this series resolves an issue for hvc back-ends that transfer

Hello, i'm developing an embedded linux system on a custom mpc5200b board, at
University.
We have a problem with a custom version of kernel: 2.6.23 and 2.6.33. We can't
use newer version at the moment.
We are able to compile and load the kernel on Freescale Lite5200b and on Custom
Board.
Macro get_unused_fd() is used to allocate a file descriptor with
default flags. Those default flags (0) can be unsafe:
O_CLOEXEC must be used by default to not leak file descriptor
across exec().
Instead of macro get_unused_fd(), functions anon_inode_getfd()
or get_unused_fd_flags() should be
the macro is not going to break modules ABI.
In linux-next tag 20130702, they're currently:
- 15 calls to get_unused_fd_flags()
not counting get_unused_fd() and anon_inode_getfd()
- 14 calls to get_unused_fd()
- 11 calls to anon_inode_getfd()
The following patchset try to convert all calls
