[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 */

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.

Bug: Limitation of <=2GB RAM in domU persists with 4.3.0
I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU
passthrough without crashes. Unfortunately, the same crashes still
happen. Massive frame buffer corruption on domU before it locks up
solid. It seems the PCI memory stomp is still happening.
I am using qemu-dm, as I did on Xen 4.2.x.
So whatever fix for this went into 4.3.0 didn''t fix it for me.

[RFC PATCH 0/2] GLOBAL() macro for asm code.
Hello,
This series has been split into two patches, one for arm and one for x86. I
figured that this was easier than doing it as a single combined patch,
especially as the changes are functionally independent.
x86 has been boot tested, but arm has not even been compile tested as I lack a
suitable cross compiler. However, the changes are just text replacement, so I
dont expect any issues.
The
