Andrew Turner b7112ead32 Clean up struct syscall_args: 
1. Align to a 64-bit address so 64-bit data will be correctly aligned.
 2. Add a comment explaining why.
 3. Remove an unneeded value from the struct.

This fixes an issue where the struct may not be correctly aligned on the
stack in the syscall function. This may lead to accesing a 64-bit value
at a non 64-bit. This will raise an exception and panic the kernel.

We have been lucky where on arm and armv6 both clang and gcc correctly
align the data, even without us asking to, however, on armeb with clang to
not be the case. This tells the compiler we really do need this to be
aligned.

Reported and tested by:	jmg (on armeb with clang)
MFC after:	1 Week [1, 2]
