3a6d1fcf9c merge 186535, 186537, and 186538 from releng_7_xen 
Log:
 - merge in latest xenbus from dfr's xenhvm
 - fix race condition in xs_read_reply by converting tsleep to mtx_sleep

Log:
 unmask evtchn in bind_{virq, ipi}_to_irq

Log:
 - remove code for handling case of not being able to sleep
 - eliminate tsleep - make sleeps atomic

9bf38e47a3 - move gdt, ldt allocation to before KPT allocation 
- fix bugs where we would:
    - try to map the hypervisors address space
    - accidentally kick out an existing kernel mapping for some domain creation memory allocation sizes
    - accidentally skip a 2MB kernel mapping for some domain creation memory allocation sizes
- don't rely on trapping in to xen to read rcr2, reference through vcpu
- whitespace cleanups

57bd99b3c5 Some people have very strange notions of how large KVA_PAGES should be. The 
core of this change generalizes the initial page directory setup so that
the kernel can be given arbitrarily large or small.

- small formatting fixes
- update copyright

allocated memory - this lets us boot with 3GB
