Note to maintainers: the patch 02 implements a test case for 
https://www.mail-archive.com/qemu-devel@nongnu.org/msg588166.html which 
is in Paolo's queue already.

[Qemu-devel] [PATCH v2 1/2] Acceptance tests: use linux-3.6 and set vm memory to 4GiB

2019-01-27 Thread Li Zhijian
QEMU have already supported to load up to 4G initrd if the sepcified memory is
enough and XLF_CAN_BE_LOADED_ABOVE_4G is set by guest kernel

linux-3.6 kernel shipped by Fedora-18 cannot support xldflags so that it
cannot support loading more than 2GiB initrd
