by another quirk that enabled the HDA device (Lyude Paul)

PCI: Reset both NVIDIA GPU and HDA in ThinkPad P50 workaround
vfio_pci_enable() saves the device's initial configuration information
with the intent that it is restored in vfio_pci_disable(). However,
the commit referenced in Fixes: below replaced the call to
__pci_reset_function_locked(), which is not wrapped in a state save
and restore, with pci_try_reset_function(), which overwrites the
restored device state with the current state before applying it to the
device. Reinstate use of __pci_reset_function_locked() to return to
the desired behavior.

When fw fatal error occurs, poll health() first detects and reports on a
fw error. Afterwards, it detects and reports on the fw fatal error
itself.
That can cause a long delay in fw fatal error handling which waits in a
queue for the fw error handling to be finished. The fw error handle will
try asking for fw core dump command while fw in fatal state may not
respond and driver will wait for command timeout.
Changing the flow to detect and handle first fw fatal errors and only if
no fatal error detected look for a fw error to handle.

Driver waits after issuing a reset. When a reset takes too long a driver
gives up. Implemented by invoking PF reset in a loop. After defined
number of unsuccessful PF reset trials it returns error.
Without this patch PF reset fails when NIC is in recovery mode.
So make i40e_set_mac_type() public. i40e driver requires i40e_set_mac_type()
to be public. It is required for recovery mode handling. Without this patch

The functions i40e_aq_get_phy_abilities_resp() and i40e_set_fc() both
have giant structure on the stack, which makes each one use stack frames
larger than 500 bytes.
As clang decides one function into the other, we get a warning for
exceeding the frame size limit on 32-bit architectures:
drivers/net/ethernet/intel/i40e/i40e_common.c:1654:23: error: stack frame size of 1116 bytes in function 'i40e_set_fc' [-Werror,-Wframe-larger-than=]
When building with gcc, the inlining does not happen, but i40e_set_fc()
calls i40e_aq_get_phy_abilities_resp() anyway, so they add up on the
kernel stack just as much.
The parts that actually use large stacks don't overlap, so make sure
each one is a separate function, and mark them as noinline_for_stack to
prevent the compilers from combining them again.

According to PSR2_CTL definition in BSpec there is only one instance
of PSR2_CTL. Platforms gen < 12 with EDP transcoder only support PSR2
on TRANSCODER_EDP while on TGL PSR2 is only supported by
TRANSCODER_A.
Since BDW PSR is allowed on any port, but we need to restrict by
transcoder.
v8: Renamed _psr2_supported_in_trans() to psr2_supported() (Lucas)
v9: Renamed psr2_supported() to transcoder_has_psr2() (Ville)

PSR registers are a mess, some have the full address while others just
have the additional offset from psr_mmio_base.
For BDW+ psr_mmio_base is nothing more than TRANSCODER_EDP_OFFSET +
0x800 and using it makes more difficult for people with an PSR
register address or PSR register name from from BSpec as i915 also
don't match the BSpec names.
For HSW psr_mmio_base is _DDI_BUF_CTL_A + 0x800 and PSR registers are
only available in DDIA.
Other reason to make relative to transcoder is that since BDW every
transcoder have PSR registers, so in theory it should be possible to
have PSR enabled in a non-eDP transcoder.
So for BDW+ we can use _TRANS2() to get the register offset of any
PSR register in any transcoder while for HSW we have _HSW_PSR_ADJ
that will calculate the register offset for the single PSR instance,
noting that we are already guarded about trying to enable PSR in other
port than DDIA on HSW by the 'if (dig_port->base.port != PORT_A)' in
intel_psr_compute_config(), this check should only be valid for HSW
and will be changed in future.
PSR2 registers and PSR_EVENT was added after Haswell so that is why
_PSR_ADJ() is not used in some macros.
The only registers that can not be relative to transcoder are
PSR_IMR and PSR_IIR that are not relative to anything, so keeping it
hardcoded. That changed for TGL but it will be handled in another
patch.
Also removing BDW_EDP_PSR_BASE from GVT because it is not used as it
is the only PSR register that GVT have.
v5:
- Macros changed to be more explicit about HSW (Dhinakaran)
- Squashed with the patch that added the tran parameter to the
macros (Dhinakaran)
v6:
- Checking for interruption errors after module reload in the
transcoder that will be used (Dhinakaran)
- Using lowercase to the registers offsets
v7:
- Removing IS_HASWELL() from registers macros(Jani)

Add NL80211_CMD_UPDATE_FT_IES to supported commands. In mac80211 drivers,
this can be implemented via existing NL80211_CMD_AUTHENTICATE and
NL80211_ATTR_IE, but non-mac80211 drivers have a separate command for
this. A driver supports FT if it either is mac80211 or supports this
command.

Currently the for-loop will spin forever if variable supported is
non-zero because supported is never changed. Fix this by adding in
the missing right shift of supported.
