Package: qemu-user
Version: 1:3.1+dfsg-2
Severity: important
Tags: patch
On sparc (only) Linux defines timeval::tv_usec with type int, not
long. However qemu-user's definition of struct target_timeval uses
abi_long unconditionally. This results in the syscall translation
layer effectively multiplying tv_usec by 2**32. All sparc syscalls
passing non-zero values for this field fail with -EINVAL. The
following patch seems to fix this.
