commit fa7d2e63 upstream.

For recovery, where non-dax access is needed to a given physical address
range, and testing, allow the 'force_raw' attribute to override the
default establishment of a dev_pagemap.

Otherwise without this capability it is possible to end up with a
namespace that can not be activated due to corrupted info-block, and one
that can not be repaired due to a section collision.

commit 966d23a0 upstream.

The UEFI 2.7 specification sets expectations that the 'updating' flag is
eventually cleared. To date, the libnvdimm core has never adhered to
that protocol. The policy of the core matches the policy of other
multi-device info-block formats like MD-Software-RAID that expect
administrator intervention on inconsistent info-blocks, not automatic
invalidation.

However, some pre-boot environments may unfortunately attempt to "clean
up" the labels and invalidate a set when it fails to find at least one
"non-updating" label in the set. Clear the updating flag after set
updates to minimize the window of vulnerability to aggressive pre-boot
environments.

Ideally implementations would not write to the label area outside of
creating namespaces.

Note that this only minimizes the window, it does not close it as the
system can still crash while clearing the flag and the set can be
subsequently deleted / invalidated by the pre-boot environment.

Just like commit e2ba732a ("selftests: fib_tests: sleep after
changing carrier"), wait one second to allow linkwatch to propagate the
carrier change to the stack.

There are two sets of carrier tests. The first slept after the carrier
was set to off, and when the second set ran, it was likely that the
linkwatch would be able to run again without much delay, reducing the
likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a
loop, you will quickly notice the failures.

Sleeping on the second set of tests make the failures go away.

ARCv2 optimized memcpy uses PREFETCHW instruction for prefetching the
next cache line but doesn't ensure that the line is not past the end of
the buffer. PRETECHW changes the line ownership and marks it dirty,
which can cause data corruption if this area is used for DMA IO.

Fix the issue by avoiding the PREFETCHW. This leads to performance
degradation but it is OK as we'll introduce new memcpy implementation
optimized for unaligned memory access using.

We also cut off all PREFETCH instructions at they are quite useless
here:
 * we call PREFETCH right before LOAD instruction call.
 * we copy 16 or 32 bytes of data (depending on CONFIG_ARC_HAS_LL64)
   in a main logical loop. so we call PREFETCH 4 times (or 2 times)
   for each L1 cache line (in case of 64B L1 cache Line which is
   default case). Obviously this is not optimal.

[ Upstream commit 1062af92 ]

tmpfs has a peculiarity of accounting hard links as if they were
separate inodes: so that when the number of inodes is limited, as it is
by default, a user cannot soak up an unlimited amount of unreclaimable
dcache memory just by repeatedly linking a file.

But when v3.11 added O_TMPFILE, and the ability to use linkat() on the
fd, we missed accommodating this new case in tmpfs: "df -i" shows that
an extra "inode" remains accounted after the file is unlinked and the fd
closed and the actual inode evicted.  If a user repeatedly links
tmpfiles into a tmpfs, the limit will be hit (ENOSPC) even after they
are deleted.

Just skip the extra reservation from shmem_link() in this case: there's
a sense in which this first link of a tmpfile is then cheaper than a
hard link of another file, but the accounting works out, and there's
still good limiting, so no need to do anything more complicated.

Workaround this issue by using CONFIG_SMP=n specific lru_add_drain_all

the workqueue as the draining is going to happen on the local cpu.  So
alias lru_add_drain_all to lru_add_drain which does all the necessary

Commit 48299769 ("ARM: tegra: Fix unit_address_vs_reg DTC warnings
for /memory") inadventently broke device tree ABI by adding a unit-
address to the "/memory" node because the device tree compiler flagged
the missing unit-address as a warning.

Tegra124 Chromebooks (a.k.a. Nyan) use a bootloader that relies on the
full name of the memory node in device tree being exactly "/memory". It
can be argued whether this was a good decision or not, and some other
bootloaders (such as U-Boot) do accept a unit-address in the name of the
node, but the device tree is an ABI and we can't break existing setups
just because the device tree compiler considers it bad practice to omit
the unit-address nowadays.

This partially reverts the offending commit and restores device tree ABI
compatibility.

[ Upstream commit 9addc927 ]

The assumption that the maximum size of a syn packet is 128 bytes
is wrong. Tunneling headers were not accounted for.
Allocate buffers large enough for mtu.

RING_CONTROL reg was not written due to wrong address, hence all
the subsequent ring flush was timing out.

[ Upstream commit 660899dd ]

After moving an XFRM interface to another namespace it stays associated
with the original namespace (net in `struct xfrm_if` and the list keyed
with `xfrmi_net_id`), allowing processes in the new namespace to use
SAs/policies that were created in the original namespace.  For instance,
this allows a keying daemon in one namespace to establish IPsec SAs for
other namespaces without processes there having access to the keys or IKE
credentials.

This worked fine for outbound traffic, however, for inbound traffic the
lookup for the interfaces and the policies used the incorrect namespace
(the one the XFRM interface was moved to).

[ Upstream commit c17abcfa ]

Fix the mismatch between the "sdxc_d13_1_a" pin group definition from
meson8b_cbus_groups and the entry in sdxc_a_groups ("sdxc_d0_13_1_a").
This makes it possible to use "sdxc_d13_1_a" in device-tree files to
route the MMC data 1..3 pins to GPIOX_1..3.

We assume in the bcm_sf2 driver that the DSA master network device
supports ethtool_ops::{get,set}_wol operations, which is not a given.
Avoid de-referencing potentially non-existent function pointers and
check them as we should.
