It is reported that failed randconfig runs are missing the config file
which makes debugging impossible. Fix this by moving the line that
copies the config file before the build is executed.

This patch reverts eight patches from staging.
The offending patch is the one that introduced libxl_pci_bdf (last one
in the list). The rest depend on that patch so they are also reverted.

It is reported that [] was removed by autoconf, which caused the

Implement L0 assisted TLB flush for Xen on Hyper-V. It takes advantage
of several hypercalls:
* HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST
* HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST_EX
* HVCALL_FLUSH_VIRTUAL_ADDRESS_SPACE
* HVCALL_FLUSH_VIRTUAL_ADDRESS_SPACE_EX
Pick the most efficient hypercall available.

Implement a basic hook for L0 assisted TLB flush. The hook needs to
check if prerequisites are met. If they are not met, it returns an error
number to fall back to native flushes.
Introduce a new variable to indicate if hypercall page is ready.

Hyper-V's L0 assisted flush has fine-grained control over what gets
flushed. We need all the flags available to make the best decisions
possible.
No functional change because Xen's implementation doesn't care about
what is passed to it.
