Pull powerpc fixes from Michael Ellerman:
"A couple of weeks of fixes.
There's one fix for an oops on Power9 machines with Open CAPI
adapters.
And a fix for probable memory corruption in some of the new NPU code,
caught by smatch though and not seen in the wild.
Plus a few other minor fixes.
There's one non-fix which is the perf_regs change. That was sent
during the merge window but I accidentally only merged the first of
two patches in the series. It's been in linux-next so hopefully
doesn't conflict with anything in acme's tree.
Thanks to: Alexey Kardashevskiy, Andrew Donnellan, Breno Leitao,
Christian Lamparter, Christophe Leroy, Dan Carpenter, Frederic Barrat,
Greg Kurz, Jason A. Donenfeld, Madhavan Srinivasan"

Pull ACPI fixes from Rafael Wysocki:
"These fix an ACPI initialization ordering issue introduced in the 4.17
time frame and causing functional problems to appear on multiple
systems and fix some fallout of the recent change to enable building
kernels with ACPI support and without PCI.
Specifics:
- Restore the ACPI initialization ordering changed implicitly by the
module-level AML handling rework during the 4.17 development cycle
that caused the EC address space handler based on information from
ECDT to be set up before loading AML definition blocks, making it
effectively not accessible by AML on some systems that don't work
as expected any more (Rafael Wysocki).
- Add direct dependencies on PCI to Kconfig in multiple places for
code that depends on both ACPI and PCI, but the PCI dependency was
implicitly satisfied by the ACPI dependency before, to prevent
invalid configurations from being created, for example by
randconfig (Sinan Kaya)"

The cleaner thread usually takes care of delayed iputs, with the
exception of the btrfs_end_transaction_throttle path. Delaying iputs
means we are potentially delaying the eviction of an inode and it's
respective space. The cleaner thread only gets woken up every 30
seconds, or when we require space. If there are a lot of inodes that
need to be deleted we could induce a serious amount of latency while we
wait for these inodes to be evicted. So instead wakeup the cleaner if
it's not already awake to process any new delayed iputs we add to the
list. If we suddenly need space we will less likely be backed up
behind a bunch of inodes that are waiting to be deleted, and we could
possibly free space before we need to get into the flushing logic which
will save us some latency.

Delayed iputs means we can have final iputs of deleted inodes in the
queue, which could potentially generate a lot of pinned space that could
be free'd. So before we decide to commit the transaction for ENOPSC
reasons, run the delayed iputs so that any potential space is free'd up.
If there is and we freed enough we can then commit the transaction and
potentially be able to make our reservation.

If we flip read-only before we initiate writeback on all dirty pages for
ordered extents we've created then we'll have ordered extents left over
on umount, which results in all sorts of bad things happening. Fix this
by making sure we wait on ordered extents if we have to do the aborted
transaction cleanup stuff.

This reverts commit e73e81b6d0114d4a303205a952ab2e87c44bd279.
This patch causes a few problems:
- adds latency to btrfs_finish_ordered_io
- as btrfs_finish_ordered_io is used for free space cache, generating
more work from btrfs_btree_balance_dirty_nodelay could end up in the
same workque, effectively deadlocking

Eventually, we have every process in the system waiting on
balance_dirty_pages(), and nobody is able to make progress on page
writeback.
The original patch tried to fix an OOM condition, that happened on 4.4 but no
success reproducing that on later kernels (4.19 and 4.20). This is more likely
a problem in OOM itself.

The XGBE hardware has support for performing MDIO operations using an
MDIO command request. The driver mistakenly uses the mdio port address
as the MDIO command request device address instead of the MDIO command
request port address. Additionally, the driver does not properly check
for and create a clause 45 MDIO command.
Check the supplied MDIO register to determine if the request is a clause
45 operation (MII_ADDR_C45). For a clause 45 operation, extract the device
address and register number from the supplied MDIO register and use them
to set the MDIO command request device address and register number fields.
For a clause 22 operation, the MDIO request device address is set to zero
and the MDIO command request register number is set to the supplied MDIO
register. In either case, the supplied MDIO port address is used as the
MDIO command request port address.

