The issue w/ efi_reserve_boot_services exists across several
versions and distros of linux. So, I'd like to find a fix that
works across several kernel versions and distros.
the kernel and required utility code to allocate high isn't available
on distros based on pre 3.9 kernels.
While the alloc high code is a step in the right direction, it is
still green. We are having much more problems getting crash dump
to work w/ top of tree kernels/utilities than we are having w/
distros running legacy bits.
Back porting this much larger change to multiple versions and
multiple distros isn't my first choice as its is much more work, much
more likely to destabilize distros w/ legacy kernels.
We will be passing along fixes for these other top of tree dump
issues as we find them, but our first priority is enabling
our distro partners that happen to be using pre 3.9 based kernels.
