After the introduction of FOLL_SAME_FILE we no longer require vmas for any
invocation of pin_user_pages(), so eliminate this parameter from the
function and all callers.
This clears the way to removing the vmas parameter from GUP altogether.

Tell the generic BPF code that the JIT should be enabled by default,
rather than the interpreter. Most distros use CONFIG_BPF_JIT_ALWAYS_ON=y
anyway, so this just updates upstream to more closely match that.

Traditionally on powerpc servers PREEMPT_NONE was used, but these days
multiple distros are building with PREEMPT_VOLUNTARY - Ubuntu, Fedora &
CentOS all enable it.
So update the upstream config to reflect that, and get test coverage
before code hits the distros.

Fedora enables DEBUG_VM, which has led to occasions where a VM_BUG_ON()
is not caught by upstream testing, but rather is first found in Fedora,
which is not how it's meant to be.

command line, so should not add much overhead in

Incorporate the generic kvm_guest.config into the powerpc guest configs,
ppc64[le]_guest_defconfig.
This brings in some useful options, in particular 9P support, and also
means future additions to the generic file will be automatically picked
up by the powerpc configs.
