* x86: remove zImage supportH. Peter Anvin2009-03-111-44/+0
| | | | | | | | | | | | | | | | | | Impact: obsolete feature removal The zImage kernel format has been functionally unused for a very long time. It is just barely possible to build a modern kernel that still fits within the zImage size limit, but it is highly unlikely that anyone ever uses it. Furthermore, although it is still supported by most bootloaders, it has been at best poorly tested (or not tested at all); some bootloaders are even known to not support zImage at all and not having even noticed. Also remove some really obsolete constants that no longer have any meaning. LKML-Reference: <49B703D4.1000008@zytor.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* x86: unify and correct the GDT_ENTRY() macroH. Peter Anvin2008-07-171-6/+0
| | | | | | | | | | | | | 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.

* x86 setup: correct the base in the GDT_ENTRY() macroH. Peter Anvin2008-01-301-1/+1
| | | | | | | | | | | | 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. Pointed out by John Smith <johnsmith9344@gmail.com>.

* x86 setup: initialize LDTR and TR to make life easier to Intel VTH. Peter Anvin2008-01-301-0/+4
| | | | | | | | | | | 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.
