Fix a bug in iwx(4) Tx done interrupt processing. Clear the byte-count for the correct frame while taking frames off the ring. This should fix some 'fatal firmware errors' seen under load, and prevent memory corruption: The device could access an mbuf we have freed, but which is still marked as used in the byte count table and which still has a DMA address in its Tx descriptor. Problem observed by mlarkin with NFS while testing my patch for Tx aggregation support. |

| message |
Zero out iwx(4) Tx descriptors of frames which are done. This will hopefully prevent the device from ever writing to the former DMA address of a buffer which has been taken off the Tx ring. As far as I understand, the Linux driver unmaps (parts of) Tx descriptors that are done. We use a static DMA mapping for the entire descriptor array, so unmapping is not an option for us. Tested by several as part of my Tx aggregation support patch. |

Change the scope of the locking in pmap_extract() to prevent a race between walking the page tables and another thread calling pmap_remove() that ends up removing a page table page. tested by sthen@ ok deraadt@, mpi@ |

Don't set the highspeed bit on bcm2835-sdhci sdhc(4) controllers. Same approach as on Linux and NetBSD. This fixes bwfm(4) Wi-Fi on the Raspberry Pi 3 Model B Plus. help and ok kettenis@ |

Identify TPM2.0 devices and perform the 2.0-specific "suspend" command (researched by mlarkin). With this, and the latest BIOS which added S3, the lenovo x1r9 and x1nano can resume. ok kettenis mlarkin |
