Instead of panicking when parsing an invalid ACPI SRAT table,
just ignore it, effectively disabling NUMA.

Save the value of the IOV control and page size registers and restore
them (along with the VF count) in pci_cfg_save/pci_cfg_restore. This
ensures ARI remains enabled if a PF driver resets itself during the
PCI_IOV_INIT callback. This might also properly restore SRIOV state
across suspend/resume.

While here, check if ARI was enabled by re-reading the config register
after writing it and return an error if the write fails.

Add CRC/MOVECRC operations, as well as the TEST and STORE variants.
With these operations, a CRC32C can be computed over one or more
descriptors' source data. When the STORE operation is encountered, the
accumulated CRC32C is emitted to memory. A TEST operations triggers an
IOAT channel error if the accumulated CRC32C does not match one in
memory.
These operations are not exposed through any API yet.

The IOAT engine can only address the low 40 bits (1 TB) of physmem via
the 'next descriptor' pointer. Restrict acceptable range given to
bus_dma_tag_create to match.

Not sure why the platform hypercall was disabled on i386, just enable it in

It will be used for the upcoming LRO hash table initialization.
And probably will be useful in other cases, when M_WAITOK can't
be used.

pci_remap_msix() can be used to alter the mapping of allocated
MSI-X vectors to the MSI-X table. The code had an off by one error
when adding the IRQ resources after performing a remap. This was
fatal for any vectors in the table that used the "last" valid IRQ as
those vectors were assigned a garbage IRQ value.

macro. Adjust the buffer clipping code to work as expected.
This prevented a number of machines in the FreeBSD.org cluster from
booting due to "ZFS: i/o error - all block copies unavailable"
after an unclean shutdown.
* Break out the 'g' phy code;
* Break out the debugging bits into a separate source file, since
some debugging prints are done in the phy code;
* Make some more chip methods in if_bwn.c public.
This brings the size of if_bwn.c down to 6,805 lines which is now
approaching managable.
This (and eventually migrating the other PHY code out) is in preparation
for adding the 11n PHY. No, the 11ac PHY (for the BCM4260 softmac part) isn't
yet open source, so we can't grow that. Yet.
This trims ~3,700 lines of code from if_bwn.c, bringing it down to a slightly
less crazy sounding 10,446 lines of code.
* Change x/a to work similar to gdb. The content of the memory is
treated as an address, printed symbolically and the address is advanced.
This way you can x/a <stack_address> and then just hit return a bunch
of times to locate useful data on the stack.
* Add x/p. The content of the memory is treated as an address and
printed as hex.
This is based on the similar commit from DragonFlyBSD without the
cosmetic changes.

This patch adds support for restoring backlight after resume and adds models
Macbook3,1
MacbookAir5,1
MacbookAir5,2
It also incorporates fixes for bug #175260, bug #203610 and bug #203512
so those can be closed if this patch is applied.
