[PATCH 0/5] x86/boot/compressed/64: Prepare trampoline memory

[Kirill A. Shutemov]

Here's re-split of the patch that prepares trampoline memory, but doesn't
actually uses it yet. The original patch turned out to be problematic.
Splitting the patch should help to pin down the issue.

The functionality should match the original patch (although I've moved a
bit more into C).

Borislav, could you check which patch breaks boot for you (if any)?
