  PCI: aardvark: Fix kernel panic during PIO transfer (2021-06-18 10:32:35 -0500)


I rebased these this morning to add a tested-by.  The commits
themselves have all been in linux-next, though not for as long
as I'd like.

----------------------------------------------------------------
PCI fixes:

  - Clear 64-bit flag for host bridge windows below 4GB to fix a resource
    allocation regression added in -rc1 (Punit Agrawal)

  - Fix tegra194 MCFG quirk build regressions added in -rc1 (Jon Hunter)

  - Avoid secondary bus resets on TI KeyStone C667X devices (Antti
    Järvinen)

  - Avoid secondary bus resets on some NVIDIA GPUs (Shanker Donthineni)

  - Work around FLR erratum on Huawei Intelligent NIC VF (Chiqijun)

  - Avoid broken ATS on AMD Navi14 GPU (Evan Quan)

  - Trust Broadcom BCM57414 NIC to isolate functions even though it
    doesn't advertise ACS support (Sriharsha Basavapatna)

  - Work around AMD RS690 BIOSes that don't configure DMA above 4GB (Mikel
    Rychliski)

  - Fix panic during PIO transfer on Aardvark controller (Pali Rohár)
