[PATCH v2 0/2] linux-user: fix print_syscall_err()

[Laurent Vivier]

This function has been introduced to manage in a generic way the error
code of the syscall in the strace output.

But it has introduced a regression regarding two previous commits:

2a7e12455c1d ("linux-user/strace.c: Correct errno printing for mmap etc")
   that intoduced the use of "-ret" rather than of "errno"
962b289ef350 ("linux-user: fix QEMU_STRACE=1 segfault")
   that checks "-ret" is a valid error number

That series fixes that.

v2: add the patch to check "-ret" is valid

Laurent Vivier (2):
  linux-user: fix the errno value in print_syscall_err()
  linux-user: fix print_syscall_err() when syscall returned value is
    negative