The skb header should be set to ethernet header before using
is_skb_forwardable. Because the ethernet header length has been
considered in is_skb_forwardable(including dev->hard_header_len
length).
To reproduce the issue:
1, add 2 ports on linux bridge br using following commands:
$ brctl addbr br
$ brctl addif br eth0
$ brctl addif br eth1
2, the MTU of eth0 and eth1 is 1500
3, send a packet(Data 1480, UDP 8, IP 20, Ethernet 14, VLAN 4)
from eth0 to eth1
So the expect result is packet larger than 1500 cannot pass through
eth0 and eth1. But currently, the packet passes through success, it
means eth1's MTU limit doesn't take effect.

Vhost dirty page logging API is designed to sync through GPA. But we
try to log GIOVA when device IOTLB is enabled. This is wrong and may
lead to missing data after migration.
To solve this issue, when logging with device IOTLB enabled, we will:
1) reuse the device IOTLB translation result of GIOVA->HVA mapping to
get HVA, for writable descriptor, get HVA through iovec. For used
ring update, translate its GIOVA to HVA
2) traverse the GPA->HVA mapping to get the possible GPA and log
through GPA. Pay attention this reverse mapping is not guaranteed
to be unique, so we should log each possible GPA in this case.
This fix the failure of scp to guest during migration. In -next, we
will probably support passing GIOVA->GPA instead of GIOVA->HVA.

Since commit cb9f1b783850, scapy (which uses an AF_PACKET socket in
SOCK_RAW mode) is unable to send a basic icmp packet over a sit tunnel:
Here is a example of the setup:
$ ip link set ntfp2 up
$ ip addr add 10.125.0.1/24 dev ntfp2
$ ip tunnel add tun1 mode sit ttl 64 local 10.125.0.1 remote 10.125.0.2 dev ntfp2
$ ip addr add fd00:cafe:cafe::1/128 dev tun1
$ ip link set dev tun1 up
$ ip route add fd00:200::/64 dev tun1
$ scapy
>>> p = []
>>> p += IPv6(src='fd00:100::1', dst='fd00:200::1')/ICMPv6EchoRequest()
>>> send(p, count=1, inter=0.1)
>>> quit()
$ ip -s link ls dev tun1 | grep -A1 "TX.*errors"
TX: bytes packets errors dropped carrier collsns
0 0 1 0 0 0
The problem is that the network offset is set to the hard_header_len of the
output device (tun1, ie 14 + 20) and in our case, because the packet is
small (48 bytes) the pskb_inet_may_pull() fails (it tries to pull 40 bytes
(ipv6 header) starting from the network offset).
This problem is more generally related to device with variable hard header
length. To avoid a too intrusive patch in the current release, a (ugly)
workaround is proposed in this patch. It has to be cleaned up in net-next.

Recent changes (especially 05cd271fd61a ("cls_flower: Support multiple
masks per priority")) in the fl_flow_mask structure grow it and its
current size e.g. on x86_64 with defconfig is 760 bytes and more than
1024 bytes with some debug options enabled. Prior the mentioned commit
its size was 176 bytes (using defconfig on x86_64).
With regard to this fact it's reasonable to allocate this structure
dynamically in fl_change() to reduce its stack size.

- use kzalloc() instead of kcalloc()

commit b05c950698fe ("pstore/ram: Simplify ramoops_get_next_prz()
arguments") changed update assignment in getting next persistent ram zone
by adding a check for record type. But the check always returns true since
the record type is assigned 0. And this breaks console ramoops by showing
current console log instead of previous log on warm reset and hard reset
(actually hard reset should not be showing any logs).
Fix this by having persistent ram zone type check instead of record type
check. Tested this on SDM845 MTP and dragonboard 410c.
Reproducing this issue is simple as below:
1. Trigger hard reset and mount pstore. Will see console-ramoops
record in the mounted location which is the current log.
2. Trigger warm reset and mount pstore. Will see the current
console-ramoops record instead of previous record.
