[Qemu-devel] [PATCH 1/3] exec.c: Pass correct pointer type to qemu_ram_ptr_length |

From: Peter Maydell <address@hidden>
Commit e3127ae0 introduced a problem where we're passing a
hwaddr* to qemu_ram_ptr_length() but it wants a ram_addr_t*;
this will cause problems on 32 bit hosts and in any case
provokes a clang warning on MacOSX:
CC arm-softmmu/exec.o
exec.c:2164:46: warning: incompatible pointer types passing 'hwaddr *'
(aka 'unsigned long long *') to parameter of type 'ram_addr_t *'
(aka 'unsigned long *')
[-Wincompatible-pointer-types]
return qemu_ram_ptr_length(raddr + base, plen);
^~~~
exec.c:1392:63: note: passing argument to parameter 'size' here
static void *qemu_ram_ptr_length(ram_addr_t addr, ram_addr_t *size)
^
Since this function is only used in one place, change its
prototype to pass a hwaddr* rather than a ram_addr_t*,
rather than contorting the calling code to get the type right.
