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 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 Markus Armbruster (8): exec: Fix Xen RAM allocation with unusual options exec: Clean up fall back when -mem-path allocation fails exec: Reduce ifdeffery around -mem-path exec: Simplify the guest physical memory allocation hook exec: Drop incorrect & dead S390 code in qemu_ram_remap() exec: Clean up unnecessary S390 ifdeffery exec: Don't abort when we can't allocate guest memory pc_sysfw: Fix ISA BIOS init for ridiculously big flash exec.c | 121 ++++++++++++++++++++++++++---------------------- hw/block/pc_sysfw.c | 5 +- include/exec/cpu-all.h | 2 - include/exec/exec-all.h | 2 + include/sysemu/kvm.h | 5 -- kvm-all.c | 13 ------ target-s390x/kvm.c | 23 +++------ util/oslib-posix.c | 4 +- util/oslib-win32.c | 5 +- 9 files changed, 78 insertions(+), 102 deletions(-) -- 1.7.11.7
