SubjectRe: [PATCH v2 0/5] Allow the trampoline to use EFI boot services RAM

Ok, so I like this series - if Matt acks it I can apply it.

How urgent is it? The 'laptop does not boot' aspect worries me - how frequently
are systems hit by this?

The approach you chose looks sufficiently robust and straightforward to me, so it
ought to work fine even for x86/urgent - but we can phase it into efi/core as well
if Matt prefers that.

Thanks,

Ingo
