[PATCH 0/6] Remove some usage of shadow variable

[Julien Grall <julien.grall@citrix.com>]

Hi all,

I wrote this patch series after noticing that one of my series [1] was
shadowing a variable and GCC didn't warn it.

So I've turned on -Wshadow and look at if there is other places abusing
of shadow variable in Xen.

This series is not complete and only contain the more simple changes.

I'd like to have some input to know whether turning on -Wshadow would be
sensible in the future.

Regards,
