Subject: [PATCH] x86/unwind/orc: make some symbols static

Fix the following sparse warning:

arch/x86/kernel/unwind_orc.c:19:5: warning: symbol 'cur_orc_ip_table'
was not declared. Should it be static?
arch/x86/kernel/unwind_orc.c:20:18: warning: symbol 'cur_orc_table' was
not declared. Should it be static?
arch/x86/kernel/unwind_orc.c:22:14: warning: symbol 'lookup_num_blocks'
was not declared. Should it be static?
arch/x86/kernel/unwind_orc.c:23:6: warning: symbol 'orc_init' was not
declared. Should it be static?
