Configuring QEMU with:
configure --cc=clang --target-list=s390x-softmmu
And compiling it using a 32 bit machine leads to:
hw/s390x/s390-virtio-ccw.c:175:27: error: implicit conversion from
'unsigned long long' to 'ram_addr_t' (aka 'unsigned int') changes value
from 8796091973632 to 4293918720 [-Werror,-Wconstant-conversion]
chunk = MIN(size, KVM_SLOT_MAX_BYTES);
~ ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~
Fix the missmatch by declaring the 'chunk' variable as uint64_t.
