x86: unify and correct the GDT_ENTRY() macro
Merge the GDT_ENTRY() macro between arch/x86/boot/pm.c and arch/x86/kernel/acpi/sleep.c and put the new one in <asm-x86/segment.h>. While we're at it, correct the bitmasks for the limit and flags. The new version relies on using ULL constants in order to cause type promotion rather than explicit casts; this avoids having to include <linux/types.h> in <asm-x86/segments.h>. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
