Subject[PATCH 3/5] ia64: Replaced the system call table entry from entry.S
Date
In IA64, system call table entries are the part of entry.S file. We
need to keep it in a seperate file so that one of the patch in this
patch seriers does have a system call table generation script which
can seperatly handle system call table entries.

Replaced the system call table from entry.S to new file - syscall.S,
and this change will unify the implementation across all the
architecture and to simplify the implementation for system call
table generation using the script.
