* x86: early_idt_handler improvements, 64-bitRoland McGrath2008-01-301-0/+6
| | | | | | | | | | It's not too pretty, but I found this made the "PANIC: early exception" messages become much more reliably useful: 1. print the vector number, 2. print the %cs value, 3. handle error-code-pushing vs non-pushing vectors.

* x86 setup: initialize LDTR and TR to make life easier to Intel VTH. Peter Anvin2008-01-301-0/+3
| | | | | | | | | | | 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.

* x86: <asm/segment.h>: boot GDT entries are 32/64-independentH. Peter Anvin2008-01-301-16/+8
| | | | | | | | | The boot GDT entries are common between 32- and 64-bit mode, so move them to common code instead of having two identical copies. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* x86: remove arch specific segment headersGlauber de Oliveira Costa2008-01-301-2/+175
| | | | | | | | | This file puts the remainder of the arch specificic segment headers in segment.h. Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* x86: unify common parts of segment.hGlauber de Oliveira Costa2008-01-301-0/+16
| | | | | | | | | | Although segment handling in i386 and x86_64 are very different, there's a common part. Put them in segment.h instead of arch specific headers Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* x86: put get_kernel_rpl in a common locationGlauber de Oliveira Costa2008-01-301-0/+9
| | | | | | | | | This macro is useful for both i386 and x86_64, so put it in a common location, where both arches can grab it. Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* i386/x86_64: move headers to include/asm-x86Thomas Gleixner2007-10-111-0/+5
Move the headers to include/asm-x86 and fixup the header install make rules Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
