Merge tag 'powerpc-5.4-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:
 "Our recent cleanup of EEH led to an oops on bare metal machines when
  the cxl (CAPI) driver creates virtual devices for an attached FPGA
  accelerator.

  The "secure virtual machine" support we added in v5.4 had a bug if the
  kernel was relocated (moved during boot), in those cases the signature
  of the kernel text wouldn't verify and the Ultravisor would refuse to
  run the VM.

  A recent change to disable interrupts before calling
  arch_cpu_idle_dead() caused a WARN_ON() in our bare metal CPU offline
  code to always trigger.

  The KUAP (SMAP) support we added for 32-bit Book3S had a bug if the
  address range crossed a segment (256MB) boundary which could lead to
  spurious faults.

  Thanks to: Christophe Leroy, Frederic Barrat, Michael Anderson,
  Nicholas Piggin, Sam Bobroff, Thiago Jung Bauermann"

====================
fix BPF offload related bugs

test_offload.py catches some recently added bugs.

First of a bug in test_offload.py itself after recent changes
to netdevsim is fixed.

Second patch fixes a bug in cls_bpf, and last one addresses
a problem with the recently added XDP installation optimization.

net: fix installing orphaned programs

When netdevice with offloaded BPF programs is destroyed
the programs are orphaned and removed from the program
IDA - their IDs get released (the programs may remain
accessible via existing open file descriptors and pinned
files). After IDs are released they are set to 0.

This confuses dev_change_xdp_fd() because it compares
the __dev_xdp_query() result where 0 means no program
with prog->aux->id where 0 means orphaned.

dev_change_xdp_fd() would have incorrectly returned success
even though it had not installed the program.

Since drivers already catch this case via bpf_offload_dev_match()
let them handle this case. The error message drivers produce in
this case ("program loaded for a different device") is in fact
correct as the orphaned program must had to be loaded for a
different device.

r8169: fix wrong PHY ID issue with RTL8168dp

As reported in [0] at least one RTL8168dp version has problems
establishing a link. This chip version has an integrated RTL8211b PHY,
however the chip seems to report a wrong PHY ID, resulting in a wrong
PHY driver (for Generic Realtek PHY) being loaded.
Work around this issue by adding a hook to r8168dp_2_mdio_read()
for returning the correct PHY ID.

net: dsa: bcm_sf2: Fix IMP setup for port different than 8

Since it became possible for the DSA core to use a CPU port different
than 8, our bcm_sf2_imp_setup() function was broken because it assumes
that registers are applicable to port 8. In particular, the port's MAC
is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS
bits if we are not configured for port 8.
