[Qemu-devel] [PATCH 1/2] s390: Fix ram_size updating in machine init

[Alexander Graf <agraf@suse.de>]

From: Heinz Graalfs <graalfs@linux.vnet.ibm.com>

The global variable 'ram_size' is hidden by the local variable
declaration in s390_init(). Since we want to update the global
ram size in certain cases we must not use a local ram_size
variable.
- This fixes booting with unusual ram sizes like -m 67001
- This changes behaviour back to the situation before commit

  (create struct for machine initialization arguments)
