[PATCH 0/4] efi: PE header generation fix
The PE headers of the generated efi file were quite buggy. And since OVMF
perform a few consistency checks, syslinux was unable to run on it. I don't
pretend to have a thorough understanding of the PE+ headers, some bugs may
remain. :)

another RFC patch: bzImage with ELF payload
...One thing that fell out of this is that code32_start end up being a
pointer to the ELF header rather than an entrypoint. Rather than
reproducing Vivek's (?) hack of making the ELF header itself executable,
I changed the 16-bit code to check for an ELF magic number at
code32_start and use the e_entry to get the actual entrypoint. This
seems like approximately the right way of doing this, but I'm not sure
how we want to formalize it. It's certainly easier than trying to
extract the payload's entry address and copying it to code32_start in
the boot_params block, and we need a pointe...

[PATCH] Support cross-bitness guest when core-dumping
This patch allows core-dumping to work on a cross-bit host/guest configuration, whereas previously that was not supported. It supports both PV and FV guests. The core file format generated by the host, needs to match that of the guest, so an alignment issue is addressed, along with the p2m frame list handling being done according to the guest size.
