Subject: [PATCH 35/58] x86: arch/x86/kernel/asm-offsets.c: Add prototype for dummy function common

arch/x86/kernel/asm-offsets.c defines an intentionally unused function
common, just to slurp out the generated assembly and obtain the values
for some constants.  Add a prototype of this function, to satisfy GCC
(-Wmissing-prototypes) and Sparse (-Wdecl).

arch/x86/kernel/asm-offsets.c:30:6: warning: no previous prototype for ‘common’ [-Wmissing-prototypes]
