Here's the second round of my patches to fix up the problems that we're seeing with the XENMEM_machine_memory_map hypercall. These few simple changes, to give xen_e820_map some extra space, get things working fine on our large machine. This version of the patchset adds a patch to remove the #ifdef CONFIG_EFI conditional around the definition of E820_X_MAX, so that it's always slightly larger than E820MAX. I've also tweaked the code that works on xen_e820_map to use ARRAY_SIZE(xen_e820_map) instead of using E820_X_MAX directly, as suggested by Boris. As always, I appreciate any input that others can give! - Alex Alex Thorlton (2): x86: Make E820_X_MAX unconditionally larger than E820MAX xen/x86: Increase xen_e820_map to E820_X_MAX possible entries arch/x86/include/asm/e820.h | 8 +++----- arch/x86/xen/setup.c | 6 +++--- 2 files changed, 6 insertions(+), 8 deletions(-) -- 1.8.5.6
