bfad978116 regmap: provide helpers for simple bit operations
In many instances regmap_update_bits() is used for simple bit setting
and clearing. In these cases the last argument is redundant and we can
hide it with a static inline function.

This adds three new helpers for simple bit operations: set_bits,
clear_bits and test_bits (the last one defined as a regular function).

1806c13dc2 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
xdp_umem.c had overlapping changes between the 64-bit math fix
for the calculation of npgs and the removal of the zerocopy
memory type which got rid of the chunk_size_nohdr member.

The mlx5 Kconfig conflict is a case where we just take the
net-next copy of the Kconfig entry dependency as it takes on
the ESWITCH dependency by one level of indirection which is
what the 'net' conflicting change is trying to ensure.

3b3ec3d52e mac80211: check the correct bit for EMA AP
An AP supporting EMA (Enhanced Multi-BSSID advertisement) should set
bit 83 in the extended capabilities IE (9.4.2.26 in the 802.11ax D5 spec).
So the *3rd* bit of the 10th byte should be checked.
Also, in one place, the wrong byte was checked.
(cfg80211_find_ie returns a pointer to the beginning of the IE,
 so the data really starts at ie[2], so the 10th byte
 should be ie[12]. To avoid this confusion, use cfg80211_find_elem
 instead).

7c6d2ecbda net: be more gentle about silly gso requests coming from user
Recent change in virtio_net_hdr_to_skb() broke some packetdrill tests.

When --mss=XXX option is set, packetdrill always provide gso_type & gso_size
for its inbound packets, regardless of packet size.

	if (packet->tcp && packet->mss) {
		if (packet->ipv4)
			gso.gso_type = VIRTIO_NET_HDR_GSO_TCPV4;
		else
			gso.gso_type = VIRTIO_NET_HDR_GSO_TCPV6;
		gso.gso_size = packet->mss;
	}

Since many other programs could do the same, relax virtio_net_hdr_to_skb()
to no longer return an error, but instead ignore gso settings.

This keeps Willem intent to make sure no malicious packet could
reach gso stack.

Note that TCP stack has a special logic in tcp_set_skb_tso_segs()
to clear gso_size for small packets.

6988f31d55 mm: remove VM_BUG_ON(PageSlab()) from page_mapcount()
Replace superfluous VM_BUG_ON() with comment about correct usage.

Technically reverts commit 1d148e218a ("mm: add VM_BUG_ON_PAGE() to
page_mapcount()"), but context lines have changed.

Function isolate_migratepages_block() runs some checks out of lru_lock
when choose pages for migration.  After checking PageLRU() it checks
extra page references by comparing page_count() and page_mapcount().
Between these two checks page could be removed from lru, freed and taken
by slab.

As a result this race triggers VM_BUG_ON(PageSlab()) in page_mapcount().
Race window is tiny.  For certain workload this happens around once a
year.

    page:ffffea0105ca9380 count:1 mapcount:0 mapping:ffff88ff7712c180 index:0x0 compound_mapcount: 0

The code in isolate_migratepages_block() was added in commit

adding VM_BUG_ON into page_mapcount().

This race has been predicted in 2015 by Vlastimil Babka (see link
below).

f17936993a fanotify: turn off support for FAN_DIR_MODIFY
FAN_DIR_MODIFY has been enabled by commit 44d705b037 ("fanotify:
report name info for FAN_DIR_MODIFY event") in 5.7-rc1. Now we are
planning further extensions to the fanotify API and during that we
realized that FAN_DIR_MODIFY may behave slightly differently to be more
consistent with extensions we plan. So until we finalize these
extensions, let's not bind our hands with exposing FAN_DIR_MODIFY to
userland.

6b646a7e4a net/mlx5: Add ability to read and write ECE options
The end result of RDMA-CM ECE handshake is ECE options, which is
needed to be used while configuring data QPs. Such options can
come in any QP state, so add in/out fields to set and query
ECE options.

OUT fields:
* create_qp() - default ECE options for that type of QP.
* modify_qp() - enabled ECE options after QP state transition.

IN fields:
* create_qp() - create QP with this ECE option.
* modify_qp() - requested options. For unconnected QPs, the FW
will return an error if ECE is already configured with any options
that not equal to previously set.

396fba0a59 cfg80211: Replace zero-length array with flexible-array
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

100GbE Intel Wired LAN Driver Updates 2020-05-22

This series contains updates to virtchnl and the ice driver.

Geert Uytterhoeven fixes a data structure alignment issue in the
virtchnl structures.

Henry adds Flow Director support which allows for the redirection on
ntuple rules over six patches.  Initially Henry adds the initial
infrastructure for Flow Director, and then later adds IPv4 and IPv6
support, as well as being able to display the ntuple rules.

Bret add Accelerated Receive Flow Steering (aRFS) support which is used
to steer receive flows to a specific queue.  Fixes a transmit timeout
when the VF link transitions from up/down/up because the transmit and
receive queue interrupts are not enabled as part of VF's link up.  Fixed
an issue when the default VF LAN address is changed and after reset the
PF will attempt to add the new MAC, which fails because it already
exists. This causes the VF to be disabled completely until it is removed
and enabled via sysfs.

Anirudh (Ani) makes a fix where the ice driver needs to call set_mac_cfg
to enable jumbo frames, so ensure it gets called during initialization
and after reset.  Fix bad register reads during a register dump in
ethtool by removing the bad registers.

Paul fixes an issue where the receive Malicious Driver Detection (MDD)
auto reset message was not being logged because it occurred after the VF
reset.

Victor adds a check for compatibility between the Dynamic Device
Personalization (DDP) package and the NIC firmware to ensure that
everything aligns.

Jesse fixes a administrative queue string call with the appropriate
error reporting variable.  Also fixed the loop variables that are
comparing or assigning signed against unsigned values.
