2008-07-17x86: unify and correct the GDT_ENTRY() macroH. Peter Anvin
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.

2008-01-30x86 setup: correct the base in the GDT_ENTRY() macroH. Peter Anvin
The GDT_ENTRY() macro in pm.c would incorrectly cut the bottom 8 bits off the base. We didn't define any bases with the bottom 8 bits nonzero, so it is a non-manifest bug, but it's still a bug.

2008-01-30x86 setup: initialize LDTR and TR to make life easier to Intel VTH. Peter Anvin
Intel VT doesn't like to engage when the protected-mode state isn't fully initialized. Make life easier for it by initializing LDTR (to null) and TR (to a dummy hunk of low memory which will never actually be touched.) Signed-off-by: H.
