44ee69ea16 s390x: Fix spelling errors
Fix typos (discovered with the 'codespell' utility).
Note: Though "migrateable" still seems to be a valid spelling, we change
it to "migratable" since this is the way more common spelling here.

f8333de279 target/s390x/tcg: SPX: check validity of new prefix
According to the architecture, SET PREFIX must try to access the new
prefix area and recognize an addressing exception if the area is not
accessible.
For qemu this check prevents a crash in cpu_map_lowcore after an
inaccessible prefix area has been set.

6b01606f0e s390x/tcg: fix and optimize SPX (SET PREFIX)
We not only invalidate the translation of the range 0x0-0x2000, we also
invalidate the translation of the new prefix range and the translation
of the old prefix range -- because real2abs would return different
results for all of these ranges when changing the prefix location.

This fixes the kvm-unit-tests "edat" test that just hangs before this
patch because we end up clearing the new prefix area instead of the old
prefix area.

While at it, let's not do anything in case the prefix doesn't change.

c9274b6bf0 target/s390x: start moving TCG-only code to tcg/
move everything related to translate, as well as HELPER code in tcg/

mmu_helper.c stays put for now, as it contains both TCG and KVM code.

After the reshuffling, update MAINTAINERS accordingly.
Make use of the new directory:

target/s390x/tcg/
