What's left in processor_32.h and processor_64.h cannot be cleanly
integrated. However, it's just a couple of definitions. They are moved
to processor.h around ifdefs, and the original files are deleted. Note that
there's much less headers included in the final version.

This patch moves the TASK_ALIGN constraints to common header.
The base of it is the same for x86_64 and i386. The only difference

safely use the same code for both.

Although slighly different, the tss_struct is very similar in x86_64 and

now called x86_hw_tss, and each of the architectures provides yours.

this patch changes write_idt_entry signature. It now takes a gate_desc
instead of the a and b parameters. It will allow it to be later unified
between i386 and x86_64.

To account for the differences in gate descriptor in i386 and x86_64
a gate_desc type is introduced.

This patch changes the name of x86_64 macro used to access the per-cpu
gdt. It is now equal to the i386 version, which will allow code to be shared.

Since the last version of it received no comments on the interfaces, here
it goes a version, that I feel ready for inclusion.
The comments regarding style, specially the elimination of the #defines in
the desc_struct definition were merged. I also implemented the vmi
functions,
missing last time.
This file puts the remainder of the arch specificic segment
headers in segment.h.

Hi,
In this patch, I unify segment_32.h and segment_64.h into segment.h
They have some common parts, but a considerable ammount of code still has
to be around ifdefs.
The only patch that is really important to paravirt is the first one, that
moves a paravirt definition into the common header. Th
This macro is useful for both i386 and x86_64, so put it in a common
location, where both arches can grab it.

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

Which is fine, it's all the same in the end. Just with more shift
rights, and more visual pollution.
