acpi_pci: Add quirk for DELAY-after-EJ0
On some EC2 instances, there is a race between removing a device from
the system and making the PCI bus stop reporting the presence of the
device. As a result, a PCI BUS_RESCAN performed immediately after
the _EJ0 method returns "sees" the device which is being ejected, which
then causes problems later (e.g. we won't recognize a new device being
plugged into that slot because we never knew it was vacant).
On other operating systems the bus is synchronously marked as needing
to be rescanned but the rescan does not occur until O(1) seconds later.
Create a new ACPI_Q_DELAY_BEFORE_EJECT_RESCAN quirk and set it in EC2
AMIs, and add a 10 ms DELAY between _EJ0 and BUS_RESCAN when tht quirk
is set.

Enable LLVM_BINUTILS by default
Starting in 2014 FreeBSD migrated from GNU binutils to ELF Tool Chain
tools. At that time there were no usable LLVM versions of those tools,
but they have been developing rapidly since then. Migrate to LLVML's
tools for both functionality and maintainability reasons.
This will eventually support the use of link-time optimization (LTO) in
the FreeBSD base system. LTO runs optimization passes over the entire
executable (or library) at link time and thus allows for more effective
optimization than when performed on individual compilation units.
When using LTO object files (.o) including those contained in static
library archives (.a) contain LLVM IR bitcode rather than target
object code. This means that utilities that operate on object files
need to support LLVM IR.
As with ELF Tool Chain the LLVM tools aim for command line and output
format compatibility with GNU binutils, although there are a few minor

LinuxKPI: always use contig allocations in linux_alloc_kmem()
In linux_alloc_kmem() [used by *get_page*()] we always at least allocate
PAGE_SIZE and we want the allocation to be contiguous so it can be passed
to DMA. Always use kmem_alloc_contig() and only change the low argument
depending on the GFP_DMA32 flag being given or not.

LinuxKPI: make __kmalloc() play by the rules
According to Documentation/core-api/dma-api.rst kmalloc() is supposd
to provide physically contiguous memory. [1]
In order to guarantee that allocations are contiguous even if using
PAGE_SIZE or larger check the size and use contigmalloc if needed.
This makes use of 9e6544dd6e02 (and following) allowing free(9) to
also work for contigmalloced memory.
