[ Upstream commit 1f1c92139e36223b89d8140f2b72f75e79baf8bd ]
Currently, the error return code of the failure condition is lost after
using an if statement, so the test doesn't fail when it should.
Remove the if statement that separates the condition and the error code
check, so the test won't always pass.

[ Upstream commit c8d0260cdd96fdccdef0509c4160e28a1012a5d7 ]
The FDB roaming test installs a destination MAC address on the wrong
interface of an FDB database and tests whether the mirroring fails, because
packets are sent to the wrong port. The test by mistake installs the FDB
entry as local. This worked previously, because drivers were notified of
local FDB entries in the same way as of static entries. However that has
been fixed in the commit 6ab4c3117aec ("net: bridge: don't notify switchdev
for local FDB addresses"), and local entries are not notified anymore. As a
result, the HW is not reconfigured for the FDB roam, and mirroring keeps
working, failing the test.
To fix the issue, mark the FDB entry as static.

Modify the header size check in geneve6_xmit_skb and geneve_xmit_skb
to use pskb_inet_may_pull rather than pskb_network_may_pull. This fixes
two kernel selftest failures introduced by the commit introducing the
checks:
IPv4 over geneve6: PMTU exceptions
IPv4 over geneve6: PMTU exceptions - nexthop objects
It does this by correctly accounting for the fact that IPv4 packets may
transit over geneve IPv6 tunnels (and vice versa), and still fixes the
uninit-value bug fixed by the original commit.

The problem is that bnxt_show_temp() returns long but "rc" is an int
and "len" is a u32. With ternary operations the type promotion is quite
tricky. The negative "rc" is first promoted to u32 and then to long so
it ends up being a high positive value instead of a a negative as we
intended.

When the error check in ath9k_hw_read_revisions() was added, it checked for
-EIO which is what ath9k_regread() in the ath9k_htc driver uses. However,
for plain ath9k, the register read function uses ioread32(), which just
returns -1 on error. So if such a read fails, it still gets passed through
and ends up as a weird mac revision in the log output.
Fix this by changing ath9k_regread() to return -1 on error like ioread32()
does, and fix the error check to look for that instead of -EIO.

The Intel xway phys offer the possibility to deactivate the integrated

If this was set by the bootloader, it must be ensured that the
integrated LED function is enabled for all LEDs when loading the driver.
Before commit 6e2d85ec0559 ("net: phy: Stop with excessive soft reset")
the LEDs were enabled by a soft-reset of the PHY (using
genphy_soft_reset). Initialize the XWAY_MDIO_LED with it's default
value (which is applied during a soft reset) instead of adding back
the soft reset. This brings back the default LED configuration while
still preventing an excessive amount of soft resets.

Explicitly reject using pointers that are not virt_to_phys() friendly
as the source for SEV commands that are sent to the PSP. The PSP works
with physical addresses, and __pa()/virt_to_phys() will not return the
correct address in these cases, e.g. for a vmalloc'd pointer. At best,
the bogus address will cause the command to fail, and at worst lead to
system instability.
While it's unlikely that callers will deliberately use a bad pointer for
SEV buffers, a caller can easily use a vmalloc'd pointer unknowingly when
running with CONFIG_VMAP_STACK=y as it's not obvious that putting the
command buffers on the stack would be bad. The command buffers are
relative small and easily fit on the stack, and the APIs to do not
document that the incoming pointer must be a physically contiguous,

[ Upstream commit 7ad18ff6449cbd6beb26b53128ddf56d2685aa93 ]
Commit 38ec4944b593 ("gro: ensure frag0 meets IP header alignment")
did the right thing, but missed the fact that napi_gro_frags() logics
calls for skb_gro_reset_offset() *before* pulling Ethernet header
to the skb linear space.
That said, the introduced check for frag0 address being aligned to 4
always fails for it as Ethernet header is obviously 14 bytes long,
and in case with NET_IP_ALIGN its start is not aligned to 4.
Fix this by adding @nhoff argument to skb_gro_reset_offset() which
tells if an IP header is placed right at the start of frag0 or not.
This restores Fast GRO for napi_gro_frags() that became very slow
after the mentioned commit, and preserves the introduced check to
avoid silent unaligned accesses.
From v1 [0]:
- inline tiny skb_gro_reset_offset() to let the code be optimized
more efficively (esp. for the !NET_IP_ALIGN case) (Eric);
- pull in Reviewed-by from Eric.

The nftables offload parser sets FLOW_DISSECTOR_KEY_BASIC .n_proto to the
ethertype field in the ethertype frame. However:
- FLOW_DISSECTOR_KEY_BASIC .n_proto field always stores either IPv4 or IPv6
ethertypes.
- FLOW_DISSECTOR_KEY_VLAN .vlan_tpid stores either the 802.1q and 802.1ad
ethertypes. Same as for FLOW_DISSECTOR_KEY_CVLAN.
This function adjusts the flow dissector to handle two scenarios:
1) FLOW_DISSECTOR_KEY_VLAN .vlan_tpid is set to 802.1q or 802.1ad.
Then, transfer:
- the .n_proto field to FLOW_DISSECTOR_KEY_VLAN .tpid.
- the original FLOW_DISSECTOR_KEY_VLAN .tpid to the
FLOW_DISSECTOR_KEY_CVLAN .tpid
- the original FLOW_DISSECTOR_KEY_CVLAN .tpid to the .n_proto field.
2) .n_proto is set to 802.1q or 802.1ad. Then, transfer:
- the .n_proto field to FLOW_DISSECTOR_KEY_VLAN .tpid.
- the original FLOW_DISSECTOR_KEY_VLAN .tpid to the .n_proto field.

Daniel reported that with Commit 4ca234a9cbd7 ("powerpc/smp: Stop
updating cpu_core_mask") QEMU was unable to set single NUMA node SMP
topologies such as:
-smp 8,maxcpus=8,cores=2,threads=2,sockets=2
i.e he expected 2 sockets in one NUMA node.
The above commit helped to reduce boot time on Large Systems for
example 4096 vCPU single socket QEMU instance. PAPR is silent on
having more than one socket within a NUMA node.
cpu_core_mask and cpu_cpu_mask for any CPU would be same unless the
number of sockets is different from the number of NUMA nodes.
One option is to reintroduce cpu_core_mask but use a slightly
different method to arrive at the cpu_core_mask. Previously each CPU's
chip-id would be compared with all other CPU's chip-id to verify if
both the CPUs were related at the chip level. Now if a CPU 'A' is
found related / (unrelated) to another CPU 'B', all the thread
siblings of 'A' and thread siblings of 'B' are automatically marked as
related / (unrelated).
Also if a platform doesn't support ibm,chip-id property, i.e its
cpu_to_chip_id returns -1, cpu_core_map holds a copy of
cpu_cpu_mask().

Mirror commit aeba3731b150 ("powerpc/pci: Fix IO space breakage after
of_pci_range_to_resource() change").
Most MIPS platforms do not define PCI_IOBASE, nor implement
pci_address_to_pio(). Moreover, IO_SPACE_LIMIT is 0xffff for most MIPS
platforms. of_pci_range_to_resource passes the _start address_ of the IO
range into pci_address_to_pio, which then checks it against
IO_SPACE_LIMIT and fails, because for MIPS platforms that use
pci-legacy (pci-lantiq, pci-rt3883, pci-mt7620), IO ranges start much
higher than 0xffff.
In fact, pci-mt7621 in staging already works around this problem, see
commit 09dd629eeabb ("staging: mt7621-pci: fix io space and properly set
resource limits")
So just stop using of_pci_range_to_resource, which does not work for
MIPS.
