[PATCH] x86_64 machine_kexec: Cleanup inline assembly.

Browse source

In an uncensored copy of code from i386 to x86_64 I wound up
with inline assembly with the wrong constraints.  Use input
constraints instead of output constraints.

So I know the assembler will do the right thing specify the size
of the operand lidtq and lgdtq instead of just lidt and lgdt.

Make load_segments use an input constraint, and delete the macro fun.
Without having to reload %cs like I do on i386 this code is noticeably
simpler.
