x86: unify and correct the GDT_ENTRY() macro

2008-07-17T18:29:24+00:00

Merge the GDT_ENTRY() macro between arch/x86/boot/pm.c and
arch/x86/kernel/acpi/sleep.c and put the new one in
.

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
 in .

x86: move x86_64 gdt closer to i386

2008-07-08T10:48:16+00:00

i386 and x86_64 used two different schemes for maintaining the gdt.
With this patch, x86_64 initial gdt table is defined in a .c file,
same way as i386 is now. Also, we call it "gdt_page", and the descriptor,
"early_gdt_descr". This way we achieve common naming, which can allow for
more code integration.

x86: don't set up early exception handlers for external interrupts

2008-04-17T15:41:29+00:00

All of early setup runs with interrupts disabled, so there is no
need to set up early exception handlers for vectors >= 32

This saves some minor text size.

x86: early_idt_handler improvements, 64-bit

2008-01-30T12:33:06+00:00

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 VT

2008-01-30T12:33:02+00:00

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.)

x86: : boot GDT entries are 32/64-independent

2008-01-30T12:33:01+00:00

The boot GDT entries are common between 32- and 64-bit mode, so move
them to common code instead of having two identical copies.

x86: unify common parts of segment.h

2008-01-30T12:31:09+00:00

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

x86: put get_kernel_rpl in a common location

2008-01-30T12:31:09+00:00

This macro is useful for both i386 and x86_64, so put it in a common
location, where both arches can grab it.
