Subject: [patch] espfix code cleanup

Hi.

The current espfix code used to make problem for some
people by its uglyness and the stack switching.
The attached patch removes about 2/3 of the mess by
utilizing the 32bit stack instead of the 16bit one.
I simply patch the base address at gdt so that the
kernel esp have the same high word as the user esp.

In case there are no objections - Andrew, could you please apply?

Clean up the espfix code by utilizing the 32bit stack
instead of the 16bit one.
