[Qemu-devel] [PATCH 0/4] Don't abort when we can't allocate guest memory (again)

[Markus Armbruster <armbru@redhat.com>]

Not nice:

    $ qemu-system-x86_64 -m 10000000
    Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456:
    upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory
    Aborted (core dumped)

I fixed this in commit 3922825 for v1.7, but commit ef701d7 regressed
it for v2.2, and now I'm fixing it again, only this time the fix is
fifteen times bigger.

Folks involved in the flawed commit cc'ed, so they can do penance by
reviewing my fix ;-P

PATCH 1/4's error_fatal obviously enables further simplifications.  I
got some in my local tree, but they're not ready, yet.

Markus Armbruster (4):
  error: New error_fatal
  Fix bad error handling after memory_region_init_ram()
  loader: Fix memory_region_init_resizeable_ram() error handling
  memory: Fix bad error handling in memory_region_init_ram_ptr()
