[PATCH 1/11] - UML 64-bit cleanups in the system calls

[PATCH 1/11] - UML 64-bit cleanups in the system calls

[Jeff Dike]

[ The beginning of a series of 11 patches, the signal ones bang heavily on
the same code, so merging will be much more pleasant if they are applied in
order ]

64-bit cleanup - this fixes the return values of the system calls to
be longs.
