Hi!
There is an unaddressed issue in qemu-user [1] which results in getresuid()
returning an incorrect UID due to a byte-swapping issue on sparc64.
This issue is fixed by the patch below which was suggested by Phillippe
Mathieu-Daudé, but the corresponding line [2] has not been patched yet.
Could anyone step up and fix the bug?
Thanks,
Adrian
