[PATCH 0/2] linux-user: Small fix for copy_file_range

From: Giuseppe Musacchio <thatlemon@gmail.com>

An unwanted sign-extension is currently making the host kernel return EOVERFLOW
when calling copy_file_range with a count of 0xffffffff, despite the host being
a 64bit platform.

The fix is only affecting 32bit targets on 64bit hosts, it's a no-op when the
target bitness matches the host one.

As a bonus add a pretty-printer for copy_file_range syscall.

Giuseppe Musacchio (2):
  linux-user: Add copy_file_range to strace.list
  linux-user: Fix erroneous conversion in copy_file_range
