x86: make x86_32 use tlb_64.c, build fix, clean up X86_L1_CACHE_BYTES
Fix: arch/x86/mm/tlb.c:47: error: ‘CONFIG_X86_INTERNODE_CACHE_BYTES’ undeclared here (not in a function) The CONFIG_X86_INTERNODE_CACHE_BYTES symbol is only defined on 64-bit, because vsmp support is 64-bit only. Define it on 32-bit too - where it will always be equal to X86_L1_CACHE_BYTES. Also move the default of X86_L1_CACHE_BYTES (which is separate from the more commonly used L1_CACHE_SHIFT kconfig symbol) from 128 bytes to 64 bytes. Signed-off-by: Ingo Molnar <mingo@elte.hu>
