9ae3a8
phys_mem_alloc and its assigned values qemu_anon_ram_alloc and
9ae3a8
legacy_s390_alloc must have identical argument lists.
9ae3a8
9ae3a8
legacy_s390_alloc uses the size parameter to call mmap, so size_t is
9ae3a8
good enough for all of them.
9ae3a8
9ae3a8
This patch fixes compiler errors on i686 Linux hosts:

(cherry picked from commit 575ddeb459f622a114cbfe37d220c0519ec9c2a4)
9ae3a8
9ae3a8
Note: not directly related to this change, and we don't have
9ae3a8
to support building on i686.
9ae3a8
However this is gratitious and ugly difference from upstream,
9ae3a8
and some machines I use to test ACPI are i686, so including
9ae3a8
this here was required for testing.
