Fix head_32.S gcc bignum warnings when CONFIG_PAE=y. arch/x86/kernel/head_32.S: Assembler messages: arch/x86/kernel/head_32.S:225: Warning: left operand is a bignum; integer 0 assumed arch/x86/kernel/head_32.S:609: Warning: left operand is a bignum; integer 0 assumed The assembler was stumbling over the 64-bit constant 0x100000000 in the KPMDS #define. Testing: a cmp(1) on head_32.o before and after shows the binary is unchanged.
