Xen EFI boot how to?
I have a IBM System x3600 series server with UEFI.
I managed to compile the xen EFI (xen-4.2-unstable.efi).
The machine is currently running Ubuntu with grub2.
I can see a grubx64.efi in /boot/efi/EFI/ubuntu/grubx64.efi
Where should I put the xen efi ?
I tried creating a efi/EFI/xen/xen-4.2-unstable.efi and added it as a boot option using efibootmgr.
All I get in that case is a blank screen.

[PATCH] Increasing E820MAX
We found machines with >32 E820 memory map entries, where Xen fails to
boot (but Linux does boot fine). The native Linux (both x86 and x86_86)
already has:
#define E820MAX 128 /* number of entries in E820MAP */

bitopts functions overflowing page boundarys
u.inuse.type_info is at the end of the pfn_info structure, and is
u32 for both x86_32 and x86_64--in this location it can also be the
last 32 bits of a page.
several functions use bitopts.h functions to manipulate this member, and
on x86_64 these functions use u64 instructions, which will overflow the
page boundary, and possibly the end of memory as we see here:
