Cover letter [PATCH 00/12] x86: Cleanup idt, gdt/ldt/tss structs

Hi -

This is my first submission to the kernel, so (beware!) please let me know if I can make any improvements on these patches.

I attempted to clean up the x86 structs for 32bit cpus that store IDT/LDT/GDT data by removing the fields labeled "a" and "b" in favor of more descriptive field names. I added some macros and went through the kernel cleaning up the various places where "a" and "b" were used.

I tried building my kernel with my .config and then also did a make allyesconfig build to help ensure I found everything that was using the old structure names. I also tried a few grep patterns. Hopefully I got everyone out.

Thanks,
Joe Damato
