[Qemu-devel] [PATCH] Fix size checking in load_image_targphys to accept max_size > INT_MAX |

commit 17df768c1e4580f03301d18ea938d3557d441911
load_image_targphys() should enforce the max size
caused some problems with external kernel and specific ram sizes on s390:
We load the external kernel with
[...]
kernel_size = load_image_targphys(kernel_filename, 0, ram_size);
[...]
Since load_image_targphys is declared as taking an int for max_sz, this will
fail for ram sizes > INT_MAX.
Lets change the max_sz parameter to a uint64_t.
