[Linux-ia64] minor tidy up of some warnings.

[richard offer <offer@sgi.com>]

Here's a list of some of the issues I found while compiling with the
following warnings enabled

    -Wimplicit-int \
	-Wimplicit-function-declaration \
	-Wimplicit -Wmain -Wreturn-type \
	-Wunused-function -Wunused-label \
	-Wunused-value -Wswitch \
	-Wcomment \
	-Wchar-subscripts -Wparentheses \
	-Werror

Using -Wall -Werror will fail due to a number of unitialized variables
(dummy variables in the _syscall defns in asm/unistd.h)


I always try to build with -Werror set to make the build fail at compile
time rather than execution.

=======

in arch/ia64/kernel/unwind.c:509 is declared inline, in
include/asm-ia64/unwind.h it has no inline modifier.

These are all over the place, basically they are storing something that is
an int into a void * and then getting it back out again (typecasting it as
it comes back out).

Not sure how to handle this. Comments ?
