Subtracting before cast produce same result but remove following warnings from sparse: arch/x86/include/asm/pgtable_types.h:255:38: warning: cast truncates bits from constant value (100000000 becomes 0) arch/x86/include/asm/pgtable_types.h:270:38: warning: cast truncates bits from constant value (100000000 becomes 0) arch/x86/include/asm/pgtable.h:127:32: warning: cast truncates bits from constant value (100000000 becomes 0) arch/x86/include/asm/pgtable.h:132:32: warning: cast truncates bits from constant value (100000000 becomes 0) arch/x86/include/asm/pgtable.h:344:31: warning: cast truncates bits from constant value (100000000 becomes 0) 64-bit or PAE machines will not be affected by this change.
