
FPU-state. I missed that part…
Save x87 FPU state unless thread's FPU registers are already up to date.

This driver does not support reading more than 255 bytes at once because
the register for storing the number of bytes to read is only 8 bits. Add
a max_read_len quirk to enforce this.
This was found when using this driver with the SFP driver, which was
previously reading all 256 bytes in the SFP EEPROM in one transaction.
This caused a bunch of hard-to-debug errors in the xiic driver since the
driver/logic was treating the number of bytes to read as zero.
Rejecting transactions that aren't supported at least allows the problem
to be diagnosed more easily.

24 bit expanders use REG_ADDR_AI in combination with register addressing. This
conflicts with regmap which takes this bit as part of the register number,
i.e. a second cache entry is defined for accessed with REG_ADDR_AI being
set although on the chip it is the same register as with REG_ADDR_AI being
cleared.
The problem was introduced by
commit b32cecb46bdc ("gpio: pca953x: Extract the register address mangling to single function")
but only became visible by
commit 8b9f9d4dc511 ("regmap: verify if register is writeable before writing operations")
because before, the regmap size was effectively ignored and
pca953x_writeable_register() did know to ignore REG_ADDR_AI. Still, there
were two separate cache entries created.
Since the use of REG_ADDR_AI seems to be static we can work around this
issue by simply increasing the size of the regmap to cover the "virtual"
registers with REG_ADDR_AI being set. This only means that half of the
regmap buffer will be unused.

Daniel Borkmann says:
====================
pull-request: bpf 2019-06-07
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix several bugs in riscv64 JIT code emission which forgot to clear high
32-bits for alu32 ops, from Björn and Luke with selftests covering all
relevant BPF alu ops from Björn and Jiong.
2) Two fixes for UDP BPF reuseport that avoid calling the program in case of
__udp6_lib_err and UDP GRO which broke reuseport_select_sock() assumption
that skb->data is pointing to transport header, from Martin.
3) Two fixes for BPF sockmap: a use-after-free from sleep in psock's backlog
workqueue, and a missing restore of sk_write_space when psock gets dropped,
from Jakub and John.
4) Fix unconnected UDP sendmsg hook API which is insufficient as-is since it
breaks standard applications like DNS if reverse NAT is not performed upon
receive, from Daniel.
5) Fix an out-of-bounds read in __bpf_skc_lookup which in case of AF_INET6
fails to verify that the length of the tuple is long enough, from Lorenz.
6) Fix libbpf's libbpf__probe_raw_btf to return an fd instead of 0/1 (for
{un,}successful probe) as that is expected to be propagated as an fd to
load_sk_storage_btf() and thus closing the wrong descriptor otherwise,
from Michal.
7) Fix bpftool's JSON output for the case when a lookup fails, from Krzesimir.
8) Minor misc fixes in docs, samples and selftests, from various others.
