6d6ef97dba Bring over the code from sys/i386/i386/mp_machdep.c, r187880

9198d09682 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

99642cdfcb - 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

a1ec700ce8 Remove ipi_all() and ipi_self() as the former hasn't been used at 
all to date and the latter also is only used in ia64 and powerpc
code which no longer serves a real purpose after bring-up and just
can be removed as well. Note that architectures like sun4u also
provide no means of implementing IPI'ing a CPU itself natively
in the first place.

d1fd89a35e 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.

ad33f05a7c enable the xen_guest string so that the freebsd xen kernel will 
at least pass muster with the loader on 3.0.3

Note that this doesn't actually make it work as Xen 3.0.3
appears to disallow recursive mappings on the page directory
