[PATCH 0/5] [GSoC - x86_64] Add interrupts and clock driver

[Amaan Cheval]

This patch series includes all of my remaining work so far on the x86_64 BSP. It
supports:

* Static paging support using 1GiB superpages
* RTEMS interrupts
* A fairly accurate clock driver based on the APIC timer calibrated by the PIT

ticker.exe passes reliably on -O0 optimization level, and it seems like it
_should_ on -O2 as well, except for the issue I've been describing on this
thread:
