[Xen-devel] Re: [PATCH 0/3] x86: remove x86_init.mapping.pagetable_reserve

[Ingo Molnar <mingo@xxxxxxx>]

-tip testing found that these patches cause the following boot crash 
on native:

[    0.000000] Base memory trampoline at [ffff88000009d000] 9d000 size 8192

[    0.000000] Kernel panic - not syncing: alloc_low_page: ran out of memory

Config attached, full bootlog below. I've excluded the commits for 
now.
