Hey Jeremy,

Please pull this git:


It has three bootup-fixes that have gatted 2.6.32 tree from booting on some of
my machines:
 - hvc_console would blow up during bootup with the irq handler hitting a
   NULL pointer
 - On Intel i915, if one was to use dom0_mem=1500M the "flush" page would be
   incorrectly allocated in System RAM, and ioremap trying to use the PFN
   instead of the MFN ending disastrously. The fix is to reserve the
   System RAM E820 areas so the reserve API does not use it.
 - On IBM Summit machines (I've a x3850) it would end up using the 
   causing a blowup. Back-ported how we are guard ourselves against this in 

All of these fixes are in 2.6.39-rc0 (or on the way). The machines that boot now
are: IBM x3850, Intel DX58SO,, and G31M-ES2L/G31M-ES2L.

Konrad Rzeszutek Wilk (3):
      xen/hvc: Disable probe_irq_on/off from poking the hvc-console IRQ line.
      xen/e820: Don't mark balloon memory as E820_UNUSABLE when running as 
guest and fix overflow.
      xen/ioapic: Allow set_fixmap to set FIX_APIC_BASE to dummy mapping.

Zhang, Fengzhe (1):
      xen/setup: Inhibit resource API from using System RAM E820 gaps as PCI 
mem gaps.

There is one more fix, which is a back-port of Stefano's patch consulting the 
(or e820_reserve_range) API when clearing the PMDs. That looks to be fixing 
some folks
builds, but I will let Stefano post that one.
