[PATCH][REDO] arch: x86: trivial changes to make various functions static

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

Functions x86_vector_debug_show, clear_non_loaded_ctxs, uv_handle_nmi
and uv_nmi_setup_common are local to the source and do not need to be
in global scope, so make them static. Fixes up various sparse warnings.

I've combined 3 earlier patches into 1. Apologies for the noise.

v1: sent as separate patches
v2: send as one combined patch as requested by Ingo

x86: Fix Sparse warnings about non-static functions

Functions x86_vector_debug_show(), uv_handle_nmi() and uv_nmi_setup_common()
are local to the source and do not need to be in global scope, so make them
static.

Fixes up various sparse warnings.
