[Qemu-devel] [PATCH v3 for 1.6 0/8] Guest memory allocation fixes & cleanup

[Markus Armbruster <armbru@redhat.com>]

All I wanted to do is exit(1) instead of abort() on guest memory
allocation failure [07/08].  But that lead me into a minor #ifdef bog,
and here's what I brought back.  Enjoy!

Testing:
* Christian Borntraeger reports v1 works fine under LPAR (new S390
  KVM, i.e. generic allocation) and as second guest under z/VM (old
  S390 KVM, i.e. legacy S390 allocation).  Thanks for testing, and for
  catching a stupid mistake.  v2 differs from v1 only in code that
  isn't reachable on S390.

Changes since v2:
* Straightforward rebase, only 4/8 conflicted
Changes since v1:
* 5/8: Fix assertion in qemu_ram_remap() (Paolo)
* All other patches unchanged except for Acked-by in commit messages
Changes since RFC:
* 1-3+8/8 unchanged except for commit message tweaks
* 4+6/8 rewritten to address Paolo's review
* 5/8 rewritten: don't fix dead code, just assert it's dead
* 7/8 fix mistakes caught by Richard Henderson and Peter Maydell
