[Xen-devel] [PATCH v3 0/3] xen: support of large memory maps

[Juergen Gross <jgross@xxxxxxxx>]

This patch series is the first part for adding support of large EFI
memory maps (> the current limit of 128 entries) while reducing
trampoline size.

I'm not posting the final patch for making the trampoline size
reduction effective in order not to add major rebase work to Daniel's
multiboot2 series.

Tested and verified the Xen-e820 has been used in the test. Suspend and
resume have been verified to work, too.

Juergen Gross (3):
  xen/x86: split boot trampoline into permanent and temporary part
  xen/x86: use trampoline e820 buffer for BIOS interface only
  xen/x86: support larger memory map from EFI
