Merge branch 'iomap-write' into linux-gfs2/for-next

Pull in the gfs2 iomap-write changes: Tweak the existing code to
properly support iomap write and eliminate an unnecessary special case
in gfs2_block_map. Implement iomap write support for buffered and
direct I/O. Simplify some of the existing code and eliminate code that
is no longer used:

gfs2: Remove gfs2_write_{begin,end}
gfs2: iomap direct I/O support
gfs2: gfs2_extent_length cleanup
gfs2: iomap buffered write support
gfs2: Further iomap cleanups

This is based on the following changes on the xfs 'iomap-4.19-merge'
branch:

iomap: add private pointer to struct iomap
iomap: add a page_done callback
iomap: generic inline data handling
iomap: complete partial direct I/O writes synchronously
iomap: mark newly allocated buffer heads as new
fs: factor out a __generic_write_end helper

KVM: arm/arm64: Introduce kvm_arch_vcpu_run_pid_change

KVM/ARM differs from other architectures in having to maintain an
additional virtual address space from that of the host and the
guest, because we split the execution of KVM across both EL1 and
EL2.

This results in a need to explicitly map data structures into EL2
(hyp) which are accessed from the hyp code. As we are about to be
more clever with our FPSIMD handling on arm64, which stores data in
the task struct and uses thread_info flags, we will have to map
parts of the currently executing task struct into the EL2 virtual
address space.

However, we don't want to do this on every KVM_RUN, because it is a
fairly expensive operation to walk the page tables, and the common
execution mode is to map a single thread to a VCPU. By introducing
a hook that architectures can select with
HAVE_KVM_VCPU_RUN_PID_CHANGE, we do not introduce overhead for
other architectures, but have a simple way to only map the data we
need when required for arm64.

This patch introduces the framework only, and wires it up in the
arm/arm64 KVM common code.

No functional change.
