Subject: [PATCH 14/16] arch: x86: xen: Mark internal function xen_flush_tlb_all static.

xen_flush_tlb_all is defined only in mmu.c, so mark it static.

This eliminates the following gcc warning:

arch/x86/xen/mmu.c:1211:6: warning: no previous prototype for ‘xen_flush_tlb_all’ [-Wmissing-prototypes]
